Inc. will provide RAIDWatch and controller firmware updates periodically via our distributors and sales offices. 1.7 Installation Overview This manual can be used to install any of the following ER2510FS RAID Controller Head models: • ER2510FS-4S • ER2510FS-6S • ER2510FS-4RH • ER2510FS-6RH The variations between these models are described below. 1.8 Model Variations The ER2510FS RAID Controller Head, described in this manual comes in four different models (see above). Variations between these models give users extreme configuration flexibility and enable them to configure storage management subsystems that are uniquely suited to their needs. The differences between the four models are described below. 1.8.1 Four Models The four models can be separated into two controller categories, single-controller models and dual redundant controller models. Introduction 1-5 Model Controller/s Controller Mode ER2510FS-4S 1 x IFT5251F-4 Single ER2510FS-6S 1 x IFT5251F-6 Single ER2510FS-4RH 2 x IFT5251F-4 Dual-Redundant ER2510FS-6RH 2 x IFT5251F-6 Dual-Redundant Table1-1: - ER2510FS Models Single Controller Models: - These models should be used when there is a low demand on data availability and a fully redundant system is not a critical requirement for the system. Dual Redundant Models: - Dual-active configurations may require dual loops to create full path redundancy. There are no single points of failure in a dual-active configuration and they should therefore be used when data accessibility is a critical requirement of the storage network that is being implemented. 1.8.2 Fibre Channels Different models come with varying number of fibre channels and single IO module type. These IO modules are referred to as Type-1 IO Modules and they are fully described in Chapter 2. The ER2510FS-4S, and ER2510FS-4RH only come with four available fibre channels. The system is designed to accommodate 6 IO Channel Modules (see Chapter 2). Dummy canisters are provided in the place of the additional IO modules. WARNING The dummy canisters that come with the four channel controller models must be installed into the system. They are provided so that the airflow from the fans can be normalized. If the airflow is 1-6 Introduction not normalized the system will overheat, be permanently damaged and void our warranty. Single Controller Models Model Fibre Channels ER2510FS-4S 4 ER2510FS-6S 6 Table1-2: - IO Module Types for Single-Controller Models Dual-Redundant Controller Models Model Fibre Channels ER2510FS-4RH 4 ER2510FS-6RH 6 Table1-2: - IO Module Types for Dual-Redundant Controller Models RCC Channels: - Both the redundant Controller Models come with preset channels for Redundant Controller Communication (RCC) connection. In the ER2510FS-6RH if CH4 or CH5 have no external FC cables connected to them, they can be used as dedicated RCC Channels. If cables are connected to these channels then they can be used as drive + RCC channels. CH2 and CH3 on the ER2510FS-4RH are both drive + RCC channels. 1.8.3 Active Component Variations The single controller models, the ER2510FS-4S and ER2510FS-6S, only come with: Introduction 1-7 • A single maintenance module • A single battery backup unit (BBU) The redundant models have two each of the above components. Instead of receiving these active components, users will receive dummy canisters in their place. It is imperative that these canisters be installed. They regulate the airflow within the enclosure. WARNING The dummy canisters that come with the single controller models must all be installed into the system. They are provided so that the airflow from the fans can be normalized. If the airflow is not normalized the system will overheat and be permanently damaged. 1-8 Introduction CHAPTER 1: INTRODUCTION ..........................................................1-1 1.1 ABOUT THIS MANUAL .....................................................................1-1 1.2 WHO SHOULD READ THIS MANUAL .................................................1-1 1.3 HOW TO READ THIS MANUAL ..........................................................1-2 1.3.1 Unpacking................................................................................1-2 1.3.2 Identifying Components............................................................1-2 1.3.3 Installation...............................................................................1-2 1.4 CONVENTIONS .................................................................................1-3 1.4.1 Naming ....................................................................................1-3 1.4.2 Warnings .................................................................................1-3 1.4.3 Cautions...................................................................................1-3 1.4.4 Notes........................................................................................1-4 1.4.5 Lists .........................................................................................1-4 1.5 RELATED DOCUMENTS ....................................................................1-4 1.6 SOFTWARE AND FIRMWARE UPDATES ..............................................1-5 1.7 INSTALLATION OVERVIEW ...............................................................1-5 1.8 MODEL VARIATIONS ........................................................................1-5 1.8.1 Four Models.............................................................................1-5 1.8.2 Fibre Channels.........................................................................1-6 1.8.3 Active Component Variations ...................................................1-7 controller head, 1-1 Generic Operation Manual, 1-4 dual redundant, 1-6 dummy canister, 1-8 RAIDWatch, 1-5 RCC Channel, 1-7 firmware, 1-5 single-controller, 1-6 Introduction 1-9 Chapter 2: Hardware Overview 2.1 The ER2510FS RAID Controller Head The ER2510FS RAID Controller Head is a rectangular enclosure divided into a front and rear section.

When a user powers up the system the model name will appear on the screen. Hardware Overview 2-7 NOTE When a user powers up the system they must check the LCD panel and check the model name. If the model name that appears on the screen is not the same as the model the user ordered they should notify their distributor immediately. The LCD Module Display also shows relevant and important system information and can be used to both configure and monitor the system. Some models have a single controller and other models have dual-single or dual redundant controllers. The following specifies the information that is shown on the screen for each configuration type. Figure 2-8: - Front Panel LCD Module Single Controller: The LCD module shows Controller A status. The controller MUST be inserted into the slot reserved for controller A (see figure 2-1). Redundant Controllers During the boot-up process the status of Controller A will be shown. It will then swap to show the Primary controller status. The primary controller is determined automatically. 2-8 Hardware Overview 2.4.2 IO Modules Part Number: IFT-9560-IO1 The first six slots (slot 0 - slot 5) on the Front Panel of the ER2510FS RAID Controller Head are reserved for IO Modules. Each model comes with either four or six IO Modules. If you have purchased a four-channel model (ER2510FS-4S or ER2510FS4RH), you will receive two dummy IO canisters that must be installed. The ER2510FS RAID Controller Head supports a single IO Module variant, which is referred to as the Type-1 IO Module. Type-1 IO Modules come with two SFP sockets and a single speed selection jumper that enables the user to select the speed of the fibre link. The SFP sockets enable users to connect external fibre channel devices to the controllers. (Please refer to Section 3.10 for the jumper settings and to Section 4.4.1 for the LED definitions.) Type-1 IO Modules also come with an onboard bypass circuit. To Controller A SFP by-pass circuit Hot Swappable Connector SFP To Controller B Figure 2-9: - Type-1 IO Module Bypass circuit Hardware Overview 2-9 The bypass circuit connects the fibre channels of both controllers together and negates the need for the provision of an external bypass function. The bypass circuits on the Type-1 IO modules enable the users to easily configure fully redundant data paths to both the Host and the storage enclosure.

The controller module contains the RAID controller that facilitates the transfer of data between the host and the drive enclosure WARNING Although the RAID Controller can be removed, the only time a user should touch the controller itself is to install the memory modules (see Chapter 3). Unnecessary tampering with the RAID controlle can damage the controller the system unusable. Hardware Overview 2-15 RAID Controller Board Rear Flap Cooling FAN Module Figure 2-15: RAID Control Module with cooling FAN Module Two RAID Controller Module variations can be used in the ER2510FS RAID Controller Head. The IFT-9560-CTMod-4 has a pre-installed IFT5251F-4 controller, and the IFT-9560-CTMod-6 has a pre-installed IFT5251F-6 controller. Flaps at the back of the controller module are used to secure/remove the controller module in/from the chassis. If the controllers are installed in redundant configuration they can be hot-swapped. The RAID Controllers used in these modules are fibre-to-fibre 2GHz. They come with point-to-point and fully featured FC-AL support on the drive side. The host side supports point-to-point, fully featured FC-AL and Fibre Switch connectivity. 2.5.2 Cooling FAN Module Part Number: IFT-9560-FanMod (cooling FAN module) IFT-9560-Fan (individual FAN unit) A single cooling FAN module and a dummy module accompany the single controller modules. The redundant models come with two cooling FAN modules. These cooling FAN modules must be 2-16 Hardware Overview installed. Each cooling FAN module is assigned to cool a single controller module. The cooling FAN module consists of two individual FANs, if one of these fans should fail the second individual fan can keep the controller module sufficiently cooled. Both cooling FAN modules have simple hot-swappable mechanisms, which are independent of each other and the controller modules and makes changing FAN modules fast and easy. CAUTION Although an individual FAN in the cooling FAN module can sufficiently cool a controller module it is not recommended. If you are using a single FAN and it should fail then the system can overheat. Failed FANs should be replaced as soon as possible. Delays in FAN replacements can lead to irreparable system damage. Hardware Overview 2-17 Independent Fan Silver spring screw Individual fan Figure 2-16: - Cooling FAN Module NOTE A complete list of specifications for the individual fans contained in the cooling FAN module can be found in Apppendix B. 2.5.3 Power Supply Units Part Number: IFT-9560-PSU All the models in the ER2510FS series come with two PSUs. These PSUs are fully redundant. If one PSU fails the other PSU can supply a sufficient amount of power for the system to continue running. CAUTION Although it is possible to run the storage system with a single PSU, it is not recommended. If your system only has a single PSU and this unit fails then the data storage arrays and the storage network managed by the controller head will become inaccessible. 2-18 Hardware Overview NOTE A complete list of specifications for the PSUs can be found in Apppendix B. The PSUs are contained in a single internal rack that is pre-mounted in the controller head. The PSUs are secured within this premounted rack by an external crossbar that is passed through the rear handles of the PSUs and attached to either side of the internally installed rack.

The controller slots are found at the rear of the controller head. The location of controller A and controller B are specified by two labels, which are placed on the top surface of the controller head. Controller A’s slot is indicated by a “Controller A” label and the controller B’s slot is indicated by a “Controller B” label. 3-6 Hardware Installation 3.7 Memory Installation NOTE: The controllers that are installed in the controller module are able to support a cache size between 64MB and 1GB on one SDRAM DIMM with or without ECC support. The controllers ONLY support 133MHz SDRAM. The ER2510FS RAID Controller head comes with one or two RAID Controller Modules (depending on the model). Each controller module contains a RAID Controller Board. The SDRAM DIMMs are not installed on the controllers. The SDRAM modules must be purchased and installed separately. For a dual redundant controller configuration the modules should be equal in size and performance. Install these chips with care. WARNING 1. When you install the cache memory chips it is necessary to remove the controller board from the controller module. Do this with care and consideration in order not to cause permanent damage to the board. This is the only time the controller board should be touched by the user. 2. Please purchase the correct memory modules from your ER2510FS Controller Head vendor/distributor. Steps 1. DIMMs must be installed before the RAID Controller Module is installed. Note, if you are installing controllers in a redundant configuration the DIMMs must BE THE SAME SIZE. CAUTION If you are installing the RAID Controllers in a Dual Redundant configuration, the memory capacity of the DIMMs should be identical Hardware Installation 3-7 2. Remove the Controller Board. The controller board is attached to the base adapter board with five screws. These screws must be removed (refer to figure 3-2). Controller Board Controller Module Canister Figure 3-2: - Remove the controller board from the controller module CAUTION When you remove the controllers from the controller modules to insert the DIMM slots, please place the controllers on an antistatic pad.

LEDs, Audible Alarms, Firmware and Software can all be used to monitor the status of the ER2510FS Controller Head. The ER2510FS also supports SCSI Enclosure Services (SES) monitoring or the drive enclosure. 4.2 System Monitoring The system can be monitored in five different ways:• Firmware: - using the front panel LCD screen or the PC HyperTerminal program. • LEDs: - the front panel modules all have LEDs on the front. These LEDs are used to inform the end user about different system information. • Software:- using a GUI called RAIDWatch. • Audible Alarm: - an audible alarm will be triggered when certain system thresholds are violated. The alarm is used to notify, alert or warn a user about different events. Examples of Monitoring The System 4-1 these events are temperature and voltage. For more details refer to section 4.6. • SES Monitoring: - the RAID Controller Head supports SES monitoring of the drive enclosure. For more details refer to section 4.7. NOTE: The controller head devices are not monitored via SES. Only the drive enclosures are monitored with SES. 4.3 Firmware The firmware is pre-installed on the controller boards. It is used to configure and access system information. Both the front panel LCD screen and a PC terminal can access it. Using the Firmware to configure and monitor the system has been fully described in the “Generic Operation Manual” that came with your system. Please refer to this manual for further information. 4.4 Front Panel LEDs 4.4.1 IO Modules Type-1 IO modules have two green LEDs on the front side of the board. The upper LED belongs to controller A and the lower one to controller B. This LED informs the end user of the channel’s current speed and status. 4-2 Monitoring The System Controller A LED Type 1 IO Module Controller B LED Figure 4-1:- IO Module LEDs • GREEN LED – Channel Speed and Status ON FC at 2GHz OFF FC at 1GHz If a controller is removed from the controller bay and replaced with a blank controller module, the corresponding LED will not have any function. 4.4.2 LED Board The LED Board comes with two vertical LED arrays. Each array contains six LEDs . These LEDs inform the user of the status of both controllers. The column on he left informs the user of the status of controller A and the column on the right informs the user on the status of controller B. The following diagram shows the LED panel with all the LEDs labeled.

The following briefly describes the installation steps for the RAIDWatch Manager. More detailed information on the installation process and how to use the RAIDWatch manager can be found in the Generic Operation Monitoring The System 4-7 Manual, that came with the system, and in the RAIDWatch User’s Manual. NOTE: The RAIDWatch User Manual can be found on the CD that came with the system. To access the RAIDWatch User’s Manual please refer to this file. 4.5.1 Notification Processing Center (NPC) The NPC is a powerful module that runs as a background Disk and Executive Monitor (DAEMON) independent from RAIDWatch that can, itself, be installed redundantly on different hosts. It is used for event notification over Email, fax, LAN broadcast, SNMP traps, etc. It helps to prevent blind time and keeps a user constantly informed as to the status of the storage management subsystem. 4.5.2 Requirements The requirements for a computer running web-based RAIDWatch are the same as those for the clients described in the RAIDWatch User Manual. Java plug-in us also necessary for a management station. 4.5.3 Ethernet Ports The ER2510FS RAID Controller Heads all come with an ethernet LAN port for each controller. These LAN ports can be found on the maintenance modules on the front panel (slot 7 and slot 8). 4.5.4 Installation Steps 1. 4-8 Install the RAIDWatch onto the host computer. Follow the installation instructions that are given in the RAIDWatch User Manual. Monitoring The System 2. Use the Firmware to create a logical array (see the Generic Operation Manual). Make sure that you reserve a space of at least 256MB. This reserved space is required for the RAIDWatch Files that will be transferred to the RAID Controller. CAUTION: If you do not reserve a space of at least 256MB, you will not be able to transfer the necessary RAIDWatch files to the controller and will therefore be unable to use the RAIDWatch Program. 3. Use the firmware to assign an IP address to the controller and specify the NetMask and gateway values. To do this please refer to the Generic Operation Manual. 4. FTP the following RAIDWatch Programs to the designated controller address. • • • • Grm.htm Grm.jar Grem.htm Grem.jar The “grm” files are the RAIDWatch Management Files. The “grem” files are the RAIDWatch event log files. 5. To access the RAIDWatch program, open your web borwser and type in http://aa.bb.cc.dd/grm.htm (where aa.bb.cc.dd s the controller IP address). To view the event log type in http://aa.bb.cc.dd/grem.htm. NOTE: The controller IP address must be requested from the local LAN Manager. 6. For futher instructions on how to use the RAIDWatch program to manage and maintain your system please refer to the RAIDWatch User Manual. Monitoring The System 4-9 7. To uninstall RAIDWatch choose the uninstall icon in the RAIDWatch group. 4.6 Audible Alarm Whenever any of the threshold values assigned to the different controllers are violated or when an active device in the controller head fails, an audible alarm will be triggered. To determined what has triggered the alarm the user will have to read the error message on the LCD screen or on the PC terminal. WARNING: If an alarm is triggered it is necessary for the user to determine the problem. If the audible alarm is ignored or not taken seriously and the problem is not rectified, permanent damage to the system can result. 4.6.1 Default Threshold Values The following table shows the default threshold values for the ER2510FS RAID Controller Head. If any of these values are surpassed the alarm will sound: Upper Threshold Lower Threshold +3.3V +3.6V +2.9V +5V +5.5V +4.5V +12V +13.2V +10.8V CPU Temperature 90ºC 0ºC Board Temperature 90ºC 0ºC Table 4-1: - Default Threshold Values 4-10 Monitoring The System The thresholds in the above table are the default threshold values. The user can change these values. To see how to change these values please refer to the Generic Operation Manual that came with your system. 4.6.2 Failed Devices If any of the following devices fail the audible alarm will be triggered. • RAID Controller Modules • Cooling Fan Modules • PSU Modules • BBU Modules 4.7 SES Monitoring The ER2510FS RAID Controller Head supports SES. SES is a command set that is used to manage and sense the state of the power supplies, cooling devices, temperature sensors, individual; drives, and other non-SCSI elements installed in a fibre channel JBOD enclosure. If you have a SES-compliant enclosure the firmware on the controller boards will be able to decode and report this information. NOTE: The SES monitoring support assists users in determining where a fault may or may not exist within an external enclosure. If there is a fault in the enclosure please contact the enclosure manufacturer to solve the problem. 4.7.1 Using Terminal Emulation 1. Open the PC Terminal Emulation screen. Enter the Main Menu and, using the arrow keys, scroll down the menu and select the Monitoring The System 4-11 “View and Edit Peripheral Devices” option.

It also introduces basic information about fibre channel cables and introduces fibre-to-fibre topologies. Three sample topologies are outlined. The user can set their system up using these topologies or use them as a guide for developing their own unique topologies. 5.2 Basic Configuration Rules When you are configuring your storage subsystem, the following are some basic rules that should be followed. NOTE: Please adhere to these basic configuration rules. They are provided for your convenience to ensure that your storage system will run smoothly and effectively. • When selecting the number of hard drives that should be connected through the drive channels, the transfer rates and the mechanical performance of the hard disks should be considered. Configurations and Topologies 5-1 • When cabling, follow all the fibre channel specifications. Pay attention to signal quality and avoid electronic noise from adjacent interfaces. • The drives in the same logical array should have the same capacity, but it is preferred that all the drives have the same capacity. • A spare should have a minimum capacity that is equivalent to the largest drive that it is expected to replace. If the capacity of the spare is less than the capacity of the drive it is expected to replace then the controller will not proceed with the failed drive rebuild. 5.3 Fibre Channel Cables NOTE: Fibre Channel cables are expensive components that need to be purchased separately. These cables are sensitive and should not be bent as they are susceptible to damage. 5.3.1 Fibre Channel Speed Detection Speed auto-detection is specified by the Fibre Channel standard. If a 1Gb/s port is connected to a 2Gb/s port, it will negotiate down and run at 1Gb/s. If there are two 2Gb/s ports on either end of the link the link will be run at 2Gb. NOTE: 1. For the Type-1 IO modules, users have to manually select the fibre channel speed of the IO module using a jumper. Please refer to chapter 3 to see how this is done. 2. 5-2 If the fibre channel cable that is being used is too long your system may end up running at 1Gb/s even with two 2Gb/s ports. Configurations and Topologies 5.3.2 Choosing the Fibre Cables The Fibre Channel Standard allows for both copper and optical connections. Copper cables are cheaper but limited to lengths of less than 30m. Optical cables can be used over longer distances and have been shown to be more reliable. Due to the extremely high data transfer rates, optical cables are preferred for 2Gb/s fibre connectivity. Optical cables are also less susceptible to EMI. 5.3.3 Lasers WARNING: Lasers can cause permanent eye damage, which may result in permanent blindness, and therefore must be treated with respect and used with caution. Never look at lasers without knowing whether they are on or off is hazardous. Wavelengths: - The lasers on fibre channel fiber optic cables emit either short wave (SW) beams (770nm – 860nm) or long wave (LW) (1270 nm - 1355 nm) beams. Cables that use either of these wavelengths can be used on the ER2510FS controller head. Laser Types: - Two type of laser devices can be used in fibre cables: Optical Fibre Control (OFC) and non-OFC lasers. The OFC lasers are high-powered and can be used over long distances. Safety features: - OFC lasers, due to their high power output, usually come with a safety mechanism that switches the laser off as soon as it is unplugged. Non-OFC lasers do not (due to their low power) come with these safety features but they can still inflict damage. 5.3.4 SFP Transceivers Once you have purchased your fibre channel cables, it may be necessary to connect them to small form factor pluggable (SFP) transceivers. These transceivers should typically have at least 2Gb/s Configurations and Topologies 5-3 bi-directional data links, a laser transmitter (for fiber optic cables), LC connector and a metal enclosure to lower the EMI. NOTE: LC connectors are small form factor, fiber-optic connectors based on a 1.25-mm ceramic ferrule and the familiar latching mechanism of the RJ-45 modular plug and jack. Other beneficial features for a typical SFP transceiver include a single power supply and low power dissipation. It is also preferable that these transceivers are hot-swappable. It is also important that any transceiver you use meets the Fibre Channel Performance and reliability specifications. NOTE SFP Modules must be purchased separately. Please purchase the correct SFP modules from your ER2510FS Controller Head vendor/distributor. 5.4 Fibre Topologies The ER2510F RAID Controller head uses up to two fibre controllers for the RAID subsystem. The Fibre Channel Standard has been designed to support three separate topologies. They are point-topoint, FC-AL and fabric switch topologies. 5-4 • Point-to-Point: Point-to-point topology is the simplest topology that can be used. It is a direct connection between two fibre channel devices. • FC-AL: This is the most common topology currently in use. Fibre channel devices are all connected in a loop. Each device is assigned an arbitrated loop physical address (AL_PA). The FCAL is able to support 127 devices in a single loop. Configurations and Topologies • Fabric: The fabric topology can support up to 224 fibre channel devices. This topology allows many devices to communicate at the same time. To implement this topology a fibre switch is required. 5.4.1 Host Side Topologies The Host Channels of the ER2510F RAID Controller head supports all three topologies described above. The primary concern for configuring host-side topologies is that points of failure are avoided. It is therefore recommended that the host side be connected to at least two HBAs. It is also preferable to connect the RAID subsystem to the host computer(s) through either a fibre channel hub or a fibre switch. In the configuration examples given below, all the host channels are connected to HBAs. It is also possible to connect the host channels to fabric switches. NOTE: To create dual redundant data paths on the host side, it is necessary for failover software to be installed on the host computer. 5.4.2 Drive Side Topologies The drive side channels support FC-AL topologies. It is recommended that you use an FC-AL topology with your harddrives as this will allow you to use and manage more storage space. The drive channels can be connected directly to a JBOD or through a fibre hub to a JBOD. It is also recommended to connect two channels to each JBOD. This will ensure full data path redundancy. If one data path is disconnected, damaged or destroyed the second data path will inherit the workload.

Configurations and Topologies 5-9 • Both controllers must be using an identical firmware version. 5.6.1 Redundant Controller Modes Two different redundant controller modes are supported: the activeto-standby and the active-to-active mode. • Active-to-standby: If this redundant controller mode is employed then one controller, the primary controller, does all the work while the other controller, the secondary controller, waits for the primary to fail. If, and when, the primary controller fails the secondary controller will take over the operation of the RAID subsystem. • Active-to-active: This redundant controller mode allows the workload to be shared between the two controllers. This will increase the operating speed of the system and allow the full potential of both controllers to be exploited. If one controller fails the second controller will take over the entire workload. 5.6.2 Internal Connections The two controllers are connected to each other internally through the Mid-Plane board. This enables the two controllers to synchronize their caches and distribute the workload between the controllers. The drive channels are also connected internally, via the mid-plane board, to both controllers. This enables the correct distribution of load traffic. 5.6.3 Unique Identifier The Unique Identifier is a user specified 16 bit, hexadecimal number that is used to assign a fibre channel port number to the primary controller. Each controller is assigned a separate hexadecimal number. The firmware then determines which Unique Identifier to use. To see how to use the front panel LCD screen or the terminal 5-10 Configurations and Topologies emulation program to enter the unique identifier, please refer the Generic Operation Manual. 5.6.4 Redundant Controller Configurations • Channel Mode:- Every fibre channel can be configured as a drive or host channel manually. There is no limit to the number of drive or host channels that should be configured in the system. Therefore in the ER2510FS-6 RAID Controller Head, there maybe as many as five drive channels and one host channel or as many as five host channels and one drive channel. Channel 0 and 1 are, by default, host channels. • ID/LUN Mapping:- I/O load distribution is determined by the Host ID/LUN mapping. Different logical groups of drives are mapped to the LUN numbers under a host ID. For a multi-host operation, a logical drive configuration can be mapped to different ID/LUN combinations. In this case the File locking mechanism is necessary. ID/LUN Mapping procedures are described fully in the Generic Operations Manual.

The ER2510FS is a modularized RAID management subsystem and is therefore easy to maintain and upgrade. NOTE: A complete list of the spare parts that are available for the ER2510FS RAID Controller Head models can be found in Appendix E. 6.2 System Maintenance If any of the active components on the ER2510FS RAID Controller Head fails they need to be replaced. If the system is connected in a fully redundant configuration then it is possible to hot-swap all of the items. If the active components are not in a redundant configuration then it is necessary to turn the system off to replace the failed component. 6.2.1 PSU The PSUs are preinstalled components and are located at the back of the ER2510FS RAID controller head on the left-hand Maintaining and Upgrading 6-1 side.

Some of these features enhance the performance of the system, other features add configuration flexibility and other features simplify the installation, maintenance and upgrade procedures of the system. This section highlights some of the features of the ER2510FS RAID Controller Head. A.2 Flexible Configuration Options A.2.1 Four Models The ER2510FS RAID Controller Head comes in four different models. This provides users with extreme configuration flexibility and enables them to customize their systems to meet their unique and specific needs. Differences between the models include different controller configuration modes, the number of available fibre channels and the IO module type. Table A-1 lists the four different models and briefly summarizes their differences. System Features A-1 MODELS CONTROLLER MODE CHANNELS (Controller Model) ER2510FS-4S Single controller 4 Fibre 1 x IFT5251F-4 ER2510FS-6S Single controller 6 Fibre 1 x IFT5251F-6 ER2510FS-4RH Dual-Redundant controllers 4 Fibre 2x IFT5251F-4 ER2510FS-6RH Dual-Redundant controllers 6 Fibre 2x IFT5251F-6 Table A-1: ER2510FS Model Variations A.2.2 Front Panel Variations To facilitate the use of two different IO Modules on the front panel two different front panels have been developed. A.2.3 Fibre Channel Configuration All the ER2510FS RAID Controller Heads come with a minimum of four and a maximum of twelve 2Gb/s fibre channels. All the channels can be configured as either host or drive channels. The host channels support point-to-point, fibre switch and fibre channel arbitrated loop (FC-AL) connectivity, and are therefore able to connect to the Host Bus Adapter (HBA) through either a Hub or a Fabric Switch. The drive channels all support both point-to-point and FC-AL connectivity. A.3 RAID Support and RAID Levels The ER2510FSRAID Controller Head comes with a minimum of one and a maximum of two IFT5251F-4 or IFT5251F-6 RAID Controllers. Both models are 2Gb/s fibre channel controllers and are A-2 System Features designed to provide RAID level 0, 1 (0+1), 3, 5, 10, 30, 50, or JBOD RAID storage. A.3.1 Non-RAID Storage One common option for expanding disk storage capacity is simply to install multiple disk drives into the system and then combine them end to end. This method is called disk spanning. In disk spanning, the total disk capacity is equivalent to the sum of the capacities of all fibre drives in the combination. This combination appears to the system as a single logical drive. Thus, combining four 1GB fibre drives in this way, for example, would create a single logical drive with a total disk capacity of 4GB. Disk spanning is considered non-RAID due to the fact that it provides neither redundancy nor improved performance. Disk spanning is inexpensive, flexible, and easy to implement; however, it does not improve the performance of the drives and any single disk failure will result in total data loss. 2 GB Hard drive + 3 GB Hard drive + 1 GB Hard drive + 2 GB Hard drive = Logical Drive 2 + 3 + 1 + 2 = 8 GB Logical Drive Figure A-1: - Non-RAID System Features A-3 A.3.2 JBOD JBOD stands for Just a Bunch of Drives. The controller treats each drive as a stand-alone disk, therefore each drive is an independent logical drive. JBOD does not provide data redundancy. 2 GB = 2 GB Har d Dr i ve Logi c al Dr i ve 3 GB = 3 GB Har d Dr i v e Logi c al Dr i ve 1 GB = 1 GB Har d Dr i ve Logi c al Dr i ve 2 GB = 2 GB Har d Dr i ve L ogi cal Dr i v e Figure A-2: - JBOD A.3.3 RAID 0 RAID 0 implements block striping where data is broken into logical blocks and striped across several drives. Although called “RAID 0,” this is not a true implementation of RAID because there is no facility for redundancy. In the event of a disk failure, data is lost. In block striping, the total disk capacity is equivalent to the sum of the capacities of all fibre drives in the array. This combination of drives appears to the system as a single logical drive. RAID 0 provides the highest performance without redundancy. It is fast because data can be simultaneously transferred to/from multiple disks. Furthermore, read/writes to different drives can be processed concurrently. A-4 System Features Logical Drive Physical Disks Block 1 Block 2 Block 3 Block 4 Block 5 Block 6 Block 7 Block 8 . . Striping Block 1 Block 2 Block 3 Block 5 Block 4 Block 6 Block 7 . . Block 8 . . Figure A-3: - RAID 0 A.3.4 RAID 1 RAID 1 implements disk mirroring where a copy of the same data is recorded onto two sets of striped drives. By keeping two copies of data on separate disks or arrays, data is protected against a disk failure. If, at any time, a disk on either side fails, the remaining good disk (copy) can provide all of the data needed, thus preventing downtime. In disk mirroring, the total disk capacity is equivalent to half the sum of the capacities of all fibre drives in the combination. Thus, combining four 1GB fibre drives, for example, would create a single logical drive with a total disk capacity of 2GB. This combination of drives appears to the system as a single logical drive. NOTE One drawback to RAID 1 is that it does not allow running expansion. Once a RAID 1 array has been created, to expand it, the data must be backed up elsewhere before a new drive can be added. Other RAID levels permit running expansion. RAID 1 is simple and easy to implement; however, it is more expensive as it doubles the investment required for a non-redundant disk array implementation.

Figure A-4: - RAID 1 In addition to the data protection RAID 1 provides, this RAID level also improves performance. In cases where multiple concurrent I/Os are occurring, these I/Os can be distributed between disk copies, thus reducing total effective data access time. A.3.5 RAID 1(0+1) RAID 1 (0+1) combines RAID 0 and RAID 1 – mirroring and disk striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard disk drives. If more than two hard disk drives are chosen for RAID 1, RAID (0+1) will be performed automatically.

Figure A-5: - RAID 1(0 + 1) IMPORTANT: RAID (0+1) will not appear in the list of RAID levels supported by the controller. If you wish to perform RAID 1, the controller will determine whether to perform RAID 1 or RAID (0+1). This will depend on the number of drives selected for the logical drive. A.3.6 RAID 3 RAID 3 implements block striping with dedicated parity. This RAID level breaks data into logical blocks, the size of a disk block, and then stripes these blocks across several drives. One drive is dedicated to parity. In the event a disk fails, the original data can be reconstructed from the parity information. In RAID 3, the total disk capacity is equivalent to the sum of the capacities of all fibre drives in the combination, excluding the parity drive. Thus, combining four 1GB fibre drives, for example, would create a single logical drive with a total disk capacity of 3GB. This combination appears to the system as a single logical drive. RAID 3 provides increased data transfer rates when data is being accessed in large chunks or sequentially. However, in write System Features A-7 operations that do not span multiple drives, performance is reduced since the information stored in the parity drive needs to be recalculated and re-written every time new data is written to any of the data disks.

This RAID level offers the same redundancy available in RAID 3; though the parity information this time is distributed across all disks in the array. Data and relative parity are never stored on the same disk. In the event a disk fails, original data can be reconstructed using the available parity information.

Block 7 Block 8 . . Figure A-7: - RAID 5 RAID 5 offers increased data transfer rates when data is accessed in large chunks (i.e., sequentially) and reduced data access time for many simultaneous I/O’s when they do not span more than one drive. A.3.8 Spares RAID implementations include one other basic concept that needs to be introduced at this point: spare drives. RAID levels that have redundancy, levels 1, 3, and 5, all allow users to include a drive as a “spare.” Spare drives are installed, fully functioning, “hot-ready” hard drives which a RAID controller will use to replace a failed drive as soon as the failure is detected. The purpose of this, obviously, is to enhance the existing fault-tolerant capabilities of a RAID array. A.4 Redundant Features A.4.1 Dual-Active Redundant Controllers The ER2510Fcontrollers can be configured in a dual-active redundant mode. If one controller fails the other controller will System Features A-9 automatically take over the workload of the failed controller and manage the entire storage system. Both the cache writes and configuration data are fully synchronized. Failover and failback operations are completely transparent to the host and IOs are moved between the controllers without any user intervention. A.4.2 Redundant Data Paths Dual data paths can be connected to the JBOD enclosure/HBA from the ER2510FS RAID Controller Head. If one data path should fail the data can be transmitted through the alternative data path. Full host side redundancy can be achieved if two host channels are connected to two separate HBAs and then to the Host computer. A.5 Fault Tolerance A.5.1 Hot-swappable active components All the active components; including the controller modules, power supply units (PSU), the IO modules, the battery back up units (BBU), the maintenance modules and the LED modules; are hotswappable. If any of these components fail, they can be replaced without turning off the system or disrupting the smooth operation of the system. A.5.2 Global and Local Spares Both Global and Local (dedicated) spares are supported. The controller(s) will automatically disconnect from a failed drive and start to rebuild data on the spare drive. The spare drive will then replace the failed drive. A.5.3 Hot-Swapping of Drives A failed drive in the JBOD storage enclosure can be exchanged without turning off the system or interrupting the smooth operation A-10 System Features of the system. Once the failed drive is replaced the data will be rebuilt in the background. Hot-swapping is supported through the automatic disconnection from a failed drive and the detection of a reserve drive. All these failure recovery procedures are completely transparent to the host. A.5.4 S.M.A.R.T. Support S.M.A.R.T (Self Monitoring Analysis and Reporting Technology) is supported with configurable reaction schemes. Users may select different reaction schemes for immediate prevention against S.M.A.R.T. detected errors. Available options include: detect only, clone and replace, and perpetual clone. A faulty drive can be cloned to an active spare upon the discovery of errors. A.5.5 Other Fault Tolerant Features Other comprehensive failure management ER2510FS RAID Controller Head include: features on the • Automatic Bad Block Assignment • Background rebuilding • Verify-after-Write is supported on normal writes, rebuild writes and/or RAID initialization writes. • Regeneration of parity of logical drives in the background. A.6 SAN Features A.6.1 Logical Unit Numbers Up to 128 Logical Unit Numbers (LUNs) are supported. Each LUN can be mapped to a logical unit (drive or volume). The LUN provides the logical unit with a unique signifier which enables the controllers to identify it. System Features A-11 A.6.2 LUN Masking Both the IFT5251F-4 and IFT5251F-6 RAID Controllers support LUN Masking. This enables a specific LUN to be uniquely assigned to a specific host. The host will then only be able to access the LUNs which are assigned to it, all the other LUNs will be “hidden”. A.7 Mechanical Features A.7.1 Modular Design The modular design of the ER2510FS simplifies the installation process and makes these systems easy to upgrade and maintain. All the active components are modular and are therefore easy to replace. A.7.2 Hot-swap mechanisms Special hot-swap mechanisms have been designed to facilitate the easy removal and replacement of the hot-swappable active components. A.7.3 Cableless Design All the active components are cableless. This simplifies the installation of the system. Users do not have to be concerned with connecting any cables. A.7.4 Slide rails and support handles Both support slide rails and support handles can be used to mount the system into a standard Cabinet. The slide rails and handles ensure simplified installation and solid support. A-12 System Features A.7.5 Dummy Canisters and Brackets The ER2510FS comes in four different models. Some of these models come with only four IO modules and one controller module. To ensure the smooth running of these systems, dummy canisters and brackets have been designed. Once installed, these dummy canisters and brackets will ensure that the air impedance within the chassis is properly regulated and the system cooled sufficiently.
