Chapter 1 Overview This chapter introduces the features and capabilities of ExaRAID HD. The ExaRAID HD disk array provides superior functionality and performance for managing your information. The ExaRAID HD disk array offers the following models: A12S-PA 12 bay disk array operated by a single RAID controller. A16S-PA 16 bay disk array operated by a single RAID controller. A16D-PA 16 bay disk array operated by dual independent RAID controllers. A24S-PA 24 bay disk array operated by a single RAID controller. A24D-PA 24 bay disk array operated by dual independent RAID controllers. With a Java based GUI, the RAIDGuard X Server and Client software offers improved functionality and manageability. Using the latest Intel XScale® 64-bit RISC processor, ExaRAID HD supports up to 24 x SATA I/II disk drives, making it ideal for applications that require high storage capacity and fast access such as video editing, digital surveillance, file servers and shared storage. Using intelligent I/O processing and elaborate algorithms, ExaRAID HD bypasses slow disk drives and rebuilds the data by sustaining a stable throughput and streamlining the data transfer, therefore enabling the smooth handling of heavy loaded and time critical applications. Data protection is one of the key features of ExaRAID HD. Online recovery and reallocation protect against disk failure and bad sectors. Disk scrubbing is available to fix the bad sectors and online data, and parity refresh protects against data loss caused by media aging. The RAIDGuard X management software supports the online changing of RAID configurations and quick configuration on any Java enabled platform. Together with the next generation BIOS and Windows Storport driver, its future is guaranteed. 6 Chapter 1 – Overview Key Features ExaRAID HD features the following: z z z z z z z z z z z z z z z z z z z z z z z z z z z z z Multiple RAID levels: 0,1, 0+1, 5, 6, and JBOD Up to 4 independent disk arrays Supports 12, 16, and 24 SATA I/II drives RAID capacity partitioning: up to 16 slices Supports up to 64 LUNs Variable stripe sizes, up to 256KB Selective initialization method with on-the-fly background initialization and performance evaluation Supports over-2TB volumes Online RAID group expansion Online RAID level migration On-the-fly RAID initialization Snapshot for fast backup and restore Supports write-back and write-through caching Selective and adaptive read/write optimization policies Fast read response by intelligently bypass slow drive Automatic drive insertion/removal detection and fast disk rebuilding Online bad block data recovery and reallocation Online disk scrubbing with data refresh and parity regeneration Disk health monitoring by S.M.A.R.T.

Serial ATA (often abbreviated as SATA or S-ATA) allows data transfer up to 3 Gbps and is compatible with older Parallel ATA standards. It has an additional advantage parallel ATA in that cables are thinner, so airflow within computer cases is less impeded, and can extend to one meter in length (against only 40 cm for parallel ATA). PCI EXPRESS X 4 Developed by Intel in 2004, PCI Express has been developed to match the speed of CPUs. It provides a serial communications channel that provides up to 2.5 Gbits/sec in each direction of a pair of wires. The 4 refers to the number of pairs of wires, therefore allowing a maximum of 10 Gbits/sec transfer. FIRMWARE Appropriate firmware must be loaded into the Re-drive card for it to function. The ExaRAID HD disk array is shipped with firmware preloaded. Check the installation disk that came with the package to find a backup firmware copy. You can also periodically check the vendor’s web site to find the latest firmware version for use with the Re-drive card. BIOS and EFI The ExaRAID HD Re-drive card contains an internal BIOS and EFI, which can be used to configure a RAID array instead of using the RAIDGuard X GUI. The BIOS and EFI are accessed as the Re-drive card boots up and contains all the functionality of the RAIDGuard X GUI. The BIOS and EFI may be upgraded using the RAIDGuard X GUI. See www.accusys.com.tw for upgrades. 8 Chapter 2 – Package Contents Chapter 2 Package Contents This chapter provides a checklist for ExaRAID HD package contents.

If your disk array is managed by dual controllers and you wish to install a second BBM, repeat steps 1 to 8 for controller B. Install only battery backup modules manufactured by Accusys. Use of battery cells from another source may damage the disk array and void your warranty. 36 Chapter 4 – Installation Upgrading to Dual Independent Controllers You can upgrade your disk array from a single controller to dual independent controllers. Before you upgrade, you will need to backup data stored on the hard disk drives and delete the current arrays. All data will be lost when the current arrays are deleted. Once the second controller is installed, you can retrieve the stored data and create new arrays for each controller. When you upgrade to dual independent controllers, you will need to install controller B into the chassis, and AA-MUX adapters to the disk trays. The AA-MUX adapter enables the dual independent RAID controller technology. You must purchase controller B, AA-MUX tray adapters, adapter brackets, and adapter screw packs separately. Contact your vendor for details. The AA-MUX adapter must be installed to the disk tray before you can reinstall a SATA I/II hard disk drive. To insert controller B: 1. Loosen the screws of the blanking board over the controller B slot. 2. Remove the blanking board. 3. Keep the handle lifted as you insert the new controller into the controller B slot. 4. Push the handle down to lock the controller into place. 5. Tighten the screws. To install the AA-MUX adapters to the disk trays: 1. Loosen the screws of the disk tray and remove the HDD. 2. Secure the AA-MUX adapter to the bracket with two screws. 3. Align the AA-MUX adapter with the end of the disk tray and secure with four screws. 4. Insert the HDD into the disk tray, with the connectors facing the AA-MUX adapter. 5. Slide the connectors into place. 6. Secure the HDD to the disk tray with four screws on the bottom of the disk tray. 37 ExaRAID HD User’s Manual Upgrading Memory You can upgrade the memory of the RAID controller for faster and more efficient performance. The RAID controller supports up to 2GB memory. 1. Loosen the screws of the controller. 2. Lift up the handle to release the controller, and gently pull it out. 3. Pull the white retaining chips on either side of the memory card to release it. 4. Insert the new memory card gently but firmly, until the retaining clips click into place. 5. Keep the handle lifted as you insert the controller back into the slot. 6. Push the handle down to lock the controller into place. 7. Tighten the screws. 38 Connections 39 ExaRAID HD User’s Manual Chapter 5 Connections This chapter provides instructions for making connections and powering on your disk array. After you have installed the necessary components, your disk array is ready to be connected and powered on. Connecting to the Host Server z Insert one end of the external PCIe x4 cable into the external PCIe x4 port on the back of the disk array, and the other end into the external PCIe x4 port of the host server. Do NOT remove the external PCIe x4 cable when in use as this will cause data loss. 40 Chapter 5 – Connections Removing the External PCIe x4 Cable z Put your finger into the ring of the external PCIe x4 cable connector and pull gently to release it. Do NOT remove the external PCIe x4 cable forcibly in any other way, as this will damage the cable. Connecting to a Power Source and Powering On 1. Plug the power cables into the power sockets on the back of the disk array, and connect the other end to a power source. 2. Press the power switch on the back of the disk array. To power on A12S-PA, press both power switches on the back of the disk array. Before powering on, make sure the hard disk drives, controller(s), Re-drive card, external PCIe x4 cable(s), and power cables are properly installed and connected. 41 BIOS and LCD Menu 42 Chapter 6 –Configuring the BIOS Chapter 6 Configuring the BIOS This chapter provides instructions for creating the first disk array with the BIOS, and a menu tree detailing the structure of the BIOS. The BIOS functionality is similar to that of the RAIDGUARD X application. You can use the BIOS to configure your disk array. Entering BIOS 1. Start the server and watch the screen. When it gets to the position shown below, press Enter. 2. Enter the password and press Enter. The default is 00000000 (8 zeros). 43 ExaRAID A12S-PA, A16x-PA, A24x-PA User’s Manual Quick Array Configuration 1. For first time use, the quick array configuration option is recommended. Select RAID Configuration > Config Array > Quick Array Configuration, and the RAID level.

If there are only 2 disks installed, the default RAID array is R0 (striping). 2. If there are more than 2 disks installed, the default RAID array is R5 (data protection). 44 Chapter 6 –Configuring the BIOS Custom Array Configuration 1. To manually enter the details for creating a new array, select RAID Configuration > Config Array > Custom Array Configuration. You must create Array 1 before you can create others. 2. Press Enter. 3. 4. 5. 6. 7. Select the RAID level between 0, 1, 5, 6, 0+1, and JBOD. Select the initialization type. On-the-fly is recommended as it contains parity. Select the stripe size. Select the drives to include in the array. XX indicates a hard disk drive can be added Use the up or down arrow to go to CREATE and press Enter. The array is created. 45 ExaRAID A12S-PA, A16x-PA, A24x-PA User’s Manual BIOS Menu Structure The BIOS menu structure details how the commands in the BIOS relate to each other. The BIOS manages the same information as the RAIDGuard X application. See the RAIDGuard X User's Manual for further details on these functions. 46 Chapter 6 –Configuring the BIOS BIOS Menu The table below provides an overview of the BIOS menu functions. See the RAIDGuard X User's Manual for further details on these functions. RAID Config Utility Config Array Quickly create an array, administer the details of a current array, or configure a JBOD. View a collection of disks from one or more commonly accessible disk controllers, presented as one or more virtual disks. Set Slice Add and delete slices. Unlike striping, slicing allows the creation of arrays from a single disk without loss of speed as the disk fills up. This is because when striping across disks, the center of the disk fills up; when it’s being written to, it slows down. Slicing creates new disk partitions with similar characteristics, therefore keeping the speed the same. LUN and Map Display details and set LUNs and Maps. A LUN (Logical Unit Number) is a unique identifier used on a SCSI bus that enables it to differentiate between up to eight separate devices (or logical unit). Each LUN is a unique number that identifies a specific logical unit, which may be an end user, a file, or an application. Locked Disk Unlock locked disks. Disks that have become locked due to an error can be unlocked. Array Information Display the RAID level, initialization type, stripe size, number of disks, and memory capacity of the array. Refresh Array Refresh an array to improve performance. RAID Checking Check that the RAID is functioning correctly. RAID Expansion Expand the disks of an array. When extra disks are added to the chassis, the number of disks in an array can be expanded without needing to reconfigure the entire array. RAID Migration Migrate an array from one RAID type to another. For example, from RAID 5 to RAID 1. Disk Configuration Utility Automatic Detection Detect installed disks. A new disk must be detected before it can be added to an array. Disk Information Display manufacturer and speed details of the installed disks. 47 ExaRAID A12S-PA, A16x-PA, A24x-PA User’s Manual Controller Configuration Utility Password Change Change the BIOS password. Serial Number Display the serial number of the Re-drive card. System Cache Activate and disable the system cache. Controller memory is used to speed up data transfer to and from a disk. Disk Cache Activate and disable disk caching. Controller memory is used to speed up data transfer to and from a disk. Disk Lag Proof Activate and disable disk lag proof mode. Disk Lag Proof ensures streaming continuity and lossless recording. Legacy RAID algorithms read only data stripes and wait for slow reads. It reads parity stripe and regenerates only when read fails. NCQ Mode 48 ExaRAID HD reads both data and parity stripes concurrently. It bypasses the slow reads and returns data to host by the regenerated data. Activate and disable NCQ mode. NCQ allows several outstanding commands to be given to the drives at one time. The commands are carried out in sequence instead of the order they are given, rather like pressing buttons in a lift; the lift goes to the next floor in the list, not in the order that the buttons are pressed. This speeds up the disk access and reduces the load on the drives. Chapter 6 –Configuring the BIOS On-The-Fly Legacy RAID algorithms only record the progress. Sectors that have been initialized might have to be initialized again and accessed with resync overhead. ExaRAID HD records the initialized sectors in bitmap. All sectors are initialized only once. The whole initialization will be done faster and performance will be better during the initialization. Synchronize Cache Mode Activate and disable synchronize cache mode. Real Time Clock Display and set the BIOS clock. S.M.A.R.T. Activate and disable S.M.A.R.T. warnings and polling frequency. Max pre-fetch number Set the maximum number of stripes that can be pre-fetched by the array. Controller information Display the model name, memory size, and system, boot, BIOS and EFI versions. About Display the company information. Exit Exit the BIOS. 49 ExaRAID A12S-PA, A16x-PA, A24x-PA User’s Manual Chapter 7 Configuring the LCD Menu This chapter introduces the ExaRAID HD LCD panel, and provides instructions for using the LCD menu to create an array.
