EonStor U16U Series
U160 SCSI-to-SCSI RAID Subsystem Up to 1024 LUNs per controller, and 64TB per logical drive are supported. Drives on different channels or different enclosures can be selected to compose a logical configuration, reducing the chance of downtime by hardware failure.

OVERVIEW The EonStor U16U stands for the highest performance standard made available through Infortrend's sophisticated RAID technologies. Boasting a highperformance XOR engine and the complete firmware functionality, the U16U is ideal for mass scale storage using SCSI drives. The series enclosures come with redundant, load-sharing power supplies, and multiple cooling fans. Critical modules are hotreplaceable. Adding to an array's availability and manageability, the series is provided with the most flexible options with system monitoring. System managers can rectify and be alerted of a system event locally through fault indicators, remotely through GUI icons in the RAIDWatch manager, the array-independent Event Monitor, via email, SNMP traps or LAN broadcast by NPC (Notification Processing Center).

Architecture The subsystem series is specialized for flexible resource utilization to manage various-size IOs, random, or sequential access that requires high-speed throughput. A range of 4 to 256KB array stripe-size and optimization parameters are adjustable on a per logical drive basis. With the help of a dedicated XOR and an L2-enabled CPU, IOs are rapidly distributed between host and drives. The RAID controllers in the subsystem come in the 4 or 6channel version. The system using the 6-channel controllers allows cascading with a JBOD to scale capacity.
Firmware Capabilities Designed for the heterogeneous and multi-host environments, the system supports up to 128 logical drives, 32 logical volumes, and each of the logical drives can be partitioned into 64 storage sections. Each of the individual sections can be made available with independent Host LUNs.
Firmware provides numerous options that help to achieve the highest level of data availability and performance. In addition to the full-featured RAID and Recovery functionality, it is able to manage imminent causes of data loss, even those not directly related to RAID. Automatic disk media scan can be carried out on a preset schedule to prevent the situation when parity is damaged due to the block errors across multiple drives. Even if this happens, firmware is able to salvage most data by skipping unrepairable data blocks. Other integrity options include: SMART support with configurable rebuild schemes, clone failing drive, automatic reassignment of bad sectors, parity regeneration, and verification on writes.
Scalability Array capacity can be expanded online by adding drives or replacing the original drives with drives of larger capacity. Arrays can be expanded without additional enclosures or powering down the system.
Manageability
SPECIFICATIONS
The Java-based RAIDWatch GUI manager provides easy-to-use interfaces, is rich in configuration options, and requires only a web browser to remotely manage their storage over a network. Its submodules, Event Monitor and NPC, allow system managers to rectify a problem by its graphical presentations and a variety of notification methods.
Enclosure type
Enclosure Management The RAID enclosure or its cascaded JBOD is monitored through an I2C bus. An added enclosure is immediately brought online and made visible through the graphical GUI interface. On occasions like low battery charge, UPS AC loss, fan failure, or high temperature, an automatic cacheflush will be initiated. When enclosure or board temperature exceeds preset thresholds, system will shut down to protect being damaged.
