Specifications

RAID
  1. Multiple arrays configurable with dedicated or global hot spares
  2. RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, and NRAID
  3. Online expansion by
    1. Adding new drives
    2. Copying and replacing drives with drives of larger capacity
  4. Automatic background rebuild
  5. Configurable stripe size and write policy per array
  6. Intelligent Drive Handling
    1. In degraded mode: Skipping irreparable blocks to continue rebuild
    2. In normal operation: Data block verification and repair
System Components

Redundant, hot-swappable components, designed for no single point of failure

  1. 3U RAID enclosure
  2. Single RAID controller
  3. 16 drive trays
  4. Dual redundant power supplies
  5. 2 hot-swappable fan modules
Management
  1. Firmware-embedded Java-based GUI RAID manager
  2. Centralized management of multiple arrays over in-band or Ethernet
  3. Real-time event notification over Email, LAN broadcast, or SNMP traps
  4. Host-side SES emulation with pass-through to back-end I2C SES emulation
  5. SNMP 2.0 MIBs with get and set commands
  6. Firmware-embedded utility via LCD keypad or RS-232C port
Drive Interface
  1. 3.5", 1" high 1.5Gbps SATA disk drives
  2. 16 hot-swappable drive trays
  3. Automatic bad sector reassignment
  4. Drive hot-swappable via SCA-II connectors
  5. Dedicated bandwidth to each connected drive
Host Interface
  1. FC-AL, point-to-point, and switched fabric
  2. Up to 1024 LUNs if sufficiently large memory is used with the proper settings
  3. Concurrent I/O commands
  4. Tagged Command queuing up to 256
  5. Variable stripe size per logical drive
  6. Optimization setting for random or sequential I/Os
Maintenance & Availability
  1. Optional Li-ion battery support
  2. Immediate array availability
  3. Drive roaming, array configuration on drives
  4. Controller voltage and temperature self-diagnostics
  5. Auto switch cache policy and Auto shutdown
  6. When a RAID controller detects conditions exceeding preset thresholds, the following actions will be exerted to protect the hardware:
    1. Automatically flush cached data and switch the array’s caching mode from write-back to write-through
    2. Commence an auto shutdown

What is remarkable is all environmental thresholds associated with this mechanism are user-configurable and that caching mode changes back to write-back once normal condition is restored.
