Management
  1. Front LCD control panel for setup and configuration
  2. 10/100 BaseT Ethernet for out-of-band management
  3. RS-232C for local access to firmware-embedded utility
  4. Firmware-embedded, Java-based RAIDWatch® GUI manager

  11. SNMP trap event notification with plain-text event message (no MIB file required)
  12. SNMP V2.0 MIB file support with get-and-set commands
Indicators
  1. Onboard alarm is triggered when one of the following modules fails:
    1. RAID controller module
    2. Cooling module
    3. Power supply unit
    4. Hard drive
  2. Configuration Client for real-time event notification over email, Fax, LAN broadcast, MSN messaging, ICQ, or SNMP traps
  3. Module status LED indicators:
    1. Two (2) per drive tray
    2. One (1) per power supply unit
    3. Three (3) per LCD panel
    4. Five (5) per RAID controller module
    5. Two (2) per RJ-45 Ethernet connector
    6. One (1) per optional BBU module
  4. Module failure alert through I2C bus
  5. Auto Switch Cache Policy and Auto Shutdown
  6. When a RAID controller detects conditions exceeding preset thresholds, the following actions are initiated to protect the hardware:
    1. Cached data is automatically flushed and the array’s caching mode switches from write-back to write-through mode.
    2. If conditions persist past the preset period of time, auto shutdown of the controller will commence.
  7. All thresholds associated with this mechanism are user configurable and, once a subsystem manager restores the normal operating conditions, the caching mode reverts from write-through to write-back mode.
Intelligent Drive Handling

If two bad blocks occur on two member drives of an array, the integrity of the stored data is endangered. Media Scan, Infortrend’s innovative intelligent drive handling function, retrieves data from the damaged sectors. Media Scan handles low quality drives in both the degraded mode and during the rebuild process. For additional data security, other intelligent drive management features include the transparent resetting of non-responsive hard drives, power-failure management, and bad-drive handling during LD expansion.
