HP StorageWorks Disk Array 12hThe automatic self-optimization and high availability features (99.95% uptime) of the 12H make it a strong choice for operations requiring leading performance for I/O-intensive application workloads such as online transaction processing (OLTP), JFS, and Web servers. The 12h offers the lowest cost array solution scaleable to 2.6TB per 2-meter rack.

Features:

  • Redundant controllers reduce or eliminate downtime caused by failed controller equipment.
  • Hot-pluggable components allow for repairs with minimum interruption to currently running applications
  • Active/active controllers provide hot fail-over, keeping your data safe and available
  • Support for mirrored cache keeps a complete copy of all cached data on both controllers
  • Dual batteries in each controller allow failure of up to three of the four batteries in a controller pair with no resulting downtime
  • ECC protected memory corrects single-bit memory errors and detects two-bit errors; allowing the system to continue operation without interruption even though a memory component may be performing marginally
  • HP C1 manufacturing standard enables it to work reliably in a variety of operating conditions
  • Failure detection in firmware detects battery failure and sends a notice to the management utility, allowing replacement of a battery before it causes a controller failure or loss of data
  • Background disk scrubbing restores data from remaining disks and rewrites data to repaired sectors, and detects and repairs data errors in the background before interruption of system operation
  • Data protection enables recovery of catastrophic controller failures by logging (real-time) controller updates to the disks
  • Award-winning HP AutoRAID technology cuts administrative time needed for installation, performance tuning, and configuration
  • Online capacity upgrades - allows the addition of storage whenever it's convenient; no need to bring the system down
  • Array management monitoring delivered through ARM (AutoRAID Manager) detects and reports many error conditions, allowing correcting during regular hours and minimizing impact on operations or operating staff
  • Automatic migration of data from RAID 0/1 to RAID 5 storage- substantially reduces administrative overhead
  • Ability to mix and match disk drive capacities and speeds simplifies configuration and upgrades
  • Support for HP-UX and NT allows flexible storage capacity allocation or redeployment
  • Interfaces with HP's OpenView, XP/ServiceGuard, and other HA software
