HP StorageWorks Disk Array 12h

The 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
