About HP SmartCache

HP SmartCache enables solid state drives to be used as caching devices for hard drive media. Data can be

accessed from the solid state drive instead of hard drives. HP SmartCache provides the following features:

• Accelerates application performance

• Provides lower latency for transactions in applications

• Supports all operating systems, without the need for changes

HP SmartCache will be fully enabled after the first SmartCache is created on the controller.

The following features cannot be performed unless HP SmartCache is disabled:

• Expand Array

• Advanced Capacity Expansion

• Move Logical Drive

• Replace Array

• Mirror Splitting and Recombining (offline only)

• Split Mirror Backup and Rollback (online and offline)

• Heal Array

• Extend Logical Drive

• Migrate RAID/Strip Size

• Change Cache Ratio

• Align Logical Drives

To support HP SmartCache, the Smart Array Controller firmware must meet the following version minimums.

• 6G controller: version 3.42 or later

• 12G controller: original release or later.

HP SmartCache requires an HP SmartCache license. For more information, see the HP website

(http://www.hp.com/go/smartcache).

Enabling HP SmartCache with an array will accelerate data input/output for the assigned logical drives. At

least one logical drive must be created on the controller prior to enabling HP SmartCache.
