Click

Enable HP SmartCache

Select a solid state drive type.

Select one or more physical drives from the list of available drives.

Click

Save

Some features may not be available with HP SmartCache enabled.

With the SmartCache selected in the left panel, click

Create SmartCache for Logical Drive

Select the logical drive to cache.

Select the size of the cache. HP recommends 10% of the drive size, and it must be a minimum of 1 GiB.

10.

Click

The SmartCache is created for the Logical Drive.

Working with mirrored arrays

Among the advanced tasks possible with the ACU GUI, you can split a mirrored array and then recombine

it. This process entails breaking a RAID 1 or RAID 1+0 mirror into two identical new arrays consisting of RAID
0 logical drives.
Support for these procedures requires the following:

•

The ACU GUI must be run in offline mode.

•

Select controller models must have a valid SAAP license ("

About SAAP

" on page

•

Mirrored arrays being split can have RAID 1, RAID 1+0, RAID 1 (ADM), or RAID 10 (ADM)

configurations. Arrays with other RAID configurations cannot be split.

Several reasons exist for splitting and recombining a mirrored array. For more information, see the "

RAID

1(+0): breaking mirrors and rebuilding drives
