Installing the HP Smart Array SAS License Key
When installed and activated on the B320i controller, the HP Smart Array SAS License Key provides support
for SAS hard drives.
To enter the license key, use ACU ("
" on page
After the license key is added, a Validating License Key screen appears, and you will receive confirmation
that the license key has been successfully activated. SAS drives are now enabled. Use ACU to configure the
drives.
Configuring an array
For the most efficient use of drive space, all drives within an array should have approximately the same
capacity. Each configuration utility treats every physical drive in an array as if it has the same capacity as the
smallest drive in the array. Any excess capacity of a particular drive cannot be used in the array. Therefore,
the capacity is unavailable for data storage.
The more physical drives that are in an array, the greater the probability that the array will experience a drive
failure during any given period. To reduce the risk of data loss that might occur when a drive fails, configure
all logical drives in an array with a suitable fault-tolerance (RAID) method.
To configure an array, use Intelligent Provisioning (on page
) to enter the Array Configuration Utility (on
). For more information about using ACU to configure an array, see the Configuring Arrays on HP
Smart Array Controllers Reference Guide on the HP website
Setting the controller read cache
HP Dynamic Smart Array RAID controllers can use a configurable amount of main system memory for read
caching. The default amount of memory used is 64 MB. However, this value can be set to 0, 64, or 128 MB.
Use ACU ("
" on page
) in offline mode to configure the amount of read cache.
