Array configuration guidelines

Remember the following factors when you build an array:

All drives grouped in a logical drive must be of the same type (for example, either all SAS or all SATA
and either all hard drives or all solid state drives).

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

and is unavailable for data storage.

The more physical drives configured in an array, the greater the probability that the array will
experience a drive failure during any given period.

To guard against the data loss that occurs when a drive fails, configure all logical drives in an array with
a suitable fault-tolerance (RAID) method. For more information, see "Drive arrays and fault-tolerance

methods (on page

106

)."

Minimum requirements

For minimum operating system requirements to run any HP SSA format, see the HP website

(

http://www.hp.com/go/ossupport

).

Minimum video requirements to run the HP SSA GUI include a minimum monitor resolution of 1024x768 and

16bpp. The GUI supports the following browsers:

Mozilla Firefox 9.0 or later

Microsoft Internet Explorer 8.0 or later

Google Chrome

For a list of supported controllers, see HP Smart Array RAID Controllers on the HP website

(

).

Native support for 64-bit and 32-bit operating

systems

HP SSA now offers a native 64-bit HP SSA application for supported 64-bit operating systems, eliminating
the need for compatibility libraries. A 32-bit HP SSA application is also available. Users can choose to install

the application that matches the OS installed on the server product.
The 64-bit HP SSA application is not a direct upgrade from 32-bit HP SSA. On 64-bit systems running 32-bit

HP SSA, you must uninstall the 32-bit application, and then install the 64-bit application.
