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 116)."
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
16-bit color. The GUI supports the following browsers:

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.
Future versions of HP SSA will be available as native 32-bit or native 64-bit applications, as long as 32-bit
operating systems are supported.
