Introduction
HP provides four utilities for manually configuring an array on a Smart Array controller:
•
ORCA—A simple ROM-based configuration utility
•
ACU—A versatile, browser-based utility that provides maximum control over configuration
parameters
•
ACU CLI—A command line version of ACU
•
CPQONLIN—A menu-based configuration utility specifically for servers using Novell NetWare
For more information about the features of these utilities, see "Comparing the Utilities (on page
Whichever utility you use, be aware of the following limitations:
•
For the most efficient use of drive space, do not mix drives of different capacities within the same
array. The configuration utility treats all physical drives in an array as if they have the same capacity
as the smallest drive in the array. The excess capacity of any larger drives is wasted because it is
unavailable for data storage.
•
All drives in an array must be of the same type (for example, all SAS or all SATA).
•
The probability that an array will experience a drive failure increases with the number of physical
drives in the array.
For conceptual information about arrays, logical drives, and fault-tolerance methods, and for information
about default array configuration settings, refer to the HP Array Configuration Utility User Guide. This
document is available on the Documentation CD that is provided in the controller kit.
