Overview of array configuration tools Utilities available for configuring an array To configure an array on an HP Smart Array controller, three utilities are available: • HP Array Configuration Utility (ACU)-An advanced utility that enables you to perform many complex configuration tasks • Option ROM Configuration for Arrays (ORCA)-A simple utility used mainly to configure the first logical drive in a new server before the operating system is loaded • HP Online Array Configuration Utility for NetWare (CPQONLIN)-A customized version of ACU for online configuration of servers that use Novell NetWare Before you use a utility, confirm that the utility can support the required task. View a comparison of the utilities (on page 5). Whichever utility you use, 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.

Overview of array configuration tools
Utilities available for configuring an array
To configure an array on an HP Smart Array controller, three utilities are available:
•
HP Array Configuration Utility (ACU)
—An advanced utility that enables you to perform many complex
configuration tasks
•
Option ROM Configuration for Arrays (ORCA)
—A simple utility used mainly to configure the first logical
drive in a new server before the operating system is loaded
•
HP Online Array Configuration Utility for NetWare (CPQONLIN)
—A customized version of ACU for
online configuration of servers that use Novell NetWare
Before you use a utility, confirm that the utility can support the required task. View a comparison of the utilities
(on page
5
).
Whichever utility you use, 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
102
)."
