HP INTEGRITY RX3600 - Manual (Page 313)

NOTE: To copy a particular array configuration to several other servers on the same network,
use the Array Configuration Replicator (ACR) or the scripting capability of ACU. ACR is provided
in the SmartStart Scripting Toolkit, available on the HP Web site at:
http://www.hp.com/servers/sstoolkit .
Whichever utility you use, the following limitations apply:
•
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.
• The probability that an array will experience a drive failure increases with the number of
physical drives in the array. If you configure a logical drive with RAID 5, keep the probability
of failure low by using no more than 14 physical drives in the array.
For conceptual information about arrays, logical drives, and fault-tolerance methods, and for
information about default array configuration settings, see the HP Array Configuration Utility
User Guide at I/O Cards and Networking Software at:
