Battery-backed write cache option
The server supports multiple memory modules and RAID levels:
• 256 MB supports RAID 0, 1, 10
• 512 MB supports RAID 0, 1, 5, and 10
CAUTION: To prevent a server malfunction or damage to the equipment, do not add or remove
the battery pack while an array capacity expansion, RAID level migration, or stripe size migration
is in progress.
IMPORTANT: The battery pack might have a low charge when installed. In this case, a POST
error message is displayed when the server is powered up, indicating that the battery pack is
temporarily disabled. No action is necessary on your part. The internal circuitry automatically
recharges the batteries and enables the battery pack. This process might take up to four hours.
During this time, the cache module functions properly, but without the performance advantage of
the battery pack.
NOTE: The data protection and the time limit also apply if a power outage occurs. When power
is restored to the system, an initialization process writes the preserved data to the hard drives.
