Battery-backed write cache option

NOTE: This feature applies only to SCSI models.

Along with the cache module, the battery pack provides transportable data protection, increases overall

controller performance, and maintains any cached data for up to 72 hours. The NiMH batteries in the

battery pack are continuously recharged through a trickle-charging process whenever the system power is

on.

For information on BBWC LEDs, refer to "Battery-backed write cache LEDs (on page 25)" and "Battery-

backed write cache LED statuses (on page 25)."

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.
