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.
