IBM 81Y4451 RAID Battery

The IBM 81Y4451 is a lithium-ion battery module designed for the ServerRAID M5000 controller. It provides backup power to preserve write-cache data during unexpected power loss. This component is intended for server administrators maintaining existing M5000 deployments.

Capacity and headroom

The battery sustains cache memory long enough for safe write-back operations during brief outages. It does not extend runtime for the server itself or support extended uptime. Capacity diminishes with age and charge cycles, eventually requiring replacement to maintain data integrity. Buyers needing longer backup duration or support for different controller models should look elsewhere.
