HPE 867959-B21 Smart Storage Battery – Backup Power Module for Smart Array Controllers, Gen9/Gen10

The HPE 867959-B21 Smart Storage Battery is a critical backup power module designed to support HPE Smart Array RAID controllers in ProLiant Gen9 and Gen10 servers. It provides reliable power to the controller cache, ensuring that cached data is preserved and safely written to storage in the event of a power failure.

This battery module works in conjunction with Flash-Backed Write Cache (FBWC) systems, enabling enterprise-level data protection and preventing data loss during unexpected outages. It ensures that write cache data is retained long enough to be securely flushed to non-volatile storage, maintaining system integrity and reliability.
