IBM - 22R6833 - BladeCenter SAS RAID Controller Battery

The IBM 22R6833 BladeCenter SAS RAID Controller Battery is a dedicated cache backup battery designed to protect RAID controller cache contents during unexpected power events. Used with BladeCenter SAS RAID controller configurations, it helps preserve unwritten data so arrays can recover cleanly after power is restored—an important reliability component in virtualisation hosts, database nodes, and shared storage workloads.

This spare part is commonly deployed in IBM BladeCenter environments where SAS RAID controllers and battery-backed cache are used to support consistent write performance and data integrity. When planning maintenance or upgrades, it can also be useful to align your spares strategy across related IBM infrastructure components, including performance tiers built on SSD and capacity tiers using HDD, as well as connectivity options such as HBA.
