Our take on the Dell 0KVY4F EQL PS6100 Controller Cache Battery

The Dell 0KVY4F is the cache battery module for the EqualLogic PS6100 controller. It keeps the controller's write cache alive during a power loss so cached data can be flushed to disk. It is a replacement part, not an upgrade: you buy it when a PS6100 controller reports a failed or aging cache battery. Third-party equivalents exist, but this is the Dell part number, which matters for warranty and firmware compatibility on an EqualLogic array.

Questions and answers

What does this battery do in a PS6100?
It backs up the controller's write cache during a power loss so cached writes are not lost. A failed battery can push the controller into write-through mode and slow the array.
Is it compatible with other EqualLogic models?
It is the cache battery for the PS6100 controller. Do not assume it fits PS4100, PS6210 or other arrays; check the part number for your model.
Do I need to shut down the array to replace it?
On a dual-controller PS6100 the battery is serviced per controller, so the array can usually stay online. Follow Dell's service procedure for your firmware.
Is a third-party battery a safe substitute?
It can work, but a non-Dell battery may affect support and warranty on the array. For a production system, the Dell part number is the safer match.
How long does the battery last?
Cache batteries are consumables and degrade over years of service. Replace it when the controller reports a failure or the array warns about the battery.
