Our take on the Dell KVY4F EQL PS6100 Controller Cache Battery

The Dell KVY4F is the cache battery module for the EqualLogic PS6100 controller. It keeps the controller's write cache backed up so data survives a power loss, and it is a service part rather than an upgrade: it restores a PS6100 array to its designed behavior. Buyers are storage administrators maintaining aging EqualLogic hardware, not general shoppers. Compared with third-party replacements, the Dell part carries the correct fit and firmware expectations for the PS6100 controller.

Questions and answers

What does this battery do in a PS6100?
It backs up the controller's write cache so cached data is not lost if power fails. A failed battery can push the array into a write-through mode that slows writes.
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 model and controller revision first.
Is this a new or refurbished part?
That depends on the seller. Confirm the condition and any warranty before ordering, since battery age affects how long the replacement will last.
Do I need to power down the array to replace it?
Follow Dell's service procedure for the PS6100. The battery sits on the controller, and the correct steps depend on whether you replace it with the array running or shut down.
Will a new battery fix slow write performance?
If the slowdown comes from a failed cache battery forcing write-through mode, replacing it can restore normal cached writes. Check the array logs first to confirm the battery is the cause.
