Controllers
Find your storage array controller by brand first: Dell Compellent, Dell EqualLogic, Dell PowerVault and HPE Nimble controllers each have their own page, and controllers for other arrays, such as HPE 3PAR StoreServ nodes, belong to this parent category. Check the array model, the host connection and the cache of the controller you are replacing before you order. Every controller is tested before it ships; where no price is shown, request a quote from the product page.

Replacing an array controller
Dual-controller arrays let you replace one controller while the other keeps the storage online, but each family sets its own conditions:
| Array family | With one controller out | Matching rule |
|---|---|---|
| Dell PowerVault ME4 and ME5 | Controller modules are hot-swappable in a dual-controller enclosure, and the partner runs the system | Both controllers of the same model type; swap within 5 minutes (2U) or 7 minutes (5U) |
| Dell EqualLogic PS Series | The array runs on one control module, and a module can be installed without shutting down | Same type and color as the other module, on the same firmware; carry the failed module's microSD card over to the new one |
| Dell Compellent SC Series | The other storage controller keeps operating; fit the service baffle within three minutes of pulling the failed one | Move the I/O card, mezzanine card and battery backup unit to the replacement, which updates to the surviving controller's software |
| HPE Nimble Storage | If one controller fails the other takes over, and the array runs on the healthy one during the swap | A controller ordered from HPE; move the PCIe cage from the failed controller |
Firmware is part of the match. Dell's EqualLogic manual warns that if the two control modules run different firmware, only one will be functional, while Compellent SC5020 systems and PowerVault ME arrays bring a new controller to the surviving controller's version. Controllers by brand are on PowerVault, EqualLogic, Compellent and HPE Nimble.
