2GB cache

HP 2GB Flash Cache module 633543-001-RFB is a flash-backed write cache module for supported HPE Smart Array controllers. It provides a cache layer for storage operations in server configurations that use a compatible controller.

HPE identifies the corresponding base part, 633543-001, as a 72-bit FBWC memory module for the P420, P421, P430, P431, 822 and 830 Smart Array controllers. The cache module is supplied separately from the controller board and capacitor module; those parts are not included with it.
