Overview: The Flash Backed Write Cache (FBWC) uses NAND 6 flash devices to retain cache data and super-capacitors (super-caps) instead of batteries to provide power during a power loss. The FBWC offers significant advantages over the HP Battery-Backed Write-Cache (BBWC) system. Since the FBWC writes the contents of memory to flash devices, there is no longer a 48-hour battery life limitation and the data will be posted to the disk drive on the next power up.
