Frequently Asked Questions
What does a flash-backed write cache (FBWC) do?
The FBWC module stores pending write data in flash memory rather than relying solely on a battery-backed DRAM cache. If the server loses power unexpectedly, the data is preserved in non-volatile flash until power is restored and the writes can be committed to disk.
Which RAID controllers is the HP 587324-001 FBWC compatible with?
This module is designed for use with HP Smart Array controllers that support flash-backed write cache. Check HP's compatibility matrix for your specific controller model (e.g., P410, P411, P212, P812) to confirm support.
How does FBWC differ from a traditional battery-backed write cache (BBWC)?
Unlike BBWC, which relies on a rechargeable battery to maintain cached data during a power loss, FBWC transfers cached data to flash memory, which retains it indefinitely without battery power. This eliminates battery replacement cycles and provides more reliable data protection.
