Part No: 598414-001 - HP 1GB Flash-Based Write Cache (FBWC) CL5 Board

Capacity: 1GB
Type: Flash-Based Write Cache (FBWC)
Purpose: This board provides a write cache for compatible HP RAID controllers, storing data temporarily in the cache before it is written to disk. It ensures that in the event of a power failure, data in the cache is not lost, as it will be safely stored in flash memory.
Compatibility: Typically used with HP Smart Array Controllers in servers to enhance write performance and data integrity.
Function: The flash-based design allows for faster write-back operations compared to traditional battery-backed systems. The data is retained in flash memory until it is safely written to disk after power is restored.
