HP 694033-B21 512MB Flash Back Write Cache FIO Kit

Product Description

The HP 694033-B21 is a 512MB Flash Back Write Cache (FBWC) kit, an essential component for optimizing the performance of HP ProLiant servers equipped with compatible Smart Array RAID controllers. This module serves as a high-speed buffer for write operations, significantly improving the input/output (I/O) performance of disk arrays. By temporarily storing write data, it allows the host system to proceed with other tasks without waiting for the slower storage devices to complete the write operation. A key feature of the FBWC is its data protection capability. It is typically powered by a battery module (often included or sold separately, depending on the specific kit configuration) that ensures the cached data is preserved in the event of a sudden power loss or server reboot. Upon restoration of power, the controller can then safely write the cached data to the disks, preventing data corruption or loss. This 512MB FBWC kit is designed to be installed directly onto compatible HP Smart Array controllers. It is a crucial upgrade for environments requiring high write performance, such as database servers, transaction processing systems, and applications that generate a large volume of write data. The 694033-B21 is a genuine HP part, ensuring seamless integration and reliable operation with supported HP server hardware.
