## Long description

The HP 1GB FBWC Module 633542-001-RFB is a 1GB battery-backed cache memory module using DDR2 technology and operating at 533MHz. Designed for use with compatible HP Enterprise server controllers, this FBWC (Flash-Backed Write Cache) module stores write cache data to improve write performance and protect cached information in case of power loss. The module is intended as a component upgrade to enhance storage controller caching capacity and help maintain data integrity during unexpected outages.
Advantages
The FBWC module increases available cache capacity, allowing more write operations to be staged in fast memory before being committed to storage. Its DDR2 architecture at 533MHz provides predictable latency and throughput characteristics for server caching tasks. Battery-backed and flash-backed mechanisms work together to preserve cached data during power interruptions, reducing the risk of data loss. The compact form and compatibility with HP Enterprise controllers make it straightforward to integrate into supported systems.
Suitable for
 Upgrading server controller cache capacity to improve write performance
 Environments with mixed read/write workloads where write caching can reduce storage latency
 Systems requiring protection of in-flight write data against power failures
 Datacenters and enterprise servers that use HP-compatible RAID or storage controllers
Key specifications
 Capacity: 1 GB of cache memory
 Memory type: DDR2
 Operating frequency: 533 MHz
 Function: Battery/flash-backed write cache for storage controllers
 Primary use: Improves write performance and preserves cached data on power loss
How to use
Install the FBWC module according to the server or controller manufacturer's service manual: power down the system if required, insert the module into the designated cache module slot on the storage controller, and secure it following the hardware instructions. After physical installation, verify firmware and controller settings to ensure the controller recognizes the additional cache and that any controller-level caching policies are configured according to operational needs. Perform a controlled reboot if guided by the vendor documentation and confirm normal operation in the server management interface.
Usage recommendations
Use this DDR2 533MHz 1GB FBWC module in systems and controllers listed as compatible by HP Enterprise. Before installation, review controller firmware versions and update if necessary to ensure full functionality. Monitor cache health and battery/flash status through server management tools and follow standard data center procedures for backups and maintenance to complement the module's data protection features.
