HP 512MB Flash Backed Cache Kit, 512MB, DDR2, 400MHz

The HP 512MB Flash Backed Cache Kit is a 512MB DDR2 memory module running at 400MHz designed to improve caching performance in compatible HP servers and storage controllers. The module combines volatile DRAM capacity with a flash-backed mechanism that preserves cached write data during power loss, helping maintain data integrity and reduce rebuild times. Its compact form factor and standard DDR2 400MHz timing allow straightforward installation into supported systems used in data center environments.

Advantages

This Flash Backed Cache Kit increases write caching efficiency by providing low-latency DDR2 memory paired with non-volatile protection. By preserving cached data during unexpected power interruptions, it reduces the risk of data loss and supports faster recovery. The module's 400MHz DDR2 performance balances throughput and latency for mixed I/O workloads, while its compatibility with HP server storage controllers simplifies integration and replacement.

Suitable for

• Improving write cache performance in HP server RAID and storage controllers
• Data centers requiring protected cache to reduce rebuild and recovery times
• Systems running mixed transactional and sequential workloads
• Environments where reliable short-term data persistence is needed during power loss

Key specifications

• Memory capacity: 512MB
• Memory type: DDR2
• Operating frequency: 400MHz
• Function: Flash-backed cache (volatile DRAM with non-volatile protection)
• Form factor: module designed for server/cache controller installation

How to use

Install the module into the designated cache slot of a compatible HP server or storage controller following the server manufacturer's service manual. Ensure the system is powered down and appropriate electrostatic discharge precautions are taken before handling the module. After physical installation, verify that the server firmware and storage controller recognize the module and configure cache settings in the controller management interface according to workload requirements.

Usage recommendations

Use this kit in systems listed as supported by the server or storage controller documentation. Keep firmware and controller drivers up to date to ensure correct operation of flash-backed protection. Monitor cache health and capacity through management tools and replace the module with an equivalent specification if performance degradation or errors are reported.
