Cache module HP Enterprise 587324-001 flash-backed write cache with supercapacitor, 610 mm

The HP Enterprise flash-backed write cache module with supercapacitor, 610 mm, provides short-term power protection for server and storage controller caches. It preserves volatile write cache contents during unexpected power loss by supplying enough energy to transfer cached data to non-volatile storage. The module is intended for use in compatible HP Enterprise systems where maintaining data integrity for in-flight write operations is required.

Advantages

This cache module combines a flash-backed design with a supercapacitor to deliver immediate, reliable short-term power for cache preservation without the maintenance requirements of batteries. The 610 mm form factor fits designated expansion slots in supported server and storage platforms. By protecting write cache contents during outages, the module helps reduce the risk of data corruption and supports predictable recovery procedures after power events.

Suitable for

• Server and storage controllers requiring write cache protection
• Environments where short-term power loss could affect write operations
• Data centers and enterprise installations with transactional workloads
• Systems where battery-free power protection is preferred

Key specifications

• Protection type: flash-backed write cache with supercapacitor
• Form factor length: 610 mm
• Function: preserves volatile cache contents during power loss to allow safe commit to non-volatile storage
• Compatibility: designed for supported HP Enterprise server and storage controller slots (verify platform support before installation)

How to use

Install the module into the designated cache module slot of a compatible HP Enterprise server or storage controller according to the platform installation guide. After physical installation, verify that the host system recognizes the module and that firmware and controller settings are configured to use flash-backed write cache. Monitor the system management utilities for status indicators related to cache health and supercapacitor condition to ensure ongoing protection.

Usage recommendations

Confirm platform compatibility and the required firmware level before installation. Place the module in the correct slot and follow the vendor's safety procedures for handling electronic components. Periodically check system logs and management tools to verify the cache module is functioning and that cached data protection is active.
