Memory Module Hewlett Packard Enterprise FBWC 512MB Gen8 1600MHz

The Hewlett Packard Enterprise Smart Array 512MB FBWC Gen8 is a battery-backed memory module intended for enterprise server controllers. With 512MB capacity and 1600MHz operation, this FBWC (flash-backed write cache) module stores cached write data and maintains integrity during power loss, supporting consistent write performance for Smart Array controllers in Gen8 server platforms. It is designed to integrate with compatible HPE controller cards to help reduce write latency and protect data in the event of unexpected shutdowns.

Advantages

This memory module provides non-volatile protection for cached writes, improving data reliability without user intervention. The 1600MHz operating rate supports timely cache transfers while the 512MB capacity balances storage for typical transactional workloads. The FBWC design uses flash backup to preserve cache contents when power is removed, eliminating the need for frequent battery replacements and simplifying maintenance.

Suitable for

• Enterprise server environments using HPE Smart Array controllers
• Database and transactional workloads requiring write-cache protection
• Systems where maintaining cache integrity during power interruptions is important
• Server maintenance setups aiming to reduce maintenance overhead related to battery-backed caches

Key specifications

• Capacity: 512 MB of cache-backed memory
• Operating frequency: 1600 MHz
• Function: Flash-backed write cache for controller-level write protection
• Compatibility: Designed for Gen8 server controller architectures (HPE Smart Array)
• Data protection mechanism: Flash backup to retain cache contents during power loss

How to use

Install the FBWC module into the compatible Smart Array controller slot following the server and controller manufacturer's installation procedures. After physical installation, verify that the controller firmware recognises the module and that cache protection is enabled in controller settings or management utilities. Monitor cache health and status through the server management interface and ensure firmware is up to date to maintain compatibility and reliable operation.

Usage recommendations

Use the module with supported HPE Smart Array controllers in Gen8 platforms and keep controller firmware current. Verify that the server environment meets the controller’s power and thermal requirements. For critical systems, perform periodic checks of controller logs and management alerts to confirm the FBWC is operating correctly and storing cache data as expected.
