Product information

Description

RAID controller battery module HP Enterprise P440 4GB FBWC 12G SAS 1P PCIe (MPN 749797-001-RFB) is a battery-backed write cache (FBWC) replacement module designed for compatibility with HP Enterprise P440 RAID controllers supporting 12G SAS and a single PCIe port. The module provides 4GB of non-volatile cache to preserve in-flight write data during power interruptions, helping to prevent data loss and corruption and to enable safe recovery after outages. It is intended as a field-replaceable unit for servers that use the specified RAID controller family and require reliable write caching behavior.

Advantages

The HP Enterprise P440 4GB FBWC module maintains cached write data in the event of unexpected power loss, reducing the risk of file system corruption and incomplete transactions. With 4GB of cache capacity it supports sustained write performance improvements for workloads that rely on write caching. The module is designed to fit the form factor and electrical interface of the P440 controller, ensuring compatibility and straightforward installation when used with matching controller firmware and hardware.

Suitable for

  • Enterprise servers using HP Enterprise P440 RAID controllers with 12G SAS interfaces
  • Systems requiring reliable write-back caching to protect write transactions during power loss
  • Database, virtualization, and transactional workloads that benefit from improved write performance
  • Field replacement or upgrade of existing battery-backed cache modules in compatible servers

Key specifications

  • Manufacturer: HP Enterprise
  • Model / MPN: 749797-001-RFB
  • EAN: 5706998859990
  • Cache type: FBWC (Battery-backed write cache)
  • Cache capacity: 4GB
  • Interface compatibility: 12G SAS, 1-port PCIe RAID controller (P440 family)

How to use

Install the battery module according to the server and RAID controller maintenance instructions. Power down the server and follow the manufacturer’s replacement procedure for the P440 controller to seat the module securely in the appropriate socket. After installation, power up the system and verify that the controller firmware recognizes the FBWC module and that the cache status reports as healthy in the RAID management utility. Ensure controller firmware and management software are up to date before returning the system to production.

Usage recommendations

Use this FBWC module only with supported HP Enterprise P440 RAID controllers and compatible server platforms. Regularly monitor battery health and RAID controller logs, and follow HP Enterprise guidelines for battery replacement intervals and firmware updates to maintain data integrity and optimal cache performance.
