Controller card HP Enterprise P440 12G SAS 4GB FBWC PCIe

HP Enterprise P440 12G SAS controller card with 4GB FBWC and PCIe interface is a server storage controller designed for enterprise environments. It supports 12Gb/s SAS connectivity and integrates a 4GB battery-free write cache (FBWC) to accelerate I/O operations while providing improved protection for cached data. The card fits PCIe host slots and is intended for managing RAID configurations and high-throughput workloads on servers and in data centers.

Advantages

The HP Enterprise P440 offers 12Gb/s SAS throughput and a 4GB FBWC to reduce write latency and increase sustained performance under heavy I/O. Its PCIe interface provides standard connectivity to server motherboards, and the design is focused on enterprise reliability for RAID management and large-scale storage tasks. The battery-free write cache reduces maintenance requirements associated with replaceable batteries.

Suitable for

• RAID configurations in enterprise servers
• High-throughput database and virtualization workloads
• Data center storage consolidation and expansion
• Applications requiring reliable cached write performance
