Storage HBA HP St.Works 81Q AH400A-RFB — PCIe, 8GB

HBA HP St.Works 81Q AH400A-RFB — PCIe, 8GB is a host bus adapter for storage connectivity that provides an 8Gb/s Fibre Channel interface over a PCIe card. Designed to connect storage arrays, SANs or external Fibre Channel storage to servers and workstations, this HP-branded HBA enables high-throughput data transfer for backup, virtualization and I/O-intensive applications. The card fits standard PCIe slots and carries the manufacturer part number AH400A-RFB and EAN 5711783592884 for identification.

Advantages

The adapter delivers a dedicated 8Gb/s Fibre Channel link to offload storage traffic from server CPUs and to improve throughput and latency for storage operations. As a PCIe host bus adapter, it supports integration into existing server systems without requiring major infrastructure changes. The HP St.Works model is suitable for deployments where predictable storage performance and compatibility with Fibre Channel SANs are required. The card’s single-function design focuses on reliable connectivity and standardized protocol support.

Suitable for

• Connecting Fibre Channel storage arrays and SANs to servers and workstations
• Backup and restore operations requiring sustained throughput
• Virtualization hosts that need dedicated storage bandwidth
• I/O-intensive applications such as databases and file servers
• Upgrading or expanding storage connectivity in compatible systems

How to use

Install the HBA into an available PCIe slot on a compatible server or workstation following the system manufacturer’s service manual. Secure the card in the chassis, connect the appropriate Fibre Channel cable to the adapter and to the SAN or storage array, and power on the system. Install or update vendor-recommended drivers and firmware so the operating system recognizes the adapter. Configure zoning and LUN access on the SAN side as required, then verify link status and throughput through the host’s storage management tools.

Usage recommendations

Use certified Fibre Channel cables and maintain firmware and driver versions recommended by HP to ensure compatibility and stable performance. Verify server BIOS and PCIe slot capability (lane count and generation) to match expected throughput, and follow data centre best practices for cabling, grounding and SAN zoning when integrating the AH400A-RFB HBA.
