HPE 651281-B21 – QMH2572 8Gb Fibre Channel HBA

Overview

The HPE 651281-B21 is a dual-port 8Gb Fibre Channel Host Bus Adapter designed for HPE BladeSystem c-Class server environments. It provides Fibre Channel SAN connectivity between blade servers and enterprise storage infrastructure for high-speed data transfer operations.

It is used in enterprise data centers where low-latency storage communication and reliable SAN connectivity are required for virtualization, database, and storage-intensive workloads. The adapter supports Fibre Channel networking with backward compatibility for older FC environments.

The module is implemented as a PCI Express mezzanine card for compatible HPE Gen8 blade servers. Its mezzanine design allows storage networking integration without consuming standard expansion slots within the blade architecture.

It is commonly deployed in BladeSystem infrastructures connected to Fibre Channel SAN fabrics requiring scalable and redundant storage access.

Typical Deployment Scenarios

Used in HPE BladeSystem c-Class Gen8 server blades connected to enterprise SAN environments. Common in virtualization clusters, database platforms, backup infrastructures, and storage-intensive enterprise applications requiring Fibre Channel connectivity. Also deployed in high-density blade server environments with centralized storage architectures.
