HPE 8Gb Fibre Channel Mezzanine Adapter

The HPE 651281-B21 QMH2572 is an 8Gb Fibre Channel Host Bus Adapter designed for BladeSystem c-Class enclosures. It provides two 8Gb/s Fibre Channel ports over a PCI Express interface. This mezzanine card suits server administrators adding SAN connectivity to compatible blades.

Administrators expanding c-Class SAN connectivity

This adapter fits administrators deploying or maintaining HPE BladeSystem c-Class environments that require dual-port 8Gb Fibre Channel connectivity. It supports Microsoft Windows Server 2008 R1 SP2 x64, VMware 4.1 and 5.0, Red Hat Enterprise Linux 5.7 and 6.0, SLES 10 and 11, and Solaris 10. Builders using non-c-Class servers, different mezzanine form factors, or operating systems outside the supported list should select a different adapter.

Two 8Gb/s Fibre Channel ports on PCI Express Gen I

The card delivers two 8Gb/s Fibre Channel ports on a PCI Express bus that operates at Gen I x8 or Gen II x4. This port count and bus configuration determines whether the adapter matches the blade slot and fabric speed required for the deployment.
