HPE NC551mProduct Dual Port FlexFabric 10Gb Converged Network Adapter

SKU CH-N69B-GGAEW MPN NC551mProduct

Dual-port mezzanine adapter provides 10Gb converged networking with Flex-10 virtualization and FCoE support for BladeSystem servers

  • Dual 10Gb ports consolidate network and storage traffic
  • Flex-10 divides each port into four physical NICs
  • FCoE support separates Ethernet and Fibre Channel traffic
  • iSCSI offload reduces CPU load for storage workloads
  • Designed for HP BladeSystem server integration

Dual-Port 10Gb Mezzanine Adapter

The HPE NC551m FlexFabric adapter provides two 10Gb converged network ports in a mezzanine form factor for HP BladeSystem servers. It is designed for administrators consolidating Ethernet and storage traffic onto a single physical connection. The card supports Virtual Connect Flex-10 technology for flexible bandwidth allocation across virtualized workloads.

Virtual Connect Flex-10 and FCoE Support

Flex-10 divides each 10Gb port into four physical NICs, allowing granular bandwidth management for virtual machines. When paired with a Convergence Enhanced Ethernet switch, the adapter separates Fibre Channel over Ethernet and standard Ethernet traffic onto the appropriate networks. Full iSCSI protocol offload reduces CPU overhead compared to software initiators, freeing compute cycles for applications.

BladeSystem Mezzanine Installation

The mezzanine form factor installs directly into a compatible BladeSystem server bay without cables or external brackets. Compatibility is limited to HPE BladeSystem enclosures that accept FlexFabric mezzanine cards; it will not fit standard PCIe slots or non-HPE blade chassis. Verify the server model supports this specific mezzanine type before purchase.

Questions about this item

What maintenance or replacement will the NC551m mezzanine adapter need later?

The NC551m is a passive converged network adapter with no moving parts or user-serviceable components, so it requires no scheduled maintenance or replacement during its service life.

What limit appears first on the NC551m under sustained 10 Gb load?

Each of the two 10 Gb ports can be divided into four physical functions via Virtual Connect Flex-10, so the port-level bandwidth ceiling is reached before any internal adapter bottleneck.

How much noise and heat does the NC551m generate inside a blade running all day?

The adapter has no fan and draws power only for its two 10 Gb ports, adding minimal heat and zero acoustic noise to the blade enclosure.
