HPE FlexFabric 10GbE 2-port 554M Adapter (G8) | 647590-B21

The HPE FlexFabric 10GbE 2‑port 554M Adapter (part number 647590‑B21) is a mezzanine-style converged network adapter tailored for HPE BladeSystem c-Class Gen8 servers, such as the ProLiant BL420c, BL460c, BL465c, and BL660c G8 ebay.com+9harddrivesdirect.com+9usapartsdirect.com+9. It features two internal 10 GbE ports and is built around the Emulex BE3 chipset, offering full offload support for Ethernet, Fibre Channel over Ethernet (FCoE), and iSCSI, thanks to its hardware acceleration capabilities like TCP Offload Engine (TOE) for stateless TCP/IP and full FCoE handling storagepartsdirect.com+3harddrivesdirect.com+3usapartsdirect.com+3. The adapter supports Virtual Connect Flex‑10, enabling each 10 GbE port to be partitioned into four virtual NICs, optimizing bandwidth allocation for heavily virtualized environments 

In addition to its robust virtualized networking capabilities, the 554M adapter aids data center efficiency by combining network and storage traffic paths onto a single module, reducing cabling complexity and lowering both capital and operational costs ebay.com+7renewtech.com+7harddrivesdirect.com+7. With onboard 128 MB flash memory for firmware, PCIe 2.0 x8 connectivity, jumbo-frame support, and comprehensive multiprotocol offloading (including iSCSI and FCoE), it delivers high performance while preserving CPU resources renewtech.com+4harddrivesdirect.com+4storagepartsdirect.com+4. Overall, the 647590‑B21 is an essential component for organizations deploying Gen8 blade infrastructure that require scalable, converged fabric solutions.
