FlexFabric 554M 10 GbE Mezzanine Adapter– 2‑Port FlexibleLOM

The HPE647588‑001, also known as the 554M FlexFabric Adapter, is a server mezzanine network card designed for HPE BladeSystem c-Class Gen8 servers. It delivers two 10 GbE ports using 10GBASE-KX4 over backplane mezzanine slot Type A with support for both Ethernet and Fibre Channel over Ethernet (FCoE), enabling converged I/O in virtualized and storage-intensive environments. This dual‑port card integrates hardware offloads—such as stateless TCP/IP acceleration and TOE—to offload CPU processing, improving performance in enterprise workloads and virtualization clusters. OEM-certified and fully tested, it provides optimized connectivity for blade chassis deployments..

Features

Built on Emulex silicon, the 554M Adapter offers two 10 GbE ports over PCIe 2.0 ×8 mezzanine interface, delivering bandwidth efficient and low-latency connectivity. The card features hardware offload for TCP/IP, Fibre Channel over Ethernet (FCoE), and stateless TOE to reduce CPU load in high-throughput environments. Each unit includes embedded flash memory (~128 MB) for firmware and boot features. Certified for blade servers such as HPE ProLiant BL460c Gen8, BL420c Gen8, and BL660c Gen8, the Adapter seamlessly integrates into server chassis supporting FlexFabric technology.

Advanced Options

In GEN8 blade systems, the FlexFabric 554M provides scalable, converged networking, suitable for unified server/storage fabrics. Mezzanine form factor minimizes chassis footprint while enabling high-speed connectivity. Refurbished units typically include a 90‑day warranty from reseller sources, while OEM-new sealed units are available through official channels. Performance-optimized for both Ethernet and storage overlay environments, this Adapter remains relevant in legacy Gen8 chassis deployments.Optimized for blade server environments, the 554M Adapter provides reliable and predictable networking performance by offloading critical transport processing. The onboard TOE (TCP Offload Engine) and stateless TCP/IP acceleration relieve host CPU resources, enabling more efficient virtualization and storage workloads. FCoE integration enables unified SAN and LAN traffic over a single physical interface.
