Product Description
The HPE 649870-B21, also known as the FlexFabric 554M Mezzanine Adapter, is a high-performance dual-port 10 Gigabit Ethernet (10GbE) network adapter designed specifically for HP ProLiant BladeSystem servers. This mezzanine card plugs directly into the server blade's mezzanine slot, providing efficient and high-speed network connectivity. It features two SFP+ ports, supporting 10GbE optical transceivers (typically 10GBASE-SR for short reach), which are essential for demanding data center applications requiring high bandwidth and low latency. The adapter utilizes a PCI Express 2.0 x8 interface, offering sufficient bandwidth to support the aggregate throughput of both 10GbE ports. This ensures that network traffic can be handled efficiently, minimizing bottlenecks for applications such as high-performance computing, storage networking, and server virtualization. The FlexFabric technology integrated into this adapter often provides advanced features for network convergence and management. Key capabilities of the 649870-B21 include support for Single Root I/O Virtualization (SR-IOV), which allows for direct assignment of network resources to virtual machines, improving performance and reducing CPU overhead in virtualized environments. It is designed to integrate seamlessly with HP's server infrastructure, offering reliability and performance for mission-critical workloads within the ProLiant BladeSystem ecosystem.
