HPE700761-001

FlexFabric 20 Gb 2-Port 650FLB Network Adapter(FlexibleLOM)

The HPE700761-001 adapter (also known as the 650FLB) is a 20 Gbps dual-port FlexibleLOM Network Adapter designed for HPEProLiant servers. This high-throughput card delivers converged networking and storage connectivity via HPEFlexFabric technology×supporting both Ethernet and RoCE or FCoE traffic over the same ports. Installed in the Flexible LOM slot of supported HPEblade and rack servers, it provides significant bandwidth increase while consolidating cabling and simplifying deployment. Ideal for virtualization, hyperconverged infrastructure, or converged fabric use cases, the adapter supports advanced offloads like tunnel acceleration (VXLAN/NVGRE), SR-IOV, and RDMA for improved efficiency.

Features

Built on Emulex-based silicon and compliant with PCIe 3.0 x8 FlexibleLOM form factor, the 650FLB is engineered to support high-speed fabrics while freeing up mezzanine slots for additional I/O. Each port supports 20 Gigabit Ethernet lanes, and the adapter supports converged Fabric technology, allowing ROCE or FCoE over Ethernet. It offloads overlay network protocols×such as VXLAN and NVGRE×for optimized virtualization workflows and simplified tenant isolation. Tunnel offloading combined with RDMA support drastically reduces CPU usage and latency during VM migration, storage access, or network-intensive operations. Compliance with LACP, jumbo frames, QoS tagging, flow control, and advanced features like MSI-X, LSO/TSO, and Wake-on-LAN ensures enterprise-grade functionality. Designed for compatibility with HPEGen8 through Gen10 servers, this Network Adapter integrates with HPEVirtual Connect, simplifying aggregation and management.

Advanced Options

Optimized for data center environments, this adapter delivers consistent high-bandwidth performance with minimal latency. The convergence of storage and Ethernet traffic over the same link simplifies cabling and reduces switch port count while accelerating network I/O performance. Tunnel-offloading and RDMA support lower processing overhead×ideal for virtualized or storage-centric workloads such as Live VM migration,
