HPE727060-B21

FlexFabric 10 Gb 2-Port 556FLR-SFP+Network Adapter

The HPE727060-B21 FlexFabric 556FLR-SFP+ adapter is a dual-port, 10 Gigabit Ethernet FlexibleLOM module designed for HPEProLiant Gen9 servers.It delivers converged networking with RDMA over Converged Ethernet (RoCE) and Tunnel Offload (VXLAN/NVGRE), enabling optimized performance for virtualization, storage, and overlay networking in cloud and enterprise environments. With two SFP+ports, this card provides up to 40 Gb/s bi-directional bandwidth and accelerates services such as live migration and SMB Direct with minimal CPU impact.

Features

Designed for the FlexibleLOM socket in Gen9 rack or tower servers, the adapter connects via PCIe 3.0 ×8 for full throughput. Built on an Emulex XE-102 (Broadcom) controller, it delivers enterprise-grade network convergence including iSCSI, FCoE, RoCE, and tunnel offload. Capable of supporting costs- and performance-critical workloads like SMB Direct, Hyper-V live migration, and VXLAN overlays, it boosts efficiency while reducing latency. With 128 MB onboard memory and full support for jumbo frames, Wake-on-LAN, PXE boot, VLAN, LACP, RSS, MSI-X, and TCP/UDP offloads, it's a versatile choice for modern data centers.

Advanced Options

Engineered for high-efficiency virtualization and overlay networking, this adapter delivers consistent 10 Gb throughput per port with very low latency. RDMA and tunnel offload reduce CPU cycles during network-intensive tasks such as VM migration or SMB storage.
