HPE 700076-B21

FlexFabric 630M 20 Gb 2‑Port Network Adapter

The HPE 700076‑B21 FlexFabric 630M Adapter is a high-density dual-port 20 Gigabit Ethernet mezzanine network  card engineered for HPE BladeSystem c-Class Gen8 and Gen9 servers. With advanced virtualization and converged networking capabilities, this adapter supports Flex‑20 technology to divide each 20 Gb port into four virtual NICs. Ideal for blade servers running virtualized workloads, it delivers exceptional throughput, intelligent network partitioning, and streamlined I/O convergence across LAN/SAN environments.

Features

This FlexFabric adapter features the QLogic BCM57840S chipset and offers full-duplex 20 GbE connectivity complemented by Fibre Channel over Ethernet (FCoE) support. Designed to slot into Type A or B mezzanine bays on HPE blade servers, it integrates with Virtual Connect FlexFabric architecture to simplify bandwidth provisioning. Bandwidth per virtual NIC can be finely adjusted—from 100 Mb/s up to 20 Gb/s—to match workload requirements while ensuring optimal resource utilization It also supports major networking and virtualization offloads—such as TCP/IP offload, TSO/LSO, MSI‑X, RSS, jumbo frames, NVGRE/VXLAN tunnel offload, SR‑IOV, NPAR, and PXE boot—enhancing performance and reducing host CPU overhead

Advanced Options

Designed for data center efficiency, the 630M adapter delivers up to 80 Gb/s aggregated bidirectional bandwidth when combined with Virtual Connect F8 modules. Hardware acceleration for packet processing significantly reduces server CPU load while ensuring low-latency throughput, essential for virtual machine density and storage traffic performance
