HPE 700066-B21 

FlexFabric 630FLB Dual‑Port 20 Gb Gigabit Ethernet Adapter 

The HPE 700066‑B21 FlexFabric 630FLB adapter is a high-throughput 2‑port 20 Gb Ethernet FlexibleLOM card designed for HPE BladeSystem c-Class servers. Fully compatible with Virtual Connect FlexFabric environments, it delivers enterprise-class performance, dividing each 20 GbE port into up to four physical NICs via Network Partitioning (NPAR). With support for VLAN, SR‑IOV, iSCSI/FCoE acceleration, tunnel offloads, and intelligent offload engines, it’s ideal for virtualization, converged networking, and storage-centric workloads. This refurbished model offers cost-effective enhancements to HPE Gen8/Gen9/Gen10 blade deployments with a proven component architecture.

Features

Operating within blade chassis, this FlexibleLOM integrates seamlessly into Virtual Connect Flex‑20 interconnect modules, mapping internal ports to high-speed server fabric for optimized bandwidth utilization . Each port supports 40 Gb/s full-duplex throughput (80 Gb/s aggregate), enabling high-density, low-latency networking for virtual server clusters and storage traffic . Features like SR‑IOV, network partitioning, and tunneling offload (NVGRE/VXLAN) reduce CPU overhead while enhancing VM agility and network segmentation without sacrificing performance

Advanced Options

Engineered for high-availability enterprise blade architectures, this adapter delivers consistent, ultra-low latency performance under virtualization-heavy workloads. The integrated Cavium/Broadcom 57840S chipset with TOE and offloading capabilities ensures high throughput while minimizing CPU utilization for I/O-intensive functions like storage, live migration, and multi-tenant networking
