HPE 700076-B21 FlexFabric 20 Gb 2-Port 630M Adapter
Overview
The HPE 700076-B21 is a dual-port 20 Gigabit Ethernet mezzanine adapter designed specifically for HPE blade servers, particularly in ProLiant Gen8 and Gen9 environments using the blade-server architecture. It offers two full-line-rate 20 Gb/s ports via a mezzanine slot interface, enabling high-bandwidth uplinks and converged network, storage, and virtualization traffic for blade-based compute nodes. The adapter supports advanced features such as FCoE, SR-IOV, jumbo frames, and teaming, making it suitable for virtualised hosts, high-density compute environments, and converged infrastructure where network bandwidth is critical. Installed via the blade server's mezzanine bay, it preserves standard expansion slots and integrates seamlessly into the broader HPE FlexNetwork ecosystem, providing a scalable path for 20 Gb Ethernet connectivity in enterprise blade deployments.
