    HPE 640FLR-SFP28 Network Adapter Product Description

    The HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 adapter for ProLiant Gen9 rack servers provides full-featured,high performance,converged 25 Gb Ethernet that accelerates IT services and increases data center efficiency across a broad range of I/O intensive enterprise,cloud and Telco workloads.

    It offers a rich set of offload technologies including overlay network tunneling and storage as well as RDMA over Converged Ethernet (RoCE) capabilities that increase host efficiency and virtualization performance.

    The HPE Ethernet 640FLR-SFP28 can provide up to 100 Gbps of converged bi-directional Ethernet bandwidth,helping to alleviate network bottlenecks. This adapter can also run at 10 Gb for customers who have not changed the infrastructure/switches to 25 Gb yet.
