The HPE FlexFabric 10Gb 2-port 556FLR-T adapter is a dual port 10GBASE-T adapter for ProLiant Gen9 rack and Density Optimized servers in a FlexibleLOM form factor that provides full-featured, high performance, converged 10 Gb Ethernet that accelerates IT services and increases data center efficiency across a broad range of I/O intensive enterprise, cloud and Telco workloads. The HPE 556FLR-T Adapter, with two RJ-45 connectors, delivers full line-rate performance across all ports with low power consumption, utilizing CAT 6A UTP (or better) cabling with distances up to 100 meters and is backward compatible to existing 1000BASE-T infrastructure. It offers overlay network tunneling and storage capabilities that increase host efficiency and virtualization performance. The HPE FlexFabric 556FLR-T can provide up to 40 Gb/s of converged bi-directional Ethernet bandwidth, helping to alleviate network bottlenecks.
