HPE 581201-B21 Ethernet 10Gbps NC550SFP Dual Port PCIe x8 Network Adapter For ProLiant Generation6 Generation7 Servers (Refurbished - Grade A with 30 Days Warranty)

The HPE Ethernet 10Gb 2-port SFP+ Adapter provides hardware offloads which free CPU cycles to run application workloads rather than virtual network transport processing.

Addresses the increasing demand for an overlay network, enabling superior performance by introducing advanced NVGRE, VXLAN, and GENEVE hardware offload engines.

Decouples the overlay network layer from the physical NIC performance, thus achieving native performance in the new network architecture.

Delivers low latency and high performance over Ethernet networks with RoCEv1 and RoCEv2 for faster storage access.

Frees up CPU cycles and allow more processing power to be used for the application instead of for moving data.

The HPE 581201-B21 Ethernet 10 Gbps Dual Port SFP+ Network Adapters have dual 2 x 10Gb Ethernet - 2 ports to connect desktop and server systems to the network. This 10 Gbps dual port SFP+ adapter has 30 Days Warranty.
