Do you need an adapter that is big on capability and small on CPU utilization?

The HPE Ethernet 10Gb 2-port 537SFP+ Adapter has been designed to efficiently deliver high performance, low latency and minimal CPU utilization by offloading many I/O processing within the adapter. Low latency dramatically improves application performance and frees up CPU resources in the host allowing it to do more important tasks

Key Features

Improve Application Performance

HPE Ethernet 10Gb 2-port 537SFP+ Adapters offload packet processing to reduce CPU utilization with tunnel offloads (VXLAN and NVGRE). Now you can distribute network traffic across CPU cores in your data center.

Speed up packet processing to service more I/O requests by utilizing data plane development kit (DPDK) feature.

Increase I/O Bandwidth for Workload Intensive Applications

HPE Ethernet 10Gb 2-port 537SFP+ Adapters deliver single root I/O virtualization (SR-IOV) which increases virtual network performance while decreasing CPU utilization.
