Key Features. Improve CPU Utilization with Lower Latency. The HPE Ethernet 10 Gb 2-port SFP+ QL41401 Adapter reduces CPU utilization & helps improve host virtual machine (VM) density & server efficiency using remote direct memory access (RDMA). It is supported by IWARP Ro CE & RoC Ev 2 protocols for VM migration & supports Microsoft SMB Direct. Delivers single root I/O virtualization (SR-IOV) with the ability to run a large number of virtual machines (VMs) per server which reduces the need for hardware & the resultant costs of space & power required by hardware devices Enhance Performance & Lower Power Consumption. The HPE Ethernet 10 Gb 2-port SFP+ QL41401 Adapter allows customers to use overlay networking which increases VM migration flexibility with minimal impact to performance & lower power usage with tunnel offloads (VXLAN NVGRE & GENEVE). Accelerates transmission of small packet I/O processing with data plane development kit (DPDK). .
