BENEFITS
Designed for Next-Gen Server Virtualization
Designed for Next-Gen Server Virtualization
The 8400 Series Converged Network Adapters support today’s most
compelling set of powerful networking virtualization features: SR-IOV,
switch-independent NIC partitioning (NPAR), tunneling offloads (VXLAN and
NVGRE), and industry-leading performance, thus enhancing the underlying
server virtualization features.
