Emulex Virtual Network Acceleration (VNeX) technology support
Emulex VNeX supports Microsoft supported network virtualization by using generic routing
encapsulation (NVGRE) and VMware-supported virtual extensible LAN (VXLAN). These technologies
create more logical LANs for traffic isolation that are needed by cloud architectures. Because these
protocols increase the processing burden on the server’s processor, the VFA5 has an offload engine
that is designed specifically for processing these tags. The resulting benefit is that cloud providers
can leverage the benefits of VxLAN/NVGRE while not being penalized with a reduction in the server’s
performance.

Advanced RDMA capabilities (planned for 1H/2014)
RDMA over Converged Ethernet (RoCE) delivers application and storage acceleration through faster
I/O operations with support for Windows Server SMB Direct and Linux NFS protocols.
You can deploy faster and manage less when you combine Virtual Fabric adapters (VFAs) and Host
Bus Adapters (HBAs) that are developed by Emulex.
IBM VFAs and HBAs that are developed by Emulex use the same installation and configuration
process, streamlining the effort to get your server running, and saving you valuable time. They also
use the same Fibre Channel drivers, reducing time to qualify and manage storage connectivity. With
Emulex's OneCommand Manager, you can manage IBM VFAs and HBAs that are developed by
Emulex through the data center from a single console.
