Virtualization
Virtual Fabric vNICs (virtual NICs) with Ethernet, iSCSI, or FCoE traffic on vNICs
Virtual link aggregation groups (vLAGs)
802.1Qbg Edge Virtual Bridging (EVB) is an emerging IEEE standard for allowing networks to become
virtual machine (VM)-aware.
Virtual Ethernet Bridging (VEB) and Virtual Ethernet Port Aggregator (VEPA) are mechanisms for
switching between VMs on the same hypervisor.
Edge Control Protocol (ECP) is a transport protocol that operates between two peers over an
IEEE 802 LAN providing reliable, in-order delivery of upper layer protocol data units.
Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) allows centralized
configuration of network policies that will persist with the VM, independent of its location.
EVB Type-Length-Value (TLV) is used to discover and configure VEPA, ECP, and VDP.
VMready support
Up to 2,048 virtual entities (VEs)
Automatic VE discovery
Up to 32 local or distributed VM groups for VEs
NMotion™ feature for automatic network configuration migration
