Virtualization
Virtual NIC (vNIC)
Ethernet, iSCSI, or FCoE traffic is supported on vNICs
Unified fabric port (UFP)
Ethernet or FCoE traffic is supported on UFPs
Supports up to 256 VLAN for the virtual ports
Integration with L2 failover
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
Switch partitioning (SPAR)
SPAR forms separate virtual switching contexts by segmenting the data plane of the
switch. Data plane traffic is not shared between SPARs on the same switch.
SPAR operates as a Layer 2 broadcast network. Hosts on the same VLAN attached to a
SPAR can communicate with each other and with the upstream switch. Hosts on the
same VLAN but attached to different SPARs communicate through the upstream switch.
SPAR is implemented as a dedicated VLAN with a set of internal compute node ports
and a single external port or link aggregation (LAG). Multiple external ports or LAGs are
not allowed in SPAR. A port can be a member of only one SPAR.
Converged Enhanced Ethernet
Priority-Based Flow Control (PFC) (IEEE 802.1Qbb) extends 802.3x standard flow control to
allow the switch to pause traffic based on the 802.1p priority value in each packet's VLAN tag.
Enhanced Transmission Selection (ETS) (IEEE 802.1Qaz) provides a method for allocating link
bandwidth based on the 802.1p priority value in each packet's VLAN tag.
Data Center Bridging Capability Exchange Protocol (DCBX) (IEEE 802.1AB) allows neighboring
network devices to exchange information about their capabilities.
