Ask the Expert: Cisco Data Center Virtual Machine Fabric Extender

03-28-2014 02:15 PM PST thru 04-11-2014 02:15 PM PST


Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco Data Center Virtual Machine Fabric Extender (VM-FEX) with Vishal Mehta and Ali Haider.

Cisco VM-FEX collapses virtual and physical networking into a single infrastructure. Data center administrators can now provision, configure, manage, monitor, and diagnose virtual machine network traffic and bare-metal network traffic within a unified infrastructure.

Cisco Data Center VM-FEX partitions the server adapter into multiple vNICs, and each vNIC is assigned to individual virtual machines.

The VM-FEX software extends Cisco fabric extender technology to the virtual machine with the following capabilities:

  • Each virtual machine includes a dedicated interface on the parent switch
  • All virtual machine traffic is sent directly to the dedicated interface on the switch
  • The software-based switch in the hypervisor is eliminated
