VSM and VEM modules

Information about modules

Cisco nexus 1000 V manages a data center defined by a Virtualcenter. Each server in the data center is represented as a module and can be managed as if it were a module in a physical Cisco switch.

The Cisco nexus 1000 V implementation has 2 parts:

• Virtual supervisor module (VSM)-this is the control software of the Cisco nexus 1000 V distributed virtual switch. It runs on a virtual machine (VM) and is based on Cisco NX-OS software.

• Virtual Ethernet module (VEM)-This is the part of Cisco nexus 1000 V that actually switches data traffic. it runs on a VMware ESX 4.0 host. several vems are controlled by one VSM. all the vems that form a switch domain shoshould be in the same virtual data center as defined by Vmware Virtualcenter.
