VSUM is a free virtual appliance from Cisco that integrates into the vSphere Web Client. Once deployed, VSUM allows you to do the following actions from the web client:
- Deploy Nexus 1000v and Application Virtual Switch (AVS)
- Upgrade the 1000v and AVS
- Migrate virtual networking from vSwitch/VDS
- Monitor your 1000v/AVS environment
In other words, Cisco VSUM is a virtual appliance that is registered as a plug-in to VMware vCenter Server. The Cisco VSUM user interface is an integral part of VMware vSphere Web Client. The Cisco VSUM enables you to install, migrate, monitor, and upgrade the VSMs in high availability (HA) or standalone mode and the VEMs on ESX/ESXi hosts.
