Someone asked me recently what are the differences between Distributed Virtual Switch and the Cisco Nexus 1000v?
As I have only used the 1000v in lab environments my highlevel knowledge was a little rusty.
This is what I found as being available in the 1000v and not the VDS:
- With the Nexus 1000v you get a IOS interface that will allow network managers to manage the virtual network infrastructure with the same features as they already use to manage the physical network.
- Port profile – As that VM moves from server to server with VMotion, the port profile follows it. All security and network configurations, stay with the VM as it travels from server to server. Enabling security policies you would traditionally find in the physical servers to be applied to VMs
- QOS (Quality Of Service)
- Switched Port Analyser
- And many more…
Much more on the features of the 1000v can be found http://www.cisco.com/en/US/products/ps9902/index.html
The VDS is a big step forward from the single vSwitch model with features like:
- Central Management
- Network Aware Vmotion
- Private VLANS
