I have a question regarding VMWare in the data centre.
We currently have a two-site data centre configured as ne logical DC.
Within that DC, we run multiple VRF's to allow different companies to utilise the network infrastructure.
The VRF's are separated by firewalls (both FWSM and Checkpoint).
I am being pressed by our server guys who want to host a guest server from different companies (different VRF's) on the same VM Host server.
This approach bridges firewall DMZ interfaces and I do not want to do this.
However, VMWare claim that there virtual switch product provides an "air gap" between servers so there is no security risk.
Has anyone got an opinion on this?
