22 Mar 12 09 - 10GB nic in VM
Posted on 2012-03-12
I have a nic that supports advanced vm functionality - it even has a Virtulization server profile which turns on or sets all the advanced settings to those suited for hyper -v. The problem is that I am not sure if I should share the interface with the host / management server. I have a 20TB array on the VM, as a pass through disk, plus I have 20TB array on the host server - which I use to backup the array in the VM - so having the adapter shared is great because I get 10GB between the machines. The thing is I would like to have 2 Virtual machines - each with their own 20TB array - for example \\fserver1 and \\fserver2 - but I only have a single 10GB nic - is it advisable to attach the same nic to both VMs? I cant see any problem with it but I also cant find any online documentation for this. I imagine if I had 3 10GB nics in the host - I could use 1 for the host - and 1 each for the VM's - but then I have to pass all traffic through the physical 10GB switch - where using the Virtual switch makes more sense to me. Also - if I had only 2 10GB nics, and dedicated those to 2 VMs - would I then share both interfaces with the host so when I want to backup either VM to the host array I get 10GB connectivity without having to use the physical switch?
