Hello, We have an iscsi target with one vhd file in it for our target database with multiple vm servers in it. it is better to have one vm server per vhd file for backup purposes or does it matter, should we put all our vm'd servers in one vhd file? Is there a performance increase/decrease with multiple servers in each vhd? We are trying to plan for this now as it will be diffcult to change later on.
I don't understand the question properly so this might be completly useless.
vhd is the MS hypervisor format is it not?
I don't know anything about vdh but it is my understanding it is the equivalent of a vmdk.
In vmware, each vm has at least one vmdk.
You can store multiple VMs (and thus their vmdk) into one LUN. Stick to 10 VMs to prevent locking issues. A good size for a LUN is 500Gb.
Mix workloads too if you can
