I'm currently planning to deploy 1500 Windows 7 PCs using Provisioning in a span of two weeks. Being at a University we have a short time window to deploy updated images between summer and fall semsters. To meet our schedule and classroom/lab availability I'd like to be able to deploy 100 to 200 machines at a time.
In our limited deployment tests it appears that the "Deploy Image" step in the provisioning template is going to be a limiting factor in the number of machines that can be imaged at one time. This is because the image is transfered via a WinPE/network drive mapping and each machine is a seprate file transfer session.
I've read some vague articles regaring multicast image deployment and provisioning but I was hopeing to hear an explicit answer and strategy to overcome this. My investigation seems to point that Multicast Image depoloyment is only possible using OSD and not provisioning. Also because the image file and location must be explicitly specified in the provisioning template you cannot easily distribute the image file to local representatives to share the network load.
I'd truely appreciate any insight others can provide .
