At our TechNet Event in Kansas City a couple of months ago, Travis asked:
“How many virtual machines can a single VMM instance manage?”
“But how many are supported?”
Ah.. well, that’s simply a matter of how many Microsoft was able to test and verify. Currently the supported number is 400 virtualization hosts, and 8,000 virtual machines. But that isn’t a hard-limit as far as what is possible given the proper hardware. With the hardware that they had at the time, those were the numbers they decided they could officially support.
”Oh.. that was for SCVMM 2008? What about the System Center 2012 version?”
I confess.. I wasn’t able to find any official statement on how many we support in the soon-coming version. When I find that – or if you find it and let me know in the comments – I will update this post.
