Beware When Using Descriptive Names For VMM

Over the years I’ve seen lots of computer naming standards.  Some have used Simpsons or Tolkein character names, football player surnames, etc.  That has mainly because of laziness, but sometimes it’s to do with security-by-obscurity because “hackers then can’t figure the network out” Smile  Ooooooo-k then!  No need for defensive comments on that topic Smile

On the other extreme I’ve seen the likes of Dub-Lab-DC-1.  It couldn’t get much more descriptive without including the spec of the server.  You’ll need to be careful if creating a VMM server in this kind of network.  There’s a small, but important, note in TechNet article that describes the system requirements of System Center 2012 Virtual Machine Manager (VMM) with/without Service Pack 1 (SP1).

In addition to the normal rule of the computer name not exceeding 15 characters:

The computer name cannot contain the character string of –SCVMM-, but you can use the character string of SCVMM in the computer name. For example, the computer name can be SEASCVMMLAB, but the computer name cannot be SEA-SCVMM-LAB.

In other words:

  • Dub-Lab-SCVMM-1 is BAD.
  • Dub-Lab-SCVMM1 is good.  A single hyphen can be the difference between a successful day and a world of hurt.

Interestingly, neither Bing nor Google return any results for -SCVMM- for me.
