After Dammions Darden arrived as the new senior systems administrator for the city of Garland, Texas, he knew that the 50 to 60 physical hosts for this 234,000-person city outside of Dallas were not running nearly as efficiently as they could be. Some had excess capacity, others were running way too hot.
Traditionally if apps are slow and virtual machines need more memory the easy answer is an unfortunate one: Throw more hardware at the problem. But Darden wasn’t satisfied with that. While roaming the expo floor at VMworld two years ago he stumbled across VMTurbo, a company that specializes in analyzing virtual environments.
