I'm not sure what part of my comment made you draw that conclusion. This was a science team and we used servers mostly for scientific computations. Sysadmins jobs was to operate and maintain the servers e.g. make jobs run, upgrade, patch, fix, etc. Virtualization massively simplified this, and automation decreased human intervention. With 250 we were definitely running bigger tasks faster e.g. a project that required 3 months of computing now takes 2 weeks instead.
