I know there have been similar questions asked over the last few months however looking at a Data Center Operations and know there are some really smart people out there that might be able to help.
Looking for some staffing best practices based on first hand experience and was hoping that there is some experience in this area that can provide "best practice" application:
Three High Availability (99.99% plus) Enterprise Level Data Centers geographically dislocated, one manned 24x7x365, one lights out, one co-location running HOT-HOT-HOT supporting a global community. More than 2,000 operating systems consisting of 95% Windows, 5% Linux and Solaris, 45% virtualized, more than 100TB storage. No desktop support, no Network Administration (administrated separately), running N+1 and serving more than 250 Billion page views annually.
Based on experience what has been your experience with Server to "Data Center System Administrator/Engineer" ratio?
Thanks in advance for your responses.
