monitoring of the data center environment in order to
guide key decisions on both hardware and operations.
2) Data Center Modelling: computational fluid dynamics
studies were performed to study and optimize the subfloor supplied air flow.
3) Server Replacement: energy awareness in major and
minor equipment acquisitions, as demonstrated in
three key purchases in which major energy savings
were achieved while simultaneously increasing compute capacity.
4) Rack-based Chilled Water Cooling System: employing cooling systems that more efficiently deliver
cooling to the servers.
