The objective of reducing the number of servers achieves two goals: reign in server sprawl and reduce energy consumption. As a company that has grown quickly in a short amount of time (to a USD 2 billion dollar company in just 10 years), servers were often deployed to fill a pressing need, resulting in approximately 1000 corporate servers geographically dispersed in many different sites and data centers. Not only were these servers becoming harder to keep track of and manage, but their proliferation was straining the basic resources of the data centers – they were running out of power and space.
The company took a hard look at their data center strategy and decided it was time to make some changes to improve their efficiency. To do this, IT looked at virtualization, which enables a single physical server to house multiple, independent operating systems and applications that are logically separated. Virtualization enables better data consumption and overall server utilization, ultimately enabling server consolidation that results in power, cooling, space and operational management efficiencies.
