Challenges:
• Underutilized hardware
• Excessive power consumption
• Expensive space across datacenter and branch offices
“We expect to consolidate an additional 75 servers using Hyper-V, which will lead to a cost savings of more
than $325,000 annually. By the time we hit our fifth virtual machine, we’ve usually paid for the host.
Long term, we will be able to reduce our total data center holdings by 75 percent—from nearly 400 servers
to fewer than 100 servers.”
Robert McShinsky Senior Systems Administrator, Dartmouth-Hitchcock Medical Center
