"We're at the point now that if our primary file server (where the majority of our files are stored) were to go down for a day, it would have a huge business impact," says Larry Penrod, network manager at Barkley. With the goal of getting to 100 percent availability, Penrod developed a plan that began with creating virtual copies of nearly all of the servers using HP's blade hardware, VMware's virtualization software and a variety of existing storage platforms. Moving to HP blades has allowed the firm to drastically reduce its server footprint in the data center.
