Avanade is a rapidly expanding global IT consultancy firm with a growing number of professionals. Until recently, the IT department could not contain the equally impressive increase in servers. When Avanade deployed a virtualization solution with the Windows Server 2008 operating system and Hyper-V technology running on Sun x64 servers, the company gained the performance, reliability, and scalability to virtualize as many workloads as possible, including resource-intensive 64-bit applications. Over the next five years, Avanade expects to avoid U.S.$835,000 in hardware expenses and rack-space charges, and to slow storage growth by 58 percent. Today, the IT staff can provision test environments in hours instead of waiting weeks for new servers, enabling the IT department to more quickly respond to business requirements, including the development of a new disaster-recovery center.
