Always seeking to improve efficiencies and patient care, Temple, Texas-based Scott & White Memorial Hospital deployed over the last 10 years an array of advanced applications, such as medical imaging systems and an internally-developed electronic medical records system. By dedicating a server to each application, Scott & White was under utilizing the servers' capacities, causing inefficiencies particularly among platforms that did not generate much network traffic. Scott & White implemented "virtual machines" on its servers and bolstered its SAN, starting with the two redundant Brocade 6140 directors comprising the system's core. Thanks to the scalability of these systems, administrators simply installed ASIC cards, which doubled their speed to 4 Gbit/sec and added ports. By bolstering its SAN and running some 200 "virtual machine" servers, Scott & White consolidated 200 physical servers down to 20. It eliminated the increasing maintenance expenses of 180 servers as well as the energy costs to power and cool the devices.
