Server sprawl is a situation which results into poor hardware component utilization, compromised system and software security, and high energy consumption. This situation occurs when multiple servers within a data center are under-utilized or partially used, occupies more space, computing, power, cooling, and other resources that can be justified to their work capacity. A server sprawl usually occurs in a data center housing more servers than required. The other cause for server sprawl may arise when a large number of low-end servers are utilized and dedicated to a single application.
There are various techniques used to minimize server sprawl, among these, computer virtualization is the known one. To mitigate server sprawl, many of the businesses have started opting for server consolidation measures, like blade servers to slash down the expenses on management & maintenance, and maximizing return on investment.
