Desktop and server virtualization have brought many benefits to the data center. These two initiatives have allowed IT to respond quickly to the needs of the organization while driving down IT costs, physical footprint requirements and energy demands. But there is one area of the data center that has actually increased in cost since virtualization started to make its way into production… storage. Because of virtualization, more data centers need flash to meet the random I/O nature of the virtualized environment, which of course is more expensive, on a dollar per GB basis, than hard disk drives. The single biggest problem however is the significant increase in the number of discrete storage systems that service the environment. This “storage sprawl” threatens the return on investment (ROI) of virtualization projects and makes storage more complex to manage.
