On a global level, IT organizations are striving to transform IT to increase productivity, control costs, and improve efficiency. This has given a boost to server virtualization initiatives that can help achieve a more efficient, business-ready infrastructure. However, server virtualization creates a series of storage challenges, such as poor storage capacity utilization and increased infrastructure complexities. It also places additional demands on data management. These challenges, if not addressed, will decrease and even nullify its benefits. Dealing with the difficulties of provisioning storage, migrating data, expanding storage capacity, and managing diverse storage resources in a virtualized infrastructure can be frustrating and inefficient.
