Not all storage arrays are created equal when it comes to provisioning storage capacity. This Gartner report explains why dynamic volume expansion is one of the most important differences among today's storage products. In a time when differences in disk arrays are mostly in their ability to scale, dynamic volume expansion remains a difference that can significantly affect the amount of time that storage administrators spend provisioning storage to deal with application growth. Enterprises should ask vendors to explain the process for provisioning and expanding volumes for each critical application, and then use this information as part of the decision process in purchasing an array.
