Abstract
A method of managing storage resources is provided. The method includes (a) storing data in an array of storage extents on respective storage drives of a plurality of storage drives, the array of storage extents having a first level of redundancy; and (b) in accordance with a storage management policy, adjusting the array of storage extents to have a second level of redundancy by changing the array of storage extents from having a first number of storage extents on respective storage drives to having a second number of storage extents on respective storage drives, the second level of redundancy providing a different tolerance for failure than the first level of redundancy. An apparatus, system, and computer program product for performing a similar method are also provided.
