Abstract
A data storage array may be made up of several storage devices, each of which may contain array metadata that may allow portions of the storage array to be used. A system may have a file system manager that may receive and respond to file system commands and a storage device manager that may store data on the several storage devices. Array metadata defining where data is stored within the storage array is stored on each device within the array. A policy engine may identify data to be stored on the array and determine if the data contains array metadata or other types of data and may store the data on every device, devices having specific characteristics, two or more devices, or one device.
