Abstract
A method according to one embodiment includes receiving an I/O request for data, and determining whether the I/O request refers to migrated or unmigrated data. Unmigrated data is data residing on a first portion of a drive array, the first portion being arranged in according to a first array configuration having at least a first parameter. Migrated data is data that has been migrated from the first portion to a second portion of the drive array, the second portion having a second array configuration having at least a second parameter. The method also includes using parameters corresponding to the first array configuration in response to determining that the requested data is unmigrated data. However, in response to determining that the requested data is migrated data, parameters corresponding to the second array configuration are used.
