Abstract
A storage system comprises a plurality of enclosures and a storage controller. Each enclosure comprises at least one processing device and a plurality of drives configured in accordance with a redundant array of independent disks (RAID) arrangement. The storage controller obtains data pages associated with at least one input-output request and provides the obtained data pages to the at least one processing device of a given enclosure. The storage controller issues a command to the at least one processing device of the given enclosure to perform at least one operation based at least in part on the obtained data pages. The at least one processing device of the given enclosure receives the obtained data pages from the storage controller, calculates RAID parities based at least in part on the received data pages, and stores the data pages and RAID parities on the plurality of drives according to the RAID arrangement.
