Abstract
A method for communication between an initiator system and a storage cluster. The method comprises receiving an initial I/O request from the initiator system to a first storage system; providing a referral response from the first storage system to the initiator system, the referral response providing information for directing the initiator system to a second storage system; notifying the second storage system regarding the referral response via a prefetch notice, the prefetch notice including an operation type and address information for accessing requested data; when the initial I/O request is a read request, prefetching at least a portion of the requested data stored in the second storage system in to a cache; receiving a second I/O request from the initiator system to the second storage system; and providing to the initiator system the portion of the prefetched data from the cache of the second storage system.
