Abstract
A method for communication between an initiator system and a block storage cluster may include receiving a first input/output (I/O) request from the initiator system. The method may also include sending a referral response from a first storage system included in a plurality of storage systems of the block storage cluster to the initiator system when data associated with the first I/O request is stored in more than one storage system of the plurality of storage systems of the block storage cluster. Additionally, the method may include directing a referral I/O to the first storage system and the second storage system for transferring data to or transferring data from the first storage system and the second storage system, and transferring data associated with the referral I/O to or transferring data associated with the referral I/O from the first storage system and the second storage system.
