Abstract
A method for communication between an initiator system and a block storage cluster may include receiving a first command at a first storage system included in a plurality of storage systems of the block storage cluster. The method may also include transmitting a referral response from the first storage system to the initiator system when at least a portion of the data associated in the first command is stored by a second storage system. The method may further include obtaining a segment start value and a corresponding port identifier based on the referral response, and directing a second command to at least a second storage system included in the plurality of storage systems of the block cluster.
