Abstract
The present invention is a method for communication between an initiator system and a block storage cluster. The method includes receiving a command at a first storage system of a block storage cluster. The command is transmitted by the initiator system to the first storage system via a network and includes a request for data. The method further includes transferring the stored data from the first storage system to the initiator system via the network when data requested in the data request is stored by the first storage system. The method further includes transmitting a referral response from the first storage system to the initiator system when a portion of the data requested in the data request is not stored by the first storage system, but is stored by a second storage system of the block storage cluster. The referral response indicates to the initiator system that: a) not all of the requested data was transferred; and b) that the second storage system stores the portion of the requested data.
