Small computer system interface input output (SCSI IO) referral

摘要

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.

1. A method for data transfer via a storage cluster, the method comprising:
receiving a first command from an initiator directed to a first storage system of the storage cluster, wherein the first command is directed to data stored by the storage cluster; providing a first portion of the data from the first storage system to the initiator based on the first portion of the data being stored by the first storage system; determining, by the first storage system, that a second portion of the data is stored by a second storage system of the storage cluster; and providing a referral response to the initiator based on the second portion of data being stored by the second storage system, wherein the referral response is configured to cause the initiator to provide a second command from the initiator directed to the second storage system.
