Abstract: The present invention is a method for accelerating proxy Input/Output (proxyI/O). The method includes the step of receiving a command at a primary target storage system. The primary target storage system may be part of a clustered storage array. The command may be a command which was transmitted by an initiator system via a storage area network, and may include a request for data. The method further includes the step of forwarding the command to a session layer of the primary target storage system. Further, when a virtualization layer of the primary target storage system determines that a portion of the data requested in the data request is not stored by the primary target storage system, but is stored by a proxy target storage system included in the plurality of storage systems, the method further includes providing a proxyIO request to a proxy initiator of the primary target storage system.

Abstract: A method and/or system may be configured to receive an input/output (I/O) request from an initiator system, add priority information to a multiple path referral for each port on which data can be accessed, selectively omit ports on which data may be accessed, transmit the multiple path referral from the target to the initiator, and/or choose a path on the initiator with the highest performance.

Abstract: The present invention is a method for providing multi-pathing via Small Computer System Interface Input/Output (SCSI I/O) referral between an initiator and a storage cluster which are communicatively coupled via a network. The method includes receiving an input/output (I/O) at a first target device from the initiator via the network. The I/O includes a data request.
