Title:
METHOD AND APPARATUS FOR CONCURRENTLY PROCESSING SCSI COMMANDS
Document Type and Number:
WIPO Patent Application WO/2017/063507
Kind Code:
A1
Abstract:
A method and corresponding apparatus for concurrently processing small computer system interface (SCSI) commands. The method comprises the steps of: S1, when an LUN queue in a first stage is non-null, acquiring an LUN corresponding to a current queue head in the LUN queue in the first stage, and deleting the current queue head in the LUN queue in the first stage after the LUN is acquired; and S2, when an SCSI command queue that is in a second stage and that is corresponding to the acquired LUN is non-null or satisfies a first preset condition, sequentially processing SCSI commands in the SCSI command queue in the second stage, and returning to step S1 when the SCSI command queue in the second stage is null or satisfies a second preset condition. By means of the method and the apparatus, SCSI commands can be concurrently processed, accordingly the CPU usage is reduced, performance of a storage system is improved, and it is ensured that the SCSI commands are delivered to a bottom layer for processing according to a command reception order.
