  • Publication number: 20050021889
    Abstract: A system and method are disclosed for processing commands to network target devices through a SCSI router in a Fibre Channel network having a plurality of Fibre Channel hosts. The system and method are implemented in the SCSI router and include receiving a command from one of the plurality of Fibre Channel hosts and, if the command is for a transfer of data larger than a threshold size, streaming the data to the target device. If a preset size memory block is free, a data block is requested from the Fibre Channel host that issued the command. Otherwise, the method of this invention waits to request the data block until the preset size memory block is free. The SCSI router receives the data block and stores the data block in a FIFO queue. The method of this invention repeats until an initial number of data blocks are stored in the FIFO queue. The command and the first data block received are forwarded to the network target device.
