`
`TECHNICAL FIELD OF THE INVENTION
`
`to network storage
`This invention relates in general
`devices, and more particularly to a storage router and method
`for providing virtual local storage on remote SCSI storage
`devices to Fibre Channel devices.
`
`BACKGROUND OF THE INVENTION
`
`Typical storage transport mediums provide for a relatively
`small number of devices to be attached over relatively short
`distances. One such transport medium is a Small Computer
`System Interface (SCSI) protocol, the structure and operation
`ofwhich is generally well known as is described, for example,
`in the SCSI-1, SCSI-2 and SCSI-3 specifications. High speed
`serial interconnects provide enhanced capability to attach a
`large number of high speed devices to a common storage
`transport medium over large distances. One such, serial inter-
`connect is Fibre Charmel, the structure and operation of
`which is described, for example, in Fibre Channel Physical
`and Signaling Interface (FC-PH), ANSI X3.230 Fibre Chan-
`nel Arbitrated Loop (FC-AL), and ANSI X3 .272 Fibre Chan-
`nel Private Loop Direct Attach (FC-PLDA).
`Conventional computing devices, such as computer work-
`stations, generally access storage locally or through network
`interconnects. Local storage typically consists of a disk drive,

`
`tape drive, CD-ROM drive or other storage device contained
`within, or locally connected to the workstation. The worksta-
`tion provides a file system structure that includes security
`controls, with access to the local storage device through
`native low level block protocols. These protocols map
`directly to the mechanisms used by the storage device and
`consist of data requests without security controls. Network
`interconnects typically provide access for a large number of
`computing devices to data storage on a remote network
`server. The remote network server provides file system struc-
`ture, access control, and other miscellaneous capabilities that
`include the network interface. Access to data through the
`network server is through network protocols that the server
`must translate into low
