`ABSTRACT
`
`A storage router (56) and storage network (50) provide
`virtual local storage on remote SCSI storage devices (60, 62,
`64) to Fiber Channel devices. A plurality of Fiber Channel
`devices, such as workstations (58), are connected to a Fiber
`Channel
`transport medium (52), and a plurality of SCSI
`storage devices (60, 62, 64) are connected to a SCSI bus
`transport medium (54). The storage router (56) interfaces
`between the Fibre Channel transport medium (52) and the
`SCSI bus transport medium (54). The storage router (56)
`maps between the workstations (58) and the SCSI storage
`devices (60. 62, 64) and implements access, controls for
`storage space on the SCSI storage devices (60, 62, 64). The
`storage router (56) then allows access from the workstations
`(58) to the SCSI storage devices (60, 62. 64) using native
`low level, block protocol in accordance with the mapping
`and the access controls.

`
`Claims 1-14 are allowed.
`
`The prior art disclosed by the patent owner and cited by the Examiner fail to teach or suggest, alone or in combination, all the limitations of the ‘
`independent claims (claims 1, 7 and 11), particularly the map/mapping feature which is a one-to—one correspondence, as given in a simple table,
`the map physically resident on a router, whereby the router forms the connection between two separate entities over different transport mediums,
`such that neither entity determines where data is to be sent, but rather, the router solely dictates where the data will be sent; also the “NLLBP"
`feature refering to a fundamental low level protocol defined by a specification/standard that is well known to one of ordinary skill in the art, where
`the NLLBP is used at the router for communications with both the first and second transport medium. The SCSI protocol/standard is considered
`a NLLBP. TCP/IP, e.g., used in Ethernet communications, however, is not considered to be a NLLBP.
