`ABSTRACT
`(57)
`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 :1 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 Fiber 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
`h SCSI
`d
`.
`60 62 64 Th
`storage space ont e
`storage ev1ces(
`,
`,
`).'
`e
`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.

`Applicants appreciate the Examiner’s allowance of or confirmation of Claims 1-8 of
`
`United States Patent No. 6,421,753. Applicants submit the record as a whole makes evident
`
`the reasons for allowance and that there are additional reasons for patentability not enumerated
`
`by the Examiner. While Applicants agree with the Examiner's reasons for patentability to the
`
`extent such reasons are consistent with the record as a whole (as Applicants understand them
`
`to be), Applicants do not acquiesce or agree to any characterization of the claims that place
`
`unwarranted limitations or interpretations upon the claims, especially to the extent such
`
`limitations or interpretations are inconsistent with the claim language, specification or prior
`
`prosecution history in this case.

`
`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 and 4), 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 specificationlstandard that is well known to one of ordinary skill in the art, where
`the NLLBP is used atthe router for communications with both the first and second transport medium. The SCSI protocollstandard is considered
`a NLLBP. TCPIIP, e.g., used in Ethernet communications, however, is not considered to be a NLLBP.
