ABSTRACT

A

storage

router

(56)

and

storage

network

(50)

provide

Virtual

local

storage

on

remote

SCS1

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

SCS1

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

SCS1

bus

transport

medium

(54).

The

storage

router

(56)

maps

between

the

workstations

(58)

and

the

SCS1

storage

devices

(60,

62,

64)

and

implements

access,

controls

for

storage

space

on

the

SCS1

storage

devices

(60,

62,

64).

The

storage

router

(56)

then

allows

access

from

the

workstations

(58)

to

the

SCS1

storage

devices

(60,

62,

64)

using

native

low

level,

block

protocol

in

accordance

with

the

mapping

and

the

access

controls.
