`ABSTRACT
`.
`.
`A storage router and storage network provrde Virtual local
`storage on remote storage devices. A plurality of devices are
`connected to a first transport medium. In one embodiment, a
`storage router maintains a map to allocate storage space on
`the remote storage devices to devices connected to the first
`transport medium by associating representations of the
`devices connected to the first transport medium with repre-
`sentations ofstorage space on the remote storage devices. The
`storage router controls access from the devices connected to
`the first transport medium to the storage space on the remote
`storage devices in accordance with the map and allows access
`from devices connected to the first transport medium to the
`remote storage devices using native low level block protocol.
