Abstract
A storage assembly includes a physical expander for connection in use to two or more SCSI initiators, and two or more storage devices, wherein the expander is controlled such that it presents plural virtual expanders. A method for connecting two or more storage devices to two or more SCSI initiators within a storage assembly, includes providing a physical expander for connection in use to the two or more SCSI initiators, and two or more storage devices, and controlling the single expander such that it presents plural virtual expanders.
Claims21
A storage assembly, comprising:
- a physical expander for connection in use to two or more SCSI initiators, and two or more storage devices, wherein the expander is controlled such that it presents plural virtual expanders.
A storage assembly whereby the method of attaching multiple storage devices to a midplane is the same as attaching a single storage device to the same midplane.
A physical expander for arrangement within a storage assembly and for connection in use to two or more SCSI initiators and two or more storage devices, wherein the expander is controlled or controllable such that it presents plural virtual expanders.
A method for connecting two or more storage devices to two or more SCSI initiators within a storage assembly, the method comprising:
- providing a physical expander for connection in use to the two or more SCSI initiators, and two or more storage devices, and
- controlling the single expander such that it presents plural virtual expanders.
A sled for use in a storage assembly, the sled comprising:
- a carrier arranged to carry plural disk drives;
- and
- a physical expander for connection in use to two or more SCSI initiators and two or more storage devices provided in use on the carrier, wherein the expander is controlled or controllable such that it presents plural virtual expanders.
