Abstract

A storage card module having a front panel card component and a rear panel transition module disposed on a backplane in accordance with the Compact Peripheral Component Interconnect (CPCI) bus standard, wherein the front panel card component is provided with at least one Small Computer System Interface (SCSI) storage medium drive. Power is supplied to the SCSI drive from a CPCI bus connector on the backplane, whereas a user-defined I/O connector on the backplane provides interconnection between the drive and the SCSI bus that is coupled to an I/O controller via an interface formed on the real panel transition module. Bus cabling coupled via the user-defined I/O connector may be used to daisy-chain other SCSI-based cards, mass storage devices, or may be terminated. A power cable deriving power from the CPCI bus connector provides auxiliary power output via a rear panel power connector to such daisy-chained mass storage devices.

Claims

1. A modularized storage card apparatus, comprising:

a backplane having a front side and a rear side, said backplane conforming to the Compact Peripheral Component Interconnect (CPCI) bus standard, each of said front and rear sides having a CPCI bus connector and a user-defined connector disposed thereon;

a rear panel module coupled to said rear side of said backplane via said CPCI bus connector and said user-defined connector, said rear panel module having a first input/output (I/O) bus interface and a second I/O bus interface, said first I/O bus interface coupling to an I/O bus controller; and

a front panel card coupled to said front side of said backplane via said CPCI bus connector and said user-defined connector, said front panel card having at least one storage drive formed thereon, wherein said at least one storage drive receives power from said CPCI bus connector and is coupled to said first I/O bus interface via said user-defined connector.

2. The modularized storage card apparatus as set forth in claim 1, wherein said at least one storage drive comprises a Small Computer System Interface (SCSI) tape drive, and further wherein said I/O bus controller comprises a SCSI controller.

3. The modularized storage card apparatus as set forth in claim 1, wherein said at least one storage drive comprises a SCSI disk drive, and further wherein said I/O bus controller comprises a SCSI controller.

4. The modularized storage card apparatus as set forth in claim 1, wherein said at least one storage drive comprises a SCSI Compact Disc Read-Only Memory (CDROM) drive, and further wherein said I/O bus controller comprises a SCSI controller.

5. The modularized storage card apparatus as set forth in claim 1, wherein said at least one storage drive comprises at least one of a SCSI digital audio tape (DAT) drive and a quarter inch cartridge (QIC) tape drive, and further wherein said I/O bus controller comprises a SCSI controller.

6. The modularized storage card apparatus as set forth in claim 1, wherein said second I/O bus interface is disposed in an electrical conductive relationship with said first I/O bus interface via said user-defined connector and is coupled to a bus termination point.

7. The modularized storage card apparatus as set forth in claim 1, wherein said second I/O bus interface is disposed in an electrical conductive relationship with said first I/O bus interface via said user-defined connector and is coupled to an external SCSI device.

8. The modularized storage card apparatus as set forth in claim 7, wherein said external SCSI device comprises a mass storage device selected from the group consisting of a tape drive, a fixed disk drive, a magneto-optical disk drive, and a redundant SCSI controller.

9. The modularized storage card apparatus as set forth in claim 1, wherein said rear panel module includes an external power connector for supplying power to another SCSI device, and further wherein said external power connector receives power distributed from said CPCI bus connector via a distribution path that is routed through said user-defined connector.

10. A system manager shelf for use in a signaling server disposed in a telecommunications network, comprising:

a backplane having a plurality of slots formed on a front side and a rear side of said backplane;

a storage card having a first storage drive and a second storage drive formed thereon, said storage card occupying one of said plurality of slots on said front side of said backplane; and

a processor card occupying another one of said plurality of slots on said front side of said backplane, said processor card controlling said storage card,

wherein said processor card and said storage card communicate via respective transition modules associated therewith and disposed on said rear side of said backplane.

11. The system manager shelf for use in a signaling server as set forth in claim 10, wherein said first storage drive comprises a Small Computer System Interface (SCSI) tape drive.

12. The system manager shelf for use in a signaling server as set forth in claim 11, wherein said second storage drive comprises a SCSI disk drive.

13. The system manager shelf for use in a signaling server as set forth in claim 12, wherein said transition modules are coupled using a SCSI cable.

14. The system manager shelf for use in a signaling server as set forth in claim 10, wherein said processor card comprises a Peripheral and Load Computing Element (PLCE).

15. The system manager shelf for use in a signaling server as set forth in claim 10, wherein said backplane comprises a Compact Peripheral Component Interconnect (CPCI) backplane having a CPCI bus connector portion and a user-defined I/O connector portion in each of said slots.

16. The system manager shelf for use in a signaling server as set forth in claim 10, wherein said first and second storage drives receive power from said CPCI bus connector portion.

17. The system manager shelf for use in a signaling server as set forth in claim 10, wherein said first and second storage drives are interfaced with said transition module associated with said storage card via said user-defined I/O connector portion.
