Abstract

A printed circuit assembly, along with a server and method incorporating such printed circuit assembly, are disclosed for determining a storage configuration for use in a computer system via a simple hardware change. The printed circuit assembly may comprise a paddle board slot for connection to a paddle board for determining a storage configuration; a bus coupled to the paddle board; and a southbridge coupled to the bus, the southbridge comprising signal lines coupled to the paddle board slot through the bus. The storage configuration of the printed circuit assembly may be determined via the paddle board when the paddle board is connected to the paddle board slot.

Claims

1. A printed circuit board comprising:

a paddle board slot for connection to a paddle board;

a bus coupled to said paddle board; and

a southbridge coupled to said bus, said southbridge comprising signal lines coupled to said paddle board slot through said bus;

wherein a signal line configuration of said paddle board determines a particular storage configuration of said printed circuit board by facilitating control of a storage device installed on said printed circuit board when said paddle board is connected to said paddle board slot.

2. The printed circuit board according to claim 1, wherein said paddle board is a SATA paddle board, wherein said storage device is a SATA hard disk, and wherein said southbridge controls said SATA hard disk by using said signal lines coupled to said paddle board slot via the connection of said SATA paddle board to said paddle board slot.

3. The printed circuit board according to claim 1, wherein said paddle board is a SAS paddle board comprising a SAS controller, wherein said storage device is a SAS hard disk, and wherein said SAS controller controls said SAS hard disk by using SAS signal lines coupled to said paddle board slot via the connection of said SAS paddle board to said paddle board slot.

4. A printed circuit board comprising:

a paddle board slot for connection to a paddle board;

a bus coupled to said paddle board; and

a storage device connector for coupling to said bus a storage device installed on said printed circuit board;

wherein a signal line configuration of said paddle board determines a particular storage configuration of said printed circuit board by facilitating control of said storage device when said paddle board is connected to said paddle board slot.

5. The printed circuit board according to claim 4, further comprising a southbridge coupled to said bus, wherein said southbridge comprises signal lines coupled to said paddle board slot through said bus, wherein said paddle board is a SATA paddle board, wherein said storage device is a SATA hard disk, and wherein said southbridge controls said SATA hard disk by using said signal lines coupled to said paddle board slot via the connection of said SATA paddle board to said paddle board slot.

6. The printed circuit board according to claim 4, wherein said paddle board is a SAS paddle board comprising a SAS controller, wherein said storage device is a SAS hard disk, and wherein said SAS controller controls said SAS hard disk by using SAS signal lines coupled to said paddle board slot via the connection of said SAS paddle board to said paddle board slot.

7. The printed circuit board according to claim 4, wherein said storage device is selected from at least one of a SATA hard disk, a SAS hard disk, and a solid-state hard disk.

8. A server comprising:

an enclosure;

a paddle board;

a storage device; and

a printed circuit board mounted within said enclosure, wherein said storage device is installed on said printed circuit board, and wherein said printed circuit board comprises;

a paddle board slot for connection to said paddle board;

a bus coupled to said paddle board; and

a southbridge coupled to said bus, said southbridge comprising signal lines coupled to said paddle board slot through said bus;

wherein a signal line configuration of said paddle board determines a particular storage configuration of said printed circuit board by facilitating control of said storage device when said paddle board is connected to said paddle board slot.

9. The server according to claim 8, wherein said paddle board is a SATA paddle board, wherein said storage device is a SATA hard disk, and wherein said southbridge controls said SATA hard disk by using said signal lines coupled to said paddle board slot via the connection of said SATA paddle board to said paddle board slot.

10. The server according to claim 8, wherein said paddle board is a SAS paddle board comprising a SAS controller, wherein said storage device is a SAS hard disk, and wherein said SAS controller controls said SAS hard disk by using SAS signal lines coupled to said paddle board slot via the connection of said SAS paddle board to said paddle board slot.

11. The server according to claim 8, wherein said storage device is selected from at least one of a SATA hard disk, a SAS hard disk, and a solid-state hard disk.

12. A method for determining a particular storage configuration for use in a computer system having a printed circuit board, said method comprising:

providing a paddle board;

installing a storage device on said printed circuit board; and

connecting said paddle board to a paddle board slot of said printed circuit board to determine said particular storage configuration of said printed circuit board by facilitating control of said storage device via a signal line configuration of said paddle board.

13. The method according to claim 12, further comprising operatively engaging a southbridge of said printed circuit board with said paddle board, said southbridge comprising signal lines coupled to said paddle board slot.

14. The method according to claim 12, further comprising operatively engaging said storage device with said paddle board.

15. The method according to claim 14, wherein said paddle board is a SAS paddle board comprising a SAS controller, wherein said storage device is a SAS hard disk, the method further comprising controlling said SAS hard disk by using SAS signal lines coupled to said paddle board slot via the connection of said SAS paddle board to said paddle board slot.

16. The method according to claim 12, further comprising:

operatively engaging a southbridge of said printed circuit board with said paddle board, said southbridge comprising signal lines coupled to said paddle board slot; and

operatively engaging said storage device with said paddle board.

17. The method according to claim 16, wherein said paddle board is a SATA paddle board, wherein said storage device is a SATA hard disk, the method further comprising controlling said SATA hard disk by using said signal lines coupled to said paddle board slot via the connection of said SATA paddle board to said paddle board slot.

18. The method according to claim 12, wherein said storage device is selected from at least one of a SATA hard disk, a SAS hard disk, and a solid-state hard disk.
