Abstract

A reduced-depth rack server for a reduced depth rack includes a data storage device rotated a quarter turn within a carrier. An interposer cable connects at one end to a laterally presented electrical connector of the data storage device and presents another connector to an end that is inserted inwardly into a rack server chassis to electrically connect with a backplane of the reduced-depth rack server. In one embodiment, a data storage assembly of the data storage device, carrier and interposer cable is inserted from a front end of the chassis. In one embodiment, the data storage assembly is inserted from a top of the chassis to facilitate airflow.

Claims

1. A data storage assembly for a reduced-depth rack server, the data storage assembly comprising:

a data storage device having at least one electrical connector on a front end; and

a carrier comprising;

a tray structure having a service panel attached to two opposed side panels and a bottom panel, the tray structure sized to receive a longest dimension of the data storage device in a sideways orientation with the at least one electrical connector proximate to a selected lateral panel; and

an interposer cable having a first electrical connector electrically connected to the at least one electrical connector of the data storage device and having a second electrical connector attached to one of the tray structure and the data storage device directed towards an insertion end of the data storage assembly in an orientation opposite to the service panel, the second electrical connector to electrically connect with a backplane of a reduced-depth rack server in response to the tray structure being inserted in a rack server chassis.

2. The data storage assembly of claim 1, wherein at least a portion of the second electrical connector overlays one of a top and a bottom surface of the data storage device.

3. The data storage assembly of claim 1, wherein the second electrical connector comprises Serial Attached Small Computer System Interface (SAS) connector of less than 8 mm stack height.

4. The data storage assembly of claim 1, wherein the interposer cable comprise a flexible cable having a printed circuit board (PCB) of less than 0.06 mm thickness.

5. The data storage assembly of claim 1, wherein the service panel of the carrier comprises a screw mount.

6. The data storage assembly of claim 1, wherein the data storage device comprises a 2.5 inch hard disk drive.

7. An information handling system comprising:

a reduced-depth rack server for a reduced depth rack, the reduced-depth rack server comprising rack server chassis that contains a backplane and including;

a data storage assembly comprising;

a data storage device having at least one electrical connector on a front end; and

a carrier comprising;

a tray structure having a service panel attached to two opposed side panels and a bottom panel, the tray structure sized to receive the data storage device in a sideways orientation with the at least one electrical connector proximate to a selected lateral panel;

an interposer cable having a first electrical connector electrically connected to the at least one electrical connector of the data storage device and having a second electrical connector attached to one of the tray structure and the data storage device directed towards an insertion end of the data storage assembly in an orientation opposite to the service panel to electrically connect with the backplane of the reduced-depth rack server in response to the tray structure being inserted.

8. The reduced-depth rack server of claim 7, wherein at least a portion of the second electrical connector overlays one of a top and a bottom surface of the data storage device.

9. The reduced-depth rack server of claim 7, wherein the second electrical connector comprises Serial Attached Small Computer System Interface (SAS) connector of less than 8 mm stack height.

10. The reduced-depth rack server of claim 7, wherein the interposer cable comprise a flexible cable having a printed circuit board (PCB) of less than 0.06 mm thickness.

11. The reduced-depth rack server of claim 7, wherein the service panel of the carrier comprises a screw mount.

12. The reduced-depth rack server of claim 7, wherein the data storage device comprises a 2.5 inch hard disk drive.

13. The reduced-depth rack server of claim 7, wherein the backplane comprises a hot pluggable bay to receive the insertion end of the data storage assembly.

14. A method of making a reduced-depth rack server, the method comprising:

forming a tray structure of a carrier having a service panel attached to two opposed side panels and a bottom panel;

inserting a longest dimension of a data storage device in a sideways orientation with at least one electrical connector of the data storage device proximate to a selected lateral panel;

electrically connecting a first electrical connector of an interposer cable to the at least one electrical connector of the data storage device; and

attaching a second electrical connector attached to one of the tray structure and the data storage device directed towards an insertion end of the data storage assembly in an orientation opposite to the service panel and aligned to electrically connect with a backplane of a reduced-depth rack server in response to the tray structure being inserted in a rack server chassis.

15. The method of claim 14, wherein attaching the second electrical connector further comprises overlaying at least a portion of the second electrical connector to one of a top and a bottom surface of the data storage device.

16. The method of claim 14, further comprising:

attaching a backplane to the rack server chassis a reduced-depth rack server; and

inserting the tray structure to electrically connect the second electrical connector of the interposer cable to the backplane.

17. The method of claim 16, further comprises providing a hot pluggable bay of the backplane to receive the insertion end of the data storage assembly.

18. An information handling system comprising:

a top-accessible rack server having a reduced-height, the top-accessible rack server comprising rack server chassis that contains a backplane on a bottom panel and including;

a data storage assembly comprising;

a data storage device having at least one electrical connector on a front end; and

a carrier comprising;

a tray structure having a service panel attached to two opposed side panels and a bottom panel, the tray structure sized to receive the data storage device in a sideways orientation with the at least one electrical connector proximate to a selected lateral panel;

an interposer cable having a first electrical connector electrically connected to the at least one electrical connector of the data storage device and having a second electrical connector attached to one of the tray structure and the data storage device directed towards an insertion end of the data storage assembly in an orientation opposite to the service panel to electrically connect with the backplane of the reduced-depth rack server in response to the tray structure being inserted.
