Abstract

Disclosed is a two rack unit chassis and low profile tool-less hard disk drive carrier (HDD). The two rack chassis including a plurality of HDD bays and a backplane including a plurality of connectors corresponding to the plurality of bays, each bay configured to receive a low profile tool-less carrier. The low profile tool-less carriers each comprising a first latch configured to release a sidewall of the low profile tool-less carrier and receive an HDD, a second latch configured to release a lever having at least one protraction at an inward end, and the lever configured to couple the at least one protrusion of the low profile tool-less carrier to the connector of the corresponding bay to which the low profile tool-less carrier is inserted.

Claims

1. A low profile tool-less hard disk drive (HDD) carrier comprising:

first, second, third and fourth sidewalls, the first sidewall rotatably mounted to the second sidewall, the second sidewall being rotatably mounted to the third sidewall;

a first latch portion on the first sidewall;

a second latch portion on the fourth sidewall configured to receive the first latch portion to enclose an HDD; and

the third sidewall comprising;

a slide latch configured to release a lever having at least one protrusion at an inward end, the at least one protrusion operable to couple with an opening of a chassis, engagement of the at least one protrusion with the opening acting as a fulcrum point such that a force applied to the lever toward the third sidewall converts to a rearward force to couple a HDD connector to a connector of a backplane of the chassis.

2. The carrier of claim 1, further comprising when the slide latch is actuated the lever releases from the third sidewall of the low profile tool-less carrier by a force of a dual torsion spring.

3. The carrier or claim 1, wherein when the lever is actuated the at least one protrusion engages a cutout of the chassis and the low profile tool-less carrier is coupled to the connector by a force of a dual torsion spring and the engagement.

4. The carrier of claim 1, wherein insertion of the HDD into the low profile tool-less carrier and insertion of the low profile tool-less carrier into the bay are tool-less.

5. The carrier of claim 1, wherein the low profile tool-less carrier includes one or more light pipes along one of the sidewalls configured to display a status received from a backplane.

6. The carrier of claim 1, wherein the sidewalls are composed of a material for shielding electromagnetic interference.

7. The carrier of claim 1, wherein the sidewalls are composed of a material for absorbing vibration.

19. The carrier of claim 1, wherein the third sidewall is not rotatable relative to the fourth sidewall.

8. A two rack unit chassis comprising:

a plurality of hard disk drive (HDD) bays, each bay including an attachment portion for coupling a low profile tool-less carrier in a combination of vertical and horizontal alignments, wherein the low profile tool-less carrier comprises first, second, third and fourth sidewalls, the first sidewall rotatably mounted to the second sidewall, the second sidewall being rotatably mounted to the third sidewall;

a backplane including a plurality of connectors corresponding to the plurality of bays, each bay configured to receive a low profile tool-less carrier; and

connectors in the chassis configured to engage a lever of the carrier to serve as a fulcrum point to drive the chassis into the backplane.

9. The chassis of claim 8 wherein the bays include a subset of vertical bays and horizontal bays.

10. The chassis of claim 8 wherein the subset of vertical bays include eight bays.

11. A two rack unit chassis system with low profile tool-less carriers comprising:

a plurality of hard disk drive (HDD) bays and a backplane including a plurality of connectors corresponding to the plurality of bays, each bay configured to receive a low profile tool-less carrier, wherein the low profile tool-less carrier comprises first, second, third and fourth sidewalls, the first sidewall rotatably mounted to the second sidewall, the second sidewall being rotatably mounted to the third sidewall; and

a plurality of low profile tool-less carriers, each low profile tool-less carrier comprising;

a first latch configured to release a sidewall of the low profile tool-less carrier and receive an HDD; and

a second latch configured to release a lever having at least one protrusion at an inward end, the at least one protrusion operable to couple with an opening of a chassis of the chassis system, engagement of the at least one protrusion with the opening acting as a fulcrum point such that a force applied to the lever toward the third sidewall converts to a rearward force to couple a HDD connector to a connector of a backplane of the chassis.

12. The chassis system of claim 11, wherein the plurality of HDD bays includes eight vertical bays and twenty horizontal bays.

13. The chassis system of claim 11, further comprising when the second latch is actuated the lever releases from a front wall of the low profile tool-less carrier by a force of a dual torsion spring.

14. The chassis system of claim 11, wherein when the lever is actuated the at least one protrusion engages a cutout of the chassis and the low profile tool-less carrier is coupled to the backplane by a force of a dual torsion spring and the engagement.

15. The chassis of system claim 11, wherein insertion of the HDD into the low profile tool-less carrier and insertion of the low profile tool-less carrier into the bay are tool-less.

16. The chassis system of claim 11, wherein the low profile tool-less carrier includes one or more light pipes along a second sidewall configured to display a status received from the backplane.

17. The chassis system of claim 11, wherein the sidewalls are composed of a material for shielding electromagnetic interference.

18. The chassis system of claim 11, wherein the sidewalls are composed of a material for absorbing vibration.
