Two rack unit chassis and low profile tool-less hard drive carrier

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.

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.
