Abstract
A server can be used for a cold storage application. The server can include a nest for holding a high density of bare storage drives. The nest can include a plurality of drive cooling channels residing on the underside of the nest. The server can further include rear, front, and side air flow paths for natural convection cooling.
Claims21
A server for a plurality of hard drives, the server comprising:
- a chassis;
- a nest positioned within the chassis, the nest comprising a plurality of bays and a plurality of air channels, wherein:
- the plurality of bays are arranged in rows and columns and are configured to position a hard drive of a plurality of hard drives within each of the bays of the plurality of bays;
- and
- each of the plurality of air channels is in fluid communication with at least one of the plurality of bays;
- a printed circuit board configured to be physically and electrically connected to the plurality of hard drives;
- and
- a plurality of spacers configured to maintain a gap between a cover and the printed circuit board, the cover configured to secure the plurality of hard drives within the chassis, each spacer configured to contact a respective hard drive of the plurality of hard drives and the cover and configured to transfer heat from the respective hard drive to the cover.
