Data storage system with parallel array of dense memory cards and high airflow

A rack-mountable enclosure comprising:

• a plurality of parallel solid-state drive (SSD) cards, proximate a front of the enclosure, having a ruler form factor, the plurality of parallel SSD cards extending from a position proximate the front of the enclosure toward a rear of the enclosure;
• a switch fabric between the plurality of parallel SSD cards and the rear of the enclosure and connected to the plurality of parallel SSD cards;
• a power supply to power the plurality of parallel SSD cards and the switch fabric;
• a platform management controller, wherein, each of the power supply and the platform management controller is between the plurality of parallel SSD cards and the rear of the enclosure, and
• an array of rear fans, between the power supply and the rear of the enclosure to pull air from the plurality of parallel SSD cards out the rear of the enclosure.

A solid-state drive (SSD) array chassis, comprising;

• an enclosure configured to mount in a rack, the enclosure having a front configured to receive airflow and a rear configured for an external cabling interface;
• a rigid horizontal plane printed circuit board (PCB) having a plurality of parallel slotted SSD card connectors, each of the plurality of parallel slotted SSD connectors having respective latches on ends of each slotted SSD connector, and a plurality of external interfaces, the rigid horizontal plane PCB having a first side and a second opposite side, and wherein the horizontal plane PCB is mounted between a first level and a second level of the enclosure;
• a plurality of SSD cards, respectively coupled to the plurality of SSD card connectors, each of the plurality of SSD cards at the first level within the enclosure and having a ruler form factor;
• a power supply at the first level within the enclosure, proximate the rear of the enclosure, and the first side of the rigid horizontal plane PCB to provide power to the plurality of SSD cards through the plurality of SSD card connectors, comprising a rear fan to pull air from the front of the enclosure between the plurality of SSD cards and to push air out the rear of the enclosure;
• and
• a switch fabric coupled to the plurality of SSD cards and a computing device coupled to the switch fabric, wherein the switch fabric and the computing device are at the second level within the enclosure.
