The first backplane includes a first backplane network switch that connects to the top-of-rack and connects to each of the first plurality of chassis via the chassis network switch of each of the first plurality of chassis.

Abstract in the disclosure a retaining device (1) for stopping a relative movement between a rail member and a sliding rack (3) is provided, includes: a first member (11), having a first engagement portion; a second member (12), having a second engagement portion; and a handle member (13) pivotally mounted onto the first member (11) via a pivot (14). The second member (12) includes a stopping portion (121), and the handle member (13) includes a first contacting edge (131) and a second contacting edge (132) which are configured to selectively abut against the stopping portion by means of the pivotal movement of the handle member (13). A distance between the second contacting edge (132) and the pivot (14) is greater than a distance between the first contacting edge (131) and the pivot (14), such that a distance between the first and the second engagement portions when the second contacting edge (132) contacts the stopping portion (121) is greater than a distance between the first and the second engagement portions when the first contacting edge (131) contacts the stopping portion (121).

A data storage system with a parallel array of dense memory cards and high airflow is described. In one example, a rack-mount enclosure has a horizontal plane board with memory connectors and external interfaces. Memory cards each have a connector to connect to a respective memory connector of the horizontal plane board, each memory card extending parallel to each other memory card from the front of the enclosure and extending orthogonally from the first side of the horizontal plane board. A power supply proximate the rear of the enclosure and the first side of the horizontal plane board provides power to the memory cards through the memory card connectors and has a fan to pull air from the front of the enclosure between the memory cards and to push air out the rear of the enclosure.
