The present disclosure provides a chassis and an electronic device applying the chassis. The chassis includes: a chassis body; the chassis body is a 2U chassis body or a 4U chassis body; a hard disk module, installed in a front end area of the chassis body; a power supply module, installed at one side of a rear end area of the chassis body; a controller module, installed in a remaining rear end area of the chassis body except the power supply module, parallel with the power supply module, and including a plurality of pluggable functional modules; a middle board, connected with the power supply module, the hard disk module, and the control module, respectively, to realize the electrical connection between the power supply module, the hard disk module, and the control module. The present disclosure can improve the versatility of the chassis modules.

Techniques arrange a disk, a storage device, and a disk array. Such techniques involve: a bracket configured to be detachably coupled to a rack; and a button arranged in the bracket and configured to be movable under the action of an external force to decouple the bracket from the rack, wherein a first end of the button is configured to be operated by a user, and the end surface of the first end includes a first surface and a second surface, the second surface extending from the first surface towards a second end, opposite to the first end, of the button. Accordingly, such techniques not only can avoid accidental touch, improve heat dissipation efficiency, and provide a mark area, but also can help prevent loss of user data in a storage device and a disk array.
