Storage device and an array of disks, and an apparatus for arranging disk

A storage device, comprising:

• an apparatus which includes:
• a bracket configured to couple to and detach from 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 an end surface of the first end comprises a first surface and a second surface,
• wherein the first surface is parallel to an XY plane in a Cartesian coordinate system defined by an X-axis, a Y-axis, and a Z-axis,
• wherein the bracket has a longitudinal axis parallel to the Y-axis, and
• wherein the second surface extends in a direction of the X-axis from the first surface towards a second end, opposite to the first end, of the button;
• and
• a disk which is coupled to the bracket and extends in a direction of the Z-axis.

A disk array, comprising:

• a rack on which a plurality of storage devices including a particular storage device are arranged side by side,
• wherein the particular storage device includes
• (i) an apparatus having:
• 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 an end surface of the first end comprises a first surface and a second surface,
• wherein the first surface is parallel to an XY plane in a Cartesian coordinate system defined by an X-axis, a Y-axis, and a Z-axis,
• wherein the bracket has a longitudinal axis parallel to the Y-axis,
• wherein the second surface extends in a direction of the X-axis from the first surface towards a second end, opposite to the first end, of the button;
• and
• (ii) a disk which is coupled to the bracket,
• wherein adjacent storage devices from among the plurality of storage devices arranged side by side on the rack extend in a direction of the Z-axis, and
• wherein first surfaces and second surfaces of buttons of the adjacent storage devices are alternately arranged in the direction of the X-axis.
