Abstract

Server racks may include an enclosure with an airflow inlet in a first lateral sidewall and an airflow outlet in a second, opposite lateral sidewall. A support structure may be rotatably mounted to the enclosure and rotatable between an open position and a closed position. Various other apparatuses, systems, and methods are also disclosed.

Claims (28)

1 . A server rack, comprising:

an enclosure having a depth from a front to a back of the enclosure and a width between a first lateral sidewall and a second, opposite lateral sidewall of the enclosure, wherein the depth of the enclosure is less than the width of the enclosure, the enclosure including an airflow inlet in the first lateral sidewall and an airflow outlet in the second lateral sidewall for flowing air from the first lateral sidewall to the second lateral sidewall;

a support structure rotatably mounted to the enclosure and rotatable between an open position and a closed position, wherein the support structure is rotatably mounted to the enclosure via a hinge positioned proximate an intersection between the first lateral sidewall and the front of the enclosure; and

at least one chassis mount on the support structure oriented to vertically mount multiple server chassis to the support structure such that each of the server chassis is parallel to the width of the enclosure when the support structure is in the closed position, and the multiple server chassis rotate at least partially outside of the enclosure when the support structure is in the open position for access to the multiple server chassis.

2 . The server rack of claim 1 , wherein the depth of the enclosure is less than 450 mm.

3 . The server rack of claim 2 , wherein the depth of the enclosure is in the range of about 300 mm to about 400 mm.

4 . The server rack of claim 1 , wherein the hinge has a vertical rotational axis.

5 . The server rack of claim 1 , wherein an angle between the support structure in the closed position and the support structure in the open position is at least 90 degrees.

6 . The server rack of claim 5 , wherein the angle between the support structure in the closed position and the support structure in the open position is at least 135 degrees.

7 . The server rack of claim 1 , wherein the at least one chassis mount comprises an upper chassis mount and a lower chassis mount for respectively securing a first side of the server chassis to the upper chassis mount and an opposite, second side of the server chassis to the lower chassis mount.

8 . The server rack of claim 1 , wherein, when the support structure is rotated to the open position, the server chassis are accessible to replace a field-replaceable unit of the server chassis from a back of the server chassis without removing the server chassis from the support structure.

9 . The server rack of claim 1 , further comprising a cable bundle including cables positioned to remain operably connected to the respective server chassis when the support structure is in the closed position and in the open position for access to the server chassis when the support structure is in the open position without disconnecting the cables.

10 . The server rack of claim 9 , wherein the cables of the cable bundle comprise power cables for supplying power to the server chassis.

11 . The server rack of claim 9 , wherein the cables of the cable bundle comprise data transfer cables.

12 . A mounting system for server chassis in a server rack, the mounting system comprising:

a support structure including at least one chassis mount oriented to vertically mount multiple server chassis to the support structure; and

a hinge for rotatably mounting the support structure to a server rack, the hinge having a vertical rotational axis and being configured to rotate the support structure from a closed position within the server rack to an open position at least partially outside of the server rack, wherein the multiple server chassis are parallel to a lateral width of the server rack when the support structure is in the closed position, wherein:

the support structure has a lateral width that fits within the server rack in the closed position from a first lateral sidewall to a second, opposite lateral sidewall of the server rack and has a depth from a front to a back of the server rack, wherein the depth is less than the width, and

the hinge is positioned proximate an intersection between the first lateral sidewall and the front of the server rack.

13 . The mounting system of claim 12 , wherein the hinge comprises an upper hinge element and a lower hinge element configured for rotatably mounting, respectively, an upper portion and a lower portion of the support structure to the server rack.

14 . The mounting system of claim 12 , wherein the at least one chassis mount comprises an upper chassis mount and a lower chassis mount for respectively securing a first side of the server chassis to the upper chassis mount and an opposite, second side of the server chassis to the lower chassis mount.

15 . The mounting system of claim 12 , wherein the at least one chassis mount comprises a perforated beam.

16 . The mounting system of claim 12 , wherein the hinge is configured to rotate the support structure across an angle of at least 90 degrees from the closed position to the open position.

17 . The mounting system of claim 12 , wherein the hinge is configured to rotate the support structure across an angle of at least 135 degrees from the closed position to the open position.

18 . The mounting system of claim 12 , wherein the support structure is sized to support at least three server chassis adjacent to each other.

19 . A method comprising:

rotatably coupling a support structure to a server rack such that the support structure is rotatable about a vertical axis from a closed position within the server rack having a depth from a front to a back of the server rack and a width from a first lateral sidewall to a second, opposite lateral sidewall, to an open position at least partially outside the server rack, wherein the support structure is rotatably coupled to the enclosure via a hinge positioned proximate an intersection between the first lateral sidewall and a front of the server rack, wherein the depth is less than the width; and

mounting multiple server chassis vertically to the support structure in a position such that the multiple server chassis are parallel with a lateral width of the server rack when the support structure is in the closed position and the multiple server chassis are accessible when the support structure is in the open position.
