A carrierless mass storage device retainer assembly for retaining a carrierless mass storage device in a horizontal orientation comprises a base and first and second end surface receiving portions. The base defines a generally horizontal surface. The first end surface receiving portion is shaped to receive a first end of the drive and is movable between an at rest position and an engaged position. The second end surface receiving portion is shaped to receive a second end surface of the drive and has an at rest position spaced from the first end surface receiving portion. The second end surface receiving portion is movable to accommodate a length of the drive, and, with the first and second ends of the drive received therein, is movable back to the at rest position to retain the drive.

A field-replaceable unit is reversibly secured in place using two captive fasteners. Each fastener includes a telescoping knob that rotates 180 degrees in a first direction to engage a latch mechanism and rotates 180 degrees in the opposite direction to disengage the latch mechanism. The knob automatically extends when the latch mechanism is disengaged. The knob alternately extends and retracts in response to being successively pressed when the latch mechanism is engaged. The knob has two cutaways formed along outside edges to facilitate a two-finger grip for knob rotation and pulling the unit out of another module. A circular groove centered on an axis of rotation of the knob has a contrasting coloration and provides a visual and tactile indication of know location. A nub indicates rotational position of the knob.

A server casing assembly includes a casing, a first cage, a second cage, and a latch. The casing has two accommodation spaces spaced apart from each other. The first cage and the second cage are respectively accommodated in the accommodation spaces. The latch is slidably disposed on the casing. The latch is movable between a first unlocked position and a second unlocked position. When the latch is in the first unlocked position, the latch is engaged with the second cage, and the first cage is released from the latch. When the latch is in the second unlocked position, the latch is engaged with the first cage, and the second cage is released from the latch.

A chassis mounting frame includes a frame body, a fixing plate, a coupling member, a rotating member, and a pivoting member. The fixing plate is mounted on a side of the frame body and includes a resisting structure. The rotating member is provided on the frame body and coupled to the coupling member and configured to drive the coupling member to move inside the frame body and drive the coupling member and the frame body to move together. The pivoting member is provided on a side of the frame body and coupled to the coupling member. The coupling member is configured to drive the pivoting member to rotate to resist against the resisting structure.

A handle locking structure includes a handle having a pivot portion pivotally connected to a sliding box, a buckle portion for hooking on a cabinet and a handle shaft, and a positioning structure including a base connected to the handle shaft, a positioning device mounted in the base and an elastic member placed on the positioning device. When the handle is hooked on the cabinet, a peripheral limiter of a head member of the positioning device is disengaged from a position-limiting notch of the base to reset the elastic member, so that the positioning device is automatically locked to the sliding box, avoiding vibration of the handle and improving the locking stability of the handle.

A server chassis includes a casing, a first upper cover and a second upper cover. The casing includes a bottom plate and two partition plates respectively located on two opposite sides of the bottom plate so a receiving recess is formed. Each partition plate includes a first engaging groove and a second engaging groove. The first upper cover has two first engaging portions. The second upper cover has two second engaging portions. The first upper cover covers a part of the receiving recess by engaging the first engaging portion with the first engaging groove. The second upper covers another part of the receiving recess by engaging the second engaging portion with the second engaging groove. The first upper cover and the second upper cover can be detached from the first engaging grooves and the second engaging grooves in directions away from each other.

A datacenter cooling system is disclosed. The system includes a first cooling loop with a heat exchanger to exchange heat with a second cooling loop. The second cooling loop includes a cooling distribution unit (CDU) to exchange heat between the second cooling loop and a primary cooling loop.

Disclosed is a computer case with I/O panels on opposite sides of the case, and a method for providing the case. The case includes a top, a bottom, a back side that is opposite a front side, and a right side that is opposite a left side. The case also includes a front I/O opening formed in the front side that receives a front I/O panel. The computer case also includes a rear I/O opening in the back side that receives a rear I/O panel.

A modular cooling system includes a fluid pump in fluid communication with one or more cooling elements to cool electronics components; a heat exchanger in fluid communication with the fluid pump; a heat exchanger valve upstream of the heat exchanger; and a fluid supply valve positioned between a cooling fluid supply and the one or more cooling elements. When the heat exchanger valve and the fluid supply valve are in a first position, fluid is directed from the cooling fluid supply to the one or more cooling elements, bypassing the heat exchanger and the fluid pump. When the heat exchanger valve and the fluid supply valve are in a second position, fluid is cut off from the cooling fluid supply and a cooling fluid return and circulated through the heat exchanger and the fluid pump.

A cooling system configured to remove heat from a chimney of a server cabinet. The system includes a first heat exchanger unit in the chimney of the server cabinet. The first heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The first heat exchanger also has an upstream surface receiving waste heat generated by one or more servers and a downstream surface that discharges air cooled by the first heat exchanger. The upstream surface is generally perpendicular to the downstream surface.
