A device to detect hot-plugging and hot-unplugging of hard disk and the hard disk type includes a connector and a control circuit. When hot-plugged, the hard disk is coupled to the connector, the control circuit comprises delay circuit and latch circuit. The delay circuit delays a falling edge of the third signal and outputs a delay signal, the latch circuit processes the first and second signals and outputs a logical result as a latch signal. The control circuit determines the connected or disconnected status and type of the hard disk according to the respective levels of the first and second signals, the delay signal, and the latch signal. The delay signal and the latch signal work to correct error of the control circuit in determining connectivity and non-connectivity during a session due to asynchronous changes in signal levels of the first and second signals.

A hard disk fixing device according to an embodiment of the present disclosure includes a hard disk box, a baffle and a snap. A first end of the baffle is rotatably installed on a first side edge of the hard disk box, a first end of the snap is rotatably installed on a second side edge of the hard disk box, and a second end of the snap is engaged with a second end of the baffle. As such, the hard disk box, the snap and the baffle form an accommodating cavity to limit a hard disk, and the accommodating cavity can accommodate the hard disk.

A device carrier for an information handling system includes a latch, an interface, lights located on a front of the latch, and first and second light pipes. The latch holds the device carrier within the information handling system. The first light pipes are located within the latch, and provide light to the lights located on the front of the latch. The second light pipes are located within the interface and the latch, and provide the light to the first light pipes. The location of the second light pipes enables the same brightness of the light provided to the lights when a long device is inserted within the device carrier as compared to when a short device is inserted within the device carrier.

A drive carrier for retaining a persistent storage drive in an enclosure. The drive carrier includes a mounting bracket, a handle coupled to the mounting bracket, and an electromagnetic interference (“EMI”) shielding apparatus disposed between mounting bracket and at least a portion of the handle. The mounting bracket is shaped to be coupled to the persistent storage drive. The EMI-shielding apparatus includes a plurality of EMI-shielding fingers. Each EMI-shielding finger includes a lower surface, an upper surface that is approximately parallel to the lower surface, and a contoured surface extending between the lower surface and the upper surface.

A system for storing data includes a discrete cooling module that can enable discrete cooling of mass storage devices installed in the chassis interior of a data storage module coupled to a rack. The discrete cooling module includes an air moving device and an air cover. The air moving device can induce and airflow through the chassis interior of the data storage module to remove heat from heat producing components of mass storage devices installed in the chassis interior. The air cover directs the airflow through the chassis interior. The discrete cooling module can isolate rotational vibrations generated by the air moving device from the mass storage devices installed in the chassis. Partial isolation can include indirectly coupling the discrete cooling module to the chassis via directly coupling with the rack.

An electronic device includes a case module, a circuit board, a detachable module and a lever mechanism. The detachable module is detachably installed on the case module and slidable relative to the case module, and an electrical connector of the detachable module is mated with a mating electrical connector of the circuit board when the detachable module is installed on the case module and slides to an engaging position. The lever mechanism includes a lever component partially located between the case module and the detachable module, and an abutting component fixed on the case module. When the lever component is operated to pivot relative to the detachable module, the lever component cooperates with the abutting component in a contacting manner to drive the detachable module to slide, so as to disengage the electrical connector of the detachable module from the mating electrical connector of the circuit board.

A drive carrier for a device of an information handling system includes first and second portions. The first and second portions are placed in physical communication with the device. The first portion includes first and second side rails to secure the device within the drive carrier. The first and second side rails slide within a first slot of a bay of the information handling system. The second portion is located on top of the first portion and floats away from and toward the first portion when the drive carrier is inserted with the bay of the information handling system. An amount of float for the second portion is based on a bay pitch of the bay.

A server chassis includes at least one first tray, at least one second tray, a housing, a first interface, the housing includes a bottom wall and a side wall, the bottom wall and the side wall surrounds and forms a receiving cavity with an opening. The first interface is located in the receiving cavity; the first interface is placed at a corner of the bottom wall close to the opening and the side wall. The first tray and the second tray are stacked in the receiving cavity, and the first tray is located below the second tray. The first tray slides out or retracts the receiving cavity through the opening. The second tray slides out or retracts the receiving cavity through the opening; the first tray and the second tray are configured to carry hard disks of a plurality of arrays. The present disclosure also provides a server.

This disclosure relates to a server including a storage chassis, a tray, a hard disk, a bracket, and a fan. The storage chassis includes a bottom plate and two sidewalls. The sidewalls respectively stand at two opposite sides of the bottom plate The bottom plate has a front edge and a rear edge that are opposite to each other and located between the sidewalls. The tray is slidably disposed on the storage chassis. The hard disk is disposed on the tray. The bracket is connected to the rear edge of the storage chassis. At least part of the bracket is located at a side of the rear edge of the storage chassis away from the front edge. The fan is disposed in the bracket, and the fan is electrically connected to the hard disk.

A retention assembly includes a first retention member with a first set of ribs and a second set of ribs. The first set of ribs are positioned to form slots, which are shaped to receive data storage devices. The first set of ribs are arranged to separate adjacent data storage devices and have a first length. The second set of ribs extend into respective slots to form air channels within the slots, and the second set of ribs have a second length that is shorter than the first length.
