Embodiments of the present disclosure provide a rack-mounted server. The rack-mounted server comprises a first drive bay and a second drive bay, the first drive bay and the second drive bay include a plurality of drive slots respectively, and the second drive bay is disposed outside of the first drive bay and rotatable about the first drive bay. By adding a rotatable drive bay, embodiments of the present disclosure enable the rack-mounted server to accommodate more disks than the traditional server, thereby effectively increasing capacity and density of disks in the rack-mounted server.

A component carrier may include a carrier front wall and a plurality of carrier side walls extending in a substantially parallel orientation to each other from opposite edges of the chassis front wall, and defining a component channel between them. The carrier side walls may include respective guide flanges extending substantially perpendicularly therefrom such that the guide flanges are in a substantially parallel orientation to each other and the guide flanges are oriented relative to the remainder of the component carrier such that when a component is mounted within the component channel to the component carrier, and the guide flanges may define a plane whereby a combined mass on a first side of the plane of the component carrier and the component is approximately equal to a combined mass on a second side of the component carrier and the component.

A chassis in a device housing includes a housing of the housing, a hard disk drive, and a fastening apparatus. The housing includes a backplane and a side plate defining an opening. The hard disk drive defining an opening is electrically coupled to the backplane. The fastening apparatus includes a connecting member and a fastening member. The connecting member includes a connecting post. The connecting post defines a mounting hole. Two locking protrusions protrude from the connecting post. A raised portion protrudes from an inside wall of the mounting hole. The fastening member includes an urging portion. The fastening apparatus is coupled between the hard disk drive and the side plate. The fastening member is mounted in the mounting hole, and the raised portion is urged by the urging portions. The connecting post undergoes elastic deformation, and the locking protrusions are locked in the openings.

A hard drive tray device applied in a server is provided. The server includes a housing. The hard drive tray device includes a rail member and a tray. The rail member is disposed at the inner wall of the housing. The tray is slidably engaged with the rail member so as to slide between an expanded position and a closed position relative to the housing. The tray includes a base for carrying two storage devices. The base has a hollow portion. The storage devices are respectively located at two sides of the hollow portion. When the tray slides to the expanded position, one of the storage devices and at least a part of the hollow portion are located outside the housing.

Cable management systems, devices, and associated methods of installation and operation are disclosed herein. In one embodiment, an enclosure for holding computer components includes a front panel, a back panel, and a side panel between the front panel and the back panel. The side panel has a first side facing an interior space of the enclosure and a second side facing away from the first side. The enclosure also includes a guide panel proximate to the side panel, the guide panel being spaced apart from the second side of the side panel by a gap extending at least partially between the front panel and the back panel. The enclosure also includes a cable anchor located in the gap between the side panel and the guide panel.

A server can be used for a cold storage application. The server can comprise a nest for holding a high density of bare storage drives, wherein the nest comprises a plurality of drive cooling channels residing on the underside of the nest. The server can further comprise rear, front, and side air flow paths for natural convection cooling.

A system includes a rack and one or more server systems mounted in the rack. A server system includes a chassis with one or more arrays of devices in the chassis. Each array includes mass storage devices and a server device mounted in the array within the chassis of the server system. The server device occupies no more than an equivalent volume of space in the chassis as one of the mass storage devices. A set of mass storage devices of an array and the server device of the array form a logical node, and a server system may include multiple logical nodes in the same chassis. Each array of devices may be located in a sled that can move into and out of the chassis of the server system.

A fixing structure for a hard disk is provided, which includes a main body, a rotation member, and at least one latching post. The main body includes two first sidewalls and a second sidewall connecting therebetween. The main body defines a groove for receiving the hard disk. At least one first sidewall defines a limiting slot. The rotation member includes two rotation arms, at least one rotation arm defines a latching slot. The rotation arms are rotatably connected to the two first sidewalls, to cause the fixing structure to be capable of switching between a first state and a second state. Each latching post is movably disposed in one limiting slot and one latching slot. When the fixing structure is switched between the first direction and the second state, the main body can move along a first direction or a second direction.

A mount bracket is adapted to fix a storage device to a first side plate. The mount bracket includes a base part and a handle. The base part includes a first support portion and a second support portion. The first support portion is configured to be removably disposed on the first side plate. The first support portion has at least one first buffering structure configured to be in contact with the first side plate. The second support portion is connected to the first support portion and configured to support the storage device. The handle is pivotably disposed on the base part.

When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.
