Abstract: In some implementations, a hard drive carrier is configured to couple and decouple a hard drive to/from a chassis (e.g., motherboard). The hard drive carrier can receive and house a hard drive in a base securing portion, the base securing portion adapted to slide and tilt in relation to a base of the hard drive carrier. The hard drive carrier can include a pivoting lever comprising a handle that can be used to couple and decouple the hard drive from the motherboard. Using the handle to pivot the lever into an open position causes the hard drive to tilt upwards to decouple from the chassis and facilitate insertion or removal of the hard drive to/from the hard drive carrier. Pivoting the lever into a closed position causes the hard drive to lie flat and couple to the chassis.

Abstract: A system and method for efficient allocation of remote storage devices to computing devices in a rack is disclosed. An end of the rack switch is provided with physical storage devices and a storage service. The switch includes ports that are coupled to network interface cards of computing servers. The storage service allows each of the computing servers to access the physical storage devices. The network interface card includes a controller that can be configured into virtual storage controllers to allow access to different storage volumes.

Abstract: Various embodiments of the present technology provide systems and methods to pair each of a plurality power supply units (PSUs) of a server system with a corresponding one of a plurality of ATS modules. A failed ATS module or PSU can be detected and replaced without forcing a shutdown of the remaining pairs of PSUs and ATS modules of the server system. In some embodiments, a controller of the server system can monitor status of each of the plurality ATS modules and the plurality of PSUs. Based at least in part upon statuses of the plurality ATS modules and the plurality of PSUs, the controller may further determine an optimized output power of the PSUs and manage loading of the server system.

Abstract: A server device includes a tray having a lug, a hard disk unit removably disposed on the tray, and a handle pivotally connected to two opposite sides of the hard disk unit. The lug is formed with a slot thereon to define two inner edges opposite to each other. The handle is provided with a protrusion arranged in the slot. When the handle is rotated towards one end of the hard disk unit, the protrusion is rotated along with the handle to contact and push one of the inner edges of the lug, such that the hard disk unit is restrained by the tray after the hard disk unit is slid in relative to the tray.

Abstract: In some implementations, power provided to a computing system, such as a rack system, may be interrupted. This interruption is detected, and in response, power from a battery backup system is directed to the computing system to replace the interrupted power source, which in some implementations may be a main AC power grid source. A signal is received indicating that a backup power source, for example a backup generator system, is online and prepared to deliver power to the computing system. For an initial period of time, this backup power source is prevented from providing power to the computing system. For example, the backup generator system may be providing power to a power supply unit of the computing system, but the power is not allowed to flow to the computing system.
