Abstract: Systems for controlling cycling operations for backup battery units in a datacenter include groups of backup battery units and power supply units that can supply power to datacenter components from either a primary power supply or, the backup battery units. Each group of multiple battery units has sufficient capacity to provide backup power to a respective electronic device even when one battery unit is offline. In operation, a controller receives requests to perform cycling operations, e.g. maintenance, on the backup batteries. Upon each request, the system retrieves status information corresponding to each backup battery unit and determines whether the remainder of the backup battery units can supply sufficient power to meet or exceed power demand, and either allow or prevent each backup battery unit from performing the cycling operation in response to determining whether the remainder of the backup battery units can or cannot supply sufficient power.

Abstract: Disclosed herein are techniques for maintaining a secure execution environment on a server. In one embodiment, the server includes a non-volatile memory storing firmware, a programmable security logic coupled to the non-volatile memory, an adapter device coupled to the programmable security logic, and a processor communicatively coupled to the non-volatile memory via the programmable security logic. The adapter device and/or the programmable security logic can verify the firmware in the non-volatile memory while holding the processor and/or a baseboard management controller (BMC) in power reset, release the processor and the BMC from reset to boot the processor and the BMC after the firmware is verified, and then disable communications between the processor and the BMC and deny at least some requests to write to the non-volatile memory by the processor or the BMC.

Abstract: A rack-mountable computer system enables an airflow that cools components in an upstream portion of the computer system interior to be cooled through mixing with a bypass airflow downstream of the components in the upstream portion. The mixed airflow can cool components in a downstream portion of the interior. The bypass airflow is directed by a bypass plenum that is unencompassed by the separate plenum that directs the airflow to cool the upstream portion components. The bypass plenum can be at least partially established by an external surface the computer system and one or more external structures, including an external surface of an adjacently mounted computer system. Relative flow rates through the separate plenums can be adjusted, via flow control elements, to separately control heat removal from components upstream and downstream of the air mixing, based at least in part upon air temperatures in the separate interior portions.

Abstract: A system includes a rack and one or more server systems mounted in the rack. A server system includes at least one sever node and each server node includes an array of devices including mass storage devices and at least one server device. Segments of the array of devices of a particular server node are mounted in sub-node chassis that include intra node connectors. Multiple sub-node chassis that each include devices such as mass storage devices or server devices of the sever node couple together via the intra node connectors when installed in a server system chassis to form a server node. Each server node of a server system may be a separate logical node. Also, the sub-node chassis of a server node may be configured for vertical airflow through the sub-node chassis in addition to cross airflow.

Abstract: Technologies are provided for using an index in one region of a storage device to track modifications to data stored in another region of the storage device. The index can be stored in a first storage region using a first storage format, and data items can be stored in a second storage region using a second storage format. The index can map logical identifiers for data items to locations in the second storage region where the data items are stored. Instead of modifying a data item in the second storage device region, an entry in the index can be updated to mark the data item as deleted. Requests for data items can be reconciled using the index before returning the requested data items. Storage locations in the second region that are associated with index entries that are marked as deleted can be reclaimed and used to store additional data items.

Abstract: A system and method are described for configuring a motherboard using expansion cards plugged into motherboard slots. In particular, each of the expansion cards can include a control signal that is supplied to the motherboard and that can configure hardware positioned on the motherboard. In one embodiment, the configuration allows a communication path to be switched on to allow the expansion cards to cross communicate.

Abstract: 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.

Abstract: A data center may include a tape library rack module along with rack computer systems. The rack computer systems may be configured to provide computing capacity within a data center environment. In some embodiments, the tape library rack module may include an enclosure encompassing an interior of the tape library rack module, a rack within the interior, and a tape library unit mounted on the rack. The tape library rack unit may include tape cartridges configured to store data within a tape environment that is different than the data center environment. The tape library rack unit may be within a portion of the interior that is enclosed such that it is environmentally isolated from the data center environment. In some examples, the tape library rack module may include a cooling unit and/or a humidifier unit, which may provide the tape environment to the environmentally isolated portion of the interior of the tape library rack module.

Abstract: A system for storing data includes a rack and one or more data storage modules mounted on the rack. The data storage modules may include a chassis, two or more vertically-oriented backplanes coupled to the chassis, two or more mass storage devices coupled to the backplanes, and one or more air passages extending beneath one or more of the backplanes. Each backplane is configured to preclude airflow through the backplane between opposite vertical faces and can couple mass storage devices on one or more of the opposite vertical faces. One or more of the air passages can supply an upwards-directed airflow along one of the opposite vertical faces of a backplane to remove heat from a heat producing component of a mass storage device coupled to the vertical face of the vertically-oriented backplane.

Abstract: A humidification assembly includes an enclosure, for example, arranged around a component of a datacenter. A base extends through a wall of the enclosure. Inside the enclosure, the base includes a well. Outside the enclosure, the base receives a container having a total volume that includes water and air. Water may flow from the container through a passage in the base to the well, for example, until equilibrium is reached and a predetermined water level in the well is thereby maintained. Water from the well thus provides a replenishing source of water to be evaporated for humidifying the air within the enclosure.
