Abstract: A mass data storage system includes a number of communicatively coupled storage drives powered and controlled by shared control electronics. The shared control electronics are configured to transmit analog read/write signals through an interconnect to each of the multiple individually selectable storage drives. The interconnect bi-directionally couples the control electronics to each of the multiple selectable storage drives.

Abstract: A modular fan assembly for use in a multi-device storage enclosure. In some embodiments, the fan assembly has a rigid open frame with opposing first and second ends. A first fan is connected to the first end and a second fan is connected to the second end. The first and second fans are configured to establish a fluidic airflow through the frame. An airflow diverter positioned in an intermediate portion of the frame between the first and second ends divert at least a portion of the fluidic airflow through a first aperture of the frame to cool an active element outside the frame.

Abstract: A carrier board for use with a host computing system includes bus connectors for one or more removable memory modules. The carrier board includes energy storage components and control circuitry to charge the energy storage components using a voltage source provided by the host computing system. If the host computing system experiences a power failure, the control circuitry initiates discharge the energy storage components to power the carrier board. As such, the memory controller on the carrier board may initiate steps to secure any data that would have been lost due to the power failure, such as data that is part of write operations in progress at the time of the power failure or data to be migrated as part of garbage collection operations.

Abstract: A data storage enclosure may house at least two data storage devices and consist of a first electrical connector and a latch feature. The first electrical connector may be aligned with a second electrical connector of a data storage rack. The latch feature can be configured to contact a frame of the data storage rack to prevent the first and second electrical connectors from contacting until a lever of the latch feature is activated.

Abstract: Apparatus for retracting and extending sets of operational processing devices in a multi-device enclosure. In accordance with some embodiments, an enclosed housing is provided with opposing first and second ends. Sleds are individually movable between a retracted position within the enclosed housing and an extended position in which the sled projects from the first end. Each sled supports a group of processing devices. A control board is disposed within the enclosed housing adjacent the second end. A plurality of flex circuits contactingly engage the processing devices to provide communication paths between the processing devices and the control board in both the retracted and extended positions of the sleds.

Abstract: Apparatus and method for maintaining processing devices at a nominally common temperature, such as but not limited to storage devices in a multi-device networked storage enclosure. In accordance with some embodiments, an enclosed housing has a first side adjacent a cold zone with a lower ambient temperature and an opposing second side adjacent a warm zone with a higher ambient temperature. First and second processing devices are arranged within the enclosed housing so that the first processing device is adjacent the cold zone and the second processing device is adjacent the warm zone. First and second thermal interface material (TIM) modules are contactingly affixed to the first and second devices and are provided with different heat conductivities so that the first and second devices are maintained at a nominally common operational temperature.
