Abstract:
A variety of data storage devices, methods and systems are implemented for control of memory associated with backup functionality. One such data storage device includes a power circuit that provides main power. The data storage device has a first solid-state memory circuit that maintains data in the absence of electrical power. A second memory circuit is subject to data loss in the absence of electrical power. A storage circuit stores energy and provides the stored energy to the second memory circuit in response to a loss of main power. A test circuit discharges a portion of the stored energy to provide output data indicative of power-providing capabilities of the storage circuit. A memory controller controls data transfers to the data storage device by temporarily storing data destined for the first solid-state memory circuit and setting the amount of memory available for temporary storage in response to the output data.

Abstract:
A system for peer-to-peer vibration mitigation in a distributing computing system includes a secondary communication interface over which chassis management electronics (e.g., a chassis-level controller) and/or system storage nodes may initiate communications to in order to affect system changes that may decrease vibration-related performance degradation in the system.
Abstract:
A data storage system and associated method of using may generally have at least a data storage device that has independent first and second interfaces respectively connecting the data storage device to a host controller and an auxiliary controller. The auxiliary controller can be configured to provide system information to the data storage device prior to a synchronized connection being established between the data storage device and the host controller.
Abstract:
Systems and methods are disclosed for distributed power delivery. In certain embodiments, an apparatus may comprise a device configured to control power to one or more power-consuming components via managing power usage among the one or more power-consuming components based on a priority of a task associated with the one or more power-consuming components. In certain embodiments, a device may comprise a processor configured to: receive a request to allow a component to expend an amount of power, determine if the request can be satisfied with an unallocated power budget managed by the processor, the unallocated power budget being an unallocated portion of a total power budget managed by the first processor, and allow the component to expend the amount of power when the request can be satisfied with the unallocated power budget.
