Abstract: Power systems and methods for supplying direct current power to a server rack via a power shelf assembly that includes multiple power supply units (PSUs) and a power shelf controller (PSC) that ensures a correct configuration of PSUs, backup battery units (BBUs), and connection components using a power shelf configuration record. Upon a boot cycle of the PSC, the configuration identified in the power shelf controller is compared to an actual configuration of the components being connected between a server rack and the power shelf assembly to avoid providing power too soon and causing an overload of components for the server rack.

Abstract: Techniques for securely destroying data stored on a portable storage device may be provided. For example, a portable storage device includes a first memory configured to store data while a current is supplied by a second device or a capacitor of the first device. One or more capacitors of the portable device may be configured to store a charge to provide the current to the first memory. A processor that is configured to access computer-executable instructions of a second memory of the first device may provide instructions to enable transfer of the data stored in the first memory to the second device. In particular embodiments, the data stored in the first memory may be erased in response to the current no longer being provided by the second device or the one or more capacitors.
