Abstract: Improved power management techniques for computer-readable storage devices are described. In one embodiment, for example, an apparatus may comprise a plurality of logical storage devices and a controller to manage operations of the plurality of logical storage devices, the controller comprising a configuration component to configure a global power consumption threshold defining an overall power consumption budget for the plurality of logical storage devices, a tracking component to maintain a global power consumption tally comprising an estimated total power consumption level for the plurality of logical storage devices, and an arbitration component to resolve an operation request based on the global power consumption threshold and the global power consumption tally. Other embodiments are described and claimed.

Abstract: Method and system are provided for handling data when power failure from a primary power source of a storage system is detected. The system provides a first memory and a second memory. The first memory is primarily used to store data when the primary power source is operating. If a power failure is detected, a first indicator is set to indicate that data is stored or being transferred to the second memory. Thereafter, data is transferred from the first memory to the second memory. Any errors during the transfer are logged. Once power is restored, data is transferred back to the first memory. A second indicator is set to indicate that there is no data at the second memory.
