Title:
ストレージシステムにおける電力割当てのための方法及び装置
Document Type and Number:
Japanese Patent JP5727582
Kind Code:
B2
Abstract:
Methods and systems for improved management of power allocation among a plurality of devices coupled to a controller. The controller (102) and devices (106.1 .. 106.4) exchange messages to request, grant, and release allocations of power from a common power supply (108). In some embodiments, the controller may be a SAS/SATA controller and the messages exchanged may be SAS/SATA frames and/or primitives. In exemplary embodiments, the messages may request/grant a particular amount of power for each of one or more voltage levels provided by the power supply. In other exemplary embodiments, the messages may designate the duration of time during which the requesting device may utilize the allocated power. A power status message from the device to the controller may indicate a change in the power consumption by the device. Responsive to the power status message the controller may re-allocate power previously allocated to a device that has completed use thereof.
