Patent ID: 8504857

Claim:
A storage system comprising: a storage array including a plurality of enclosures, the plurality of enclosures including: a first enclosure having a first link control card module and a second link control card module with electronics configured to provide redundant functionality to the first link control card module, the second link control card module of the first enclosure being a sole source of the redundant functionality for the first link control card module of the first enclosure; a second enclosure having a first storage processor module and a second storage processor module with electronics configured to provide redundant functionality to the first storage processor module, the second storage processor module of the second enclosure being a sole source of the redundant functionality for the first storage processor module of the second enclosure, the second enclosure further comprising a first power supply module and a second power supply module with electronics configured to provide redundant functionality to the first power supply module, the second power supply module of the second enclosure being a sole source of the redundant functionality for the first power supply module of the second enclosure; and a host system in communication with the storage array, the host system having a processor programmed to associate a separate power profile with each module of each enclosure in the storage array, the processor being programmed to configure each module to power down and restore power to a major portion of the electronics of each module in accordance with each separate module power profile, wherein the separate power profile associated with the second link control card module of the first enclosure powers down the second link control card module during a copy or move of data from the storage system, and wherein the separate power profiles of the first and second link control card modules of the first enclosure and of the first and second storage processor modules of the second enclosure comprise a trigger condition to individually power down the associated modules when a workload of the storage system falls below a predetermined threshold.
