20140114933 | MIGRATING DEDUPLICATED DATA - Methods and apparatuses for efficiently migrating deduplicated data are provided. In one example, a data management system includes a data storage volume, a memory including machine executable instructions, and a computer processor. The data storage volume includes data objects and free storage space. The computer processor executes the instructions to perform deduplication of the data objects and determine migration efficiency metrics for groups of the data objects. Determining the migration efficiency metrics includes determining, for each group, a relationship between the free storage space that will result if the group is migrated from the volume and the resources required to migrate the group from the volume. | 04-24-2014 |

20150088837 | RESPONDING TO SERVICE LEVEL OBJECTIVES DURING DEDUPLICATION - Technology is described for responding to service level objectives during deduplication. In various embodiments, the technology receives a service level objective (SLO); receives data to be stored at the data storage system; computes an amount of deduplication to apply to the received data responsive to the SLO; deduplicates the data to the computed amount; and stores the deduplicated data. The deduplicated data may be stored in such a manner that the data can be read in a manner that meets the SLO. | 03-26-2015 |

20100090532 | Frequency Responsive Charge Sustaining Control of Electricity Storage Systems for Ancillary Services on an Electrical Power Grid - Systems, apparatus, and methods are provided for maintaining the state of charge of energy storage devices such as batteries, flywheel, capacitors, or other technologies that are energetically coupled with the electricity grid to support ancillary services. To reliably respond to requests to regulate the grid, the charge on the energy storage device is sustained or restored to a specified range in a manner that optimizes the readiness of the energy storage device to supply ancillary services in light of the condition of the grid. A state of charge (SOC) of the energy storage device and the grid frequency may be monitored. When a request from the operator to regulate the grid frequency is not being serviced, the charge of the energy storage device may be increased or decreased so that the charge may be sustained within the specific range. Once the SOC falls outside of the first range, charge may be added to or removed from the energy storage device when the grid frequency has appropriate values, e.g. if the grid frequency is respectively above a first setpoint or below a second setpoint. | 04-15-2010 |
