Abstract: A memory controller specifies, from a nonvolatile memory, a final page candidate, which is a candidate to be the physical page to which data is last written in a logical block. The memory controller executes an upward check process to determine whether the number of programmed physical pages is among a first range number of physical pages in a reverse order from the final page candidate is equal to or greater than a first reference value. The memory controller executes a downward check process determining whether the number of programmed physical pages is among a second range number of physical pages existing in the downward order from the final page candidate is equal to or less than a second reference value, and specifies the physical page to which data is last written in the logical block from results of the upward check process and the downward check process.

Abstract: A controller of a non-volatile, dual, in-line memory modules (NVDIMM). A NVDIMM is configured to predict thermal events associated with save and restore operations prior to starting the save or restore operation. The controller of the NVDIMM includes a thermal event prediction circuit to predict whether a thermal event will occur in response to a request to perform a save or restore operation, and to cause the controller to perform an action in response to a determination that a thermal event is likely to occur. To predict the thermal event, the controller may be configured to predict a peak temperature of the save or restore operation based on a predicted temperature increase from an initial or starting temperature. The predicted temperature increase may be based on a rate of temperature change during the save or restore operation and a duration of the save or restore operation.

Abstract: Storage managers are used in data storage management systems for license distribution, compliance, and updates. A licensed quota is managed at an aggregate level applicable to a collective plurality of storage operation cells and not by licensing each individual storage operation cell. A multi-cell environment belonging to a given customer is licensed by using an enhanced storage manager in each cell. One storage manager is a “license server” to the other storage managers or “child licensees.” A licensor issues a global license to the customer's designated license server, which distributes child licenses and manages other licensing aspects. Rather than licensing usage for individual storage operation cells, licensed usage is managed at an aggregate level using the license server and child licensees in a “self-service” model.
