Method for active data storage management to optimize use of an electronic memory. The method includes providing signal injections for data storage. The signal injections can include various types of data and sizes of data files. Response signals corresponding with the signal injections are received, and a utility of those signals is measured. Based upon the utility of the response signals, parameters relating to storage of the data is modified to optimize use of long-term high latency passive data storage and short-term low latency active data storage.

A computer-implemented method, a computer program product, and a computer system for data flow management in a heterogeneous memory device. A media controller redirects traffic from first non-volatile memory (NVM) to second NVM, in response to an instantaneous temperature of the first NVM reaches a first predetermined temperature at which redirecting the traffic is started. The media controller throttles to reduce the traffic to the second NVM, in response to determining that the instantaneous temperature is higher than a second predetermined temperature at which throttling is started. The media controller redirects the traffic back to the first NVM, in response to determining that the instantaneous temperature is not higher than the second predetermined temperature and lower than a third predetermined temperature at which throttling is ended. The first NVM is thermally sensitive, while the second NVM is thermally tolerant.

A data management apparatus, a data management method, and a data storage device are provided. The data management apparatus includes a management unit and a data migration unit. The management unit manages data transmission channels between two types of storage media with different transmission performance. Then, the data migration unit migrates data between the two types of storage media through the managed data transmission channels. In this way, the data management apparatus can directly migrate data between storage media with different transmission performance, and a CPU in a system does not need to perform processing such as instruction conversion and protocol conversion, so that a delay of performing the foregoing processing by the CPU can be shortened. In addition, because the CPU does not need to perform data migration, resource overheads of the CPU can be reduced.

One example method includes receiving a group of files, two or more of the files being of different respective file types, creating a backup saveset that includes the group of files, classifying each of the files in the backup saveset based in part on the respective file types of the files, assigning a respective storage media type to each of the classified files in the backup saveset, and transmitting the backup saveset to a storage site.
