Abstract: A network storage controller uses a non-volatile solid-state memory (NVSSM) subsystem as a global cache that is shared between a number of network storage servers in a network storage system. Portions of global cache are allocated to each of the network storage servers. Allocation of portions of the global cache is controlled based on a usage pattern of the global cache by each of the network storage servers. The storage operating system determines, for example, a percentage of cache hit and/or a response time for responding to the requests from the clients by a particular network storage server with a particular allocated portion. The percentage of cache hit and response time are projected for various potential sizes of the particular portion. A size of the particular portion that provides a better percentage of cache hit and/or response time is selected, and reallocated to the particular network storage server.

Abstract: Various embodiments are generally directed an apparatus and method for performing a discovery operation to determine a system layout for a database and one or more files for a dataset stored in the database and performing a backup operation on the dataset to cause storage of a backup copy of each of the one or more files and collect metadata associated with the backup copy of each of the one or more files, the metadata to enable restoration of the one or more files.
