Abstract: Disclosed herein are system, method, and computer program product embodiments for of big block allocation of persistent main memory. An embodiment operates by receiving an allocation request for memory of a requested size. A free memory block, that exceeds the requested size by a remainder and is available for allocation, is determined. A size of the free memory block is updated to indicate that the size of the free memory block is equal to the remainder size. A new block of the requested size is inserted with an indication that the new block is allocated. A memory address corresponding to the new block is returned.

Abstract: A storage area setting unit sets (2M+L) storage areas (M>L≥1 and L is an integer) in a storage device, for storing M pieces of data from M data sources (M≥2 and M is an integer). A data specifying unit specifies an L piece of data as write-target data, from among the M pieces of data from the M data sources. A write-destination specifying unit specifies within the (2M+L) storage areas, a storage area that is a write destination of the L piece of write-target data, from among storage areas excluding storage areas from which data is read during the L piece of write-target data is being written, storage areas into which data from each data source has been written last, and storage areas from which data from each data source has been read last. A write processing unit writes the L piece of write-target data into the specified storage area.

Abstract: Digital objects are stored and accessed within a fixed content storage cluster by using a page mapping table and a pages index. A stream is read from the cluster by using a portion of its unique identifier as a key into the page mapping table. The page mapping table indicates a node holding a pages index indicating where the stream is stored. A stream is written by storing the stream on any suitable node and then updating a pages index stored within the cluster responsible for knowing the location of digital objects having unique identifiers that fall within a particular address range. The cluster recovers from a node failure by first replicating streams from the failed node and reallocating a page mapping table to create a new pages index. The remaining nodes send records of the unique identifiers corresponding to objects they hold to the new pages index.

Abstract: A method for managing memory operations in a storage device having a plurality of data blocks, the method including steps for determining a number of page reads for each of the plurality of data blocks and determining a dwell time for each of the plurality of data blocks. In certain aspects, the method further includes steps for associating the plurality of data blocks with a plurality of rank groups based on the number of page reads and the dwell time associated with each of the plurality of data blocks and selecting a data block, from among the plurality of data blocks, for memory reclamation based on the associated rank group and the selected data block. A storage system and computer-readable media are also provided.

Abstract: Techniques are disclosed which allow a secondary storage system to provide data to non-production workloads in conjunction with performing data backup and protection tasks. As disclosed, a secondary storage system exposes backup data stored by the secondary storage system to other workloads, such as test and development applications, data analytics, etc. These non-production workloads can run at the same time the secondary storage system provides backup services to a primary storage system. This consolidation eliminates the need for an enterprise to deploy separate storage clusters for analytics, test and development applications, etc. and eliminates unnecessary copies of data.
