Abstract: A memory access profiling and region migration technique makes allocation and replacement decisions for periodic migration of most frequently accessed regions of main memory to least frequently accessed regions of a region migration cache, in background operations. The technique improves performance in sparsely-used memory systems by migrating regions of main memory corresponding to the working footprint of main memory to the region migration cache. A method includes profiling a stream of memory accesses to generate an access frequency ranked list of address ranges of main memory and corresponding access frequencies based on memory addresses in the stream of memory accesses. The method includes periodically migrating to a region migration cache contents of a region of main memory selected based on the access frequency ranked list. The method includes storing a memory address range corresponding to the contents of the region migration cache in a tag map.

Abstract: A storage system implements a sparse, thinly provisioned logical-to-physical translation layer. The storage system may perform operations to modify logical-to-physical mappings, including creating, removing, and/or modifying any-to-any and/or many-to-one mappings between logical identifiers and stored data (logical manipulation operations). The storage system records persistent metadata to render the logical manipulation (LM) operations persistent and crash-safe. The storage system may provide access to LM functionality through a generalized LM interface. Clients may leverage the LM interface to efficiently implement higher-level functionality and/or offload LM operations to the storage system.

Abstract: Techniques for managing restriping of data across drives of a data storage system in a mapped-RAID environment. In response to addition of a drive to existing drives of the data storage system, all drive extents of the data storage system are mapped out in an effort to consume as much free space as possible across the drives. Having mapped out the drive extents, how many free extents remain on each drive is determined. If a quantity of free extents on a drive exceeds a predetermined threshold number, then that drive is logically marked as requiring restriping. Restriping of data is then performed for all logically marked drives. Once the restriping of the data is completed, a determination is made as to whether any further restriping of data across the drives of the data storage system is required, taking into account a relative wear and/or utilization of the respective physical drives.

Abstract: A three-dimensional stacked (3DS) memory module includes multiple memory chips physically integrated with a data I/O chip. The data I/O chip includes multiple data interfaces and multiple respectively corresponding data buffers. A memory controller routes data traffic through all available data interfaces for maximum bandwidth. In some circumstances, the memory controller directs the data I/O chip to de-activate one or more of the data interfaces (for example, to reduce power consumption). All subsequent data traffic to and from the memory module is routed through the remaining active interfaces. All physical addresses in the 3DS memory module are addressable through the remaining active interfaces. In some circumstances, the memory controller directs the data I/O chip to re-activate some or all of the de-activated data interfaces. Once re-activated, subsequent data traffic to and from the memory module can again be routed through all active interfaces.

Abstract: A request is received to access physical information of a memory unit included in a memory device. A determination is made whether the physical information is available in a physical information table present in a memory cache. If the physical information of the memory unit is available in the table, the physical information is accessed from the table. If the physical information is not available in the table, a global directory in the memory cache is accessed, which indicates locations in a non-volatile memory that store the total number of the physical information blocks. From the global directory, a particular location in the non-volatile memory storing a particular physical information block that includes the physical information of the memory unit is determined. The particular physical information block is loaded into the table and the physical information of the memory unit is accessed from the particular physical information block.
