A tree data structure for a file is maintained. The tree data structure is used to capture different versions of the file at different moments of time. An access pattern associated with the file stored on a storage system is determined based at least in part on time-series data associated with the file using the tree data structure that captures different versions of the file at different moments in time. The determined access pattern indicates a period for which the file is likely to be accessed. The file is migrated from a secondary storage tier to a primary storage tier.

Translation lookaside buffer in memory

Examples of the present disclosure provide apparatuses and methods related to a translation lookaside buffer in memory. An example method comprises receiving a command including a virtual address from a host translating the virtual address to a physical address on volatile memory of a memory device using a translation lookaside buffer (TLB).

Managing data dependencies in a transfer pipeline of a hybrid dimm

Systems and methods are disclosed including a first memory component, a second memory component having a lower access latency than the first memory component and acting as a cache for the first memory component, and a processing device operatively coupled to the first and second memory components. The processing device can perform operations including receiving a data access operation and, responsive to determining that a data structure includes an indication of an outstanding data transfer of data associated with a physical address of the data access operation, determining whether an operation to copy the data, associated with the physical address, from the first memory component to the second memory component is scheduled to be executed. The processing device can further perform operations including determining to delay a scheduling of an execution of the data access operation until the operation to copy the data is executed.

Apparatus, system, and method for managing commands of solid-state storage using bank interleave

An apparatus, system, and method are disclosed for efficiently managing commands in a solid-state storage device that includes a solid-state storage arranged in two or more banks. Each bank is separately accessible and includes two or more solid-state storage elements accessed in parallel by a storage input/output bus. The solid-state storage includes solid-state, non-volatile memory. The solid-state storage device includes a bank interleave that directs one or more commands to two or more queues, where the one or more commands are separated by command type into the queues. Each bank includes a set of queues in the bank interleave controller. Each set of queues includes a queue for each command type. The bank interleave controller coordinates among the banks execution of the commands stored in the queues, where a command of a first type executes on one bank while a command of a second type executes on a second bank.

Memory system storing management information and method of controlling same

A memory system includes a management-information restoring unit. The management-information restoring unit determines whether a short break has occurred referring to a pre-log or a post-log in a NAND memory. The management-information restoring unit determines that a short break has occurred when the pre-log or the post-log is present in the NAND memory. In that case, the management-information restoring unit determines timing of occurrence of the short break, and, after selecting a pre-log or a post-log used for restoration, performs restoration of the management information reflecting these logs on a snapshot. Thereafter, the management-information restoring unit applies recovery processing to all write-once blocks in the NAND memory, takes the snapshot again, and opens the snapshot and the logs in the past.

Embodiments of the invention provide systems and methods for managing processing, memory, storage, network, and cloud computing to significantly improve the efficiency and performance of processing nodes. Embodiments can implement an object memory fabric including object memory modules storing memory objects created natively within the object memory module and may be a managed at a memory layer. The memory module object directory may index all memory objects within the object memory module. A hierarchy of object routers communicatively coupling the object memory modules may each include a router object directory that indexes all memory objects and portions contained in object memory modules below the object router in the hierarchy. The hierarchy of object routers may behave in aggregate as a single object directory communicatively coupled to all object memory modules and to process requests based on the router object directories.

Scoped persistence barriers for non-volatile memories

A processing apparatus is provided that includes NVRAM and one or more processors configured to process a first set and a second set of instructions according to a hierarchical processing scope and process a scoped persistence barrier residing in the program after the first instruction set and before the second instruction set. The barrier includes an instruction to cause first data to persist in the NVRAM before second data persists in the NVRAM. The first data results from execution of each of the first set of instructions processed according to the one hierarchical processing scope. The second data results from execution of each of the second set of instructions processed according to the one hierarchical processing scope. The processing apparatus also includes a controller configured to cause the first data to persist in the NVRAM before the second data persists in the NVRAM based on the scoped persistence barrier.
