A method and system for managing print shop workflow determines whether variations in print shop workflow may be reduced by shifting one or more customers' scheduled orders to different time periods. By shifting an order from one time period to another, the system may reduce variability in demand levels over time, thus helping increase overall system efficiency. To do this, one or more customers are selected as candidates for print shop order rescheduling. The system identifies customer orders that, if moved to other time periods, will most reduce demand level variations. A user may accept the system's recommendations, or the system may present a user with several alternative load leveling options for selection. The system may then cause the orders to be printed based on the load leveling proposal and the user's selection.

Certain example embodiments relate to memory management techniques that enable users to “pin” elements to particular storage tiers (e.g., RAM, SSD, HDD, tape, or the like). Once pinned, elements are not moved from tier-to-tier during application execution. A memory manager, working with at least one processor, receives requests to store and retrieve data during application execution. Each request is handled using a non-transitory computer readable storage medium (rather than a transitory computer readable storage medium), if the associated data is part of a data cache that is pinned to the non-transitory computer readable storage medium, or if the associated data itself is pinned to the non-transitory computer readable storage medium. If neither condition applies, the memory manager determines which one of the non-transitory and the transitory computer readable storage mediums should be used in handling the respective received request, and handles the request accordingly.

In a cache policy for a hybrid drive having a magnetic storage device and a non-volatile solid-state device, the hybrid drive is configured to write the most recent version of data associated with a logical block address to the non-volatile solid-state device when the logical block address is associated with previously written data and is overlapped by a subsequent disk write operation. Advantageously, the most recent version of data associated with the overlapped logical block address is stored in cache in the non-volatile solid-state device, even when the subsequent disk write operation results in the overlapped logical block address being trimmed from cache or otherwise invalidated. Consequently, data associated with the overlapped logical block address can be accessed more quickly than data written to the magnetic storage device.

SYSTEMS AND METHODS FOR BALANCING MULTIPLE PARTITIONS OF NON-VOLATILE MEMORY

Номер: US20220147258A1

Автор: Paley Alexander, Vogan Andrew W.

Принадлежит:

Systems and methods for balancing multiple partitions of non-volatile memory devices are provided. Embodiments discussed herein execute a balance proportion scheme in connection with a NVM that is partitioned to have multiple partition types. Each partition type has an associated endurance that defines an average number of program/erase (P/E) cycles it can endure before it reaches failure. For example, a first partition type may have a substantially greater endurance than a second partition type. The balance proportion scheme ensures that, even though each partition type has a different associated endurance, all partition types are used proportionally with respect to each other to balance their respective P/E cycles. This way, both partition types will reach the upper limits of their respective endurance levels out at approximately the same time. 1. A method implemented in a computing device having a non-volatile memory comprising a first partition and a second partition each having different program/erase endurances , the method comprising , at the computing device:accessing parameters associated with each of the first partition and the second partition;evaluating the parameters to determine whether the first partition or the second partition is overheating, wherein overheating indicates that one of the first partition and second partition has a higher proportional usage than the other partition;in response to determining that the first partition is overheating, implementing a first balancing scheme that balances a proportional usage of the first partition relative to the second partition to prevent the first partition from prematurely reaching an end of life parameter;in response to determining that the second partition is overheating, implementing a second balancing scheme that balances a proportional usage of the second partition relative to the first partition to prevent the second partition from prematurely reaching the end of life parameter; andexecuting ...
