Embodiment Construction

[0015] Examples are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will appreciate that other components and configurations may be used without departing from the spirit and scope of the disclosed subject matter.

[0016] overview

[0017] In various embodiments consistent with this disclosed subject matter, various methods and apparatus are disclosed so that a non-volatile block storage device may provide information to storage subsystem components of an operating system executing on a processing device. This information may indicate desired changes to input / output (I / O) patterns to reduce negative impact on the non-volatile block storage device, or to enhance aspects of the non-volatile block storage device.

[0018] In a first embodiment according to this disclosed subject matter, a storage subsystem component of an operating system exec...

Abstract

Methods and devices are provided for adapting an I/O pattern, with respect to a processing device using a non-volatile block storage device based on feedback from the non-volatile block storage device. The feedback may include information indicating a status of the non-volatile block storage device. In response to receiving the feedback, a storage subsystem, included in an operating system executing on processing device, may change a behavior with respect to the non-volatile block storage device in order to avoid, or reduce, a negative impact to the non-volatile block storage device or to enhance an aspect of the non-volatile block storage device. The feedback may include performance information and/or operating environmental information of the non-volatile block storage device. When the non-volatile block storage device is not capable of providing the feedback, the processing device may request information about the non-volatile block storage device from a database service.

Description

Background technique [0001] Non-volatile memory devices are sensitive to input / output patterns. For example, in a flash memory device, excessive repetitive writing to a given memory block will eventually damage the ability of the given memory block to store data. Some existing non-volatile block storage devices employ wear leveling to spread erasures over a series of logical block addresses (LBAs) to avoid or reduce negative shocks to the non-volatile block storage device. However, existing non-volatile block storage devices typically do not provide feedback to the processing device regarding the ongoing health of the flash memory cells and the input / output mode employed by the processing device. [0002] Currently, a storage controller of a processing device submits input / output streams according to an input / output schema designed into the storage subsystem components of an operating system executing on the processing device. The storage subsystem component may adjust certa...
