Health Reporting From Non Volatile Block Storage Device To Processing Device

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.
