Abstract: A system including a memory configured to store instructions, a host processor, an interface coupling the non-volatile memory and the host processor, and a device driver is provided. The device driver is configured to execute commands stored in the memory to retrieve a maximum queue size value from a hardware queue, wherein the hardware queue is associated with an interface between the host processor and a non-volatile memory, to determine multiple software queues associated with the hardware queue, to read an input/output count for a software queue selected from the software queues, to decrease the assigned queue depth, when the input/output count for the software queue is lower than an assigned queue depth, and to increase the assigned queue depth when the input/output count for the software queue is greater than the assigned queue depth.

Abstract: A system and method for identifying lost/stale peripheral hardware devices connected to an enterprise computer system is disclosed. In one embodiment, a method for identifying lost peripheral hardware devices connected to an enterprise computer system includes initializing system memory by obtaining data structures associated with last detected connected peripheral hardware devices stored in an external database upon reboot, initiating an enterprise computer system wide scanning to obtain the detected data structures associated with current connected peripheral hardware devices during the reboot, and comparing the obtained data structures associated with the last detected connected peripheral hardware devices and the current connected peripheral hardware devices to determine whether there is any chance in system resources associated with the connected peripheral hardware devices during the reboot.

Abstract: A method of managing power supply to at least one device in a data processing system, the method comprising determining when the at least one device has been associated with no resources for a predetermined period of time; turning off the power supply to the at least one device; determining that the at least one device is required for use by the data processing system; and restoring the power supply to the at least one device.

Abstract: A method and system for handling errors on an Input/Output (I/O) link of a system is provided. The link is being shared by a plurality of devices of the system; each device may be shared by one or more operating systems. The method of error handling during configure of the system includes steps of checking a device for an error during configuration of the system and restricting the device from being configured, if an error is detected. The method includes the steps of examining the device capabilities to recover from errors, and; configuring the device in a first mode if the device has capabilities to recover from errors, else configuring the device in a second mode or not configuring the device. Further the handling of error may also be performed during runtime of the system, for doing so the step of checking is followed by a step of isolating and deleting the device if value of a number indicative of errors encountered for the device is greater than a threshold value.

Abstract: A method for determining the criticality of a device in a multi-path computer configuration comprising the steps of: traversing a directed acyclic graph representing a platform hierarchy; and determining paths within the directed acyclic graph affected by the removal of the device.
