HOST DEVICE WITH ADAPTIVE LOAD BALANCING UTILIZING HIGH-PERFORMANCE DRIVERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240311025 titled 'HOST DEVICE WITH ADAPTIVE LOAD BALANCING UTILIZING HIGH-PERFORMANCE DRIVERS
Simplified Explanation: This patent application describes an apparatus with a processing device that maintains queue depth measures for different paths through which input-output operations are delivered from a host device to a storage system. The device controls path selection for delivering additional operations based on these queue depth measures.
- The processing device includes a multi-path input-output driver of the host device.
- The driver is a lockless polled-mode driver implemented in the user space of the host device.
Key Features and Innovation:
- Apparatus with a processing device maintaining queue depth measures for paths of input-output operations.
- Control of path selection based on queue depth measures.
- Inclusion of a multi-path input-output driver in the host device.
- Implementation of a lockless polled-mode driver in the user space of the host device.
Potential Applications: This technology can be applied in various storage systems and host devices to optimize input-output operations and improve performance.
Problems Solved: This technology addresses the challenge of efficiently managing input-output operations between host devices and storage systems.
Benefits:
- Enhanced performance of input-output operations.
- Improved efficiency in data transfer between host devices and storage systems.
Commercial Applications: Optimizing data transfer and input-output operations in storage systems can benefit industries such as cloud computing, data centers, and network storage solutions.
Prior Art: Readers can explore prior art related to input-output operations management in storage systems and host devices to understand the evolution of this technology.
Frequently Updated Research: Stay informed about the latest advancements in input-output operation optimization and storage system performance to leverage cutting-edge solutions in this field.
Questions about Input-Output Operation Optimization: 1. How does this technology improve the efficiency of data transfer between host devices and storage systems? 2. What are the key features of the multi-path input-output driver in the host device?
Original Abstract Submitted
an apparatus illustratively comprises at least one processing device that comprises a processor coupled to a memory. the at least one processing device is configured to maintain in a host device queue depth measures for respective paths over which input-output operations are delivered from the host device to a storage system, and to control path selection for delivery of additional input-output operations from the host device to the storage system based at least in part on the queue depth measures maintained for the paths. the at least one processing device may comprise at least one multi-path input-output driver of the host device, with maintaining the queue depth measures and controlling the path selection being performed at least in part by the at least one multi-path input-output driver of the host device. the multi-path input-output driver illustratively comprises a lockless polled-mode driver implemented in a user space of the host device.
