MULTI-PATH LAYER CONFIGURED WITH ENHANCED AWARENESS OF LINK PERFORMANCE ISSUE RESOLUTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240103724 titled 'MULTI-PATH LAYER CONFIGURED WITH ENHANCED AWARENESS OF LINK PERFORMANCE ISSUE RESOLUTION

Simplified Explanation

The patent application describes a system where a processing device controls the delivery of input-output operations from a host device to a storage system over selected paths through a network. The processing device can designate certain paths as having link performance issues, suspend the utilization of those paths, detect configuration changes indicating potential issue resolution, and resume utilization of the paths accordingly.

  • This technology involves a processing device that manages the delivery of input-output operations in a network environment.
  • The system can identify and address link performance issues by temporarily suspending the use of designated paths.
  • Configuration changes indicating potential issue resolution trigger the resumption of utilizing the designated paths for IO operations.

Potential Applications

This technology can be applied in:

  • Data centers
  • Cloud computing environments
  • Storage systems

Problems Solved

  • Efficient management of IO operations in a network
  • Addressing link performance issues in real-time

Benefits

  • Improved performance and reliability of IO operations
  • Enhanced network efficiency and resource utilization

Potential Commercial Applications

Optimizing IO operations in:

  • Enterprise storage solutions
  • Networking hardware
  • Cloud service providers

Possible Prior Art

One possible prior art could be the use of multi-path input-output (MPIO) drivers in storage systems to enhance data transfer speeds and reliability.

Unanswered Questions

How does the system prioritize paths for IO operations in case of multiple link performance issues?

The patent application does not specify how the system handles multiple link performance issues and prioritizes paths for IO operations.

What mechanisms are in place to prevent data loss during the suspension and resumption of IO operations on designated paths?

The patent application does not detail the safeguards in place to ensure data integrity during the suspension and resumption of IO operations.


Original Abstract Submitted

at least one processing device is configured to control delivery of input-output (to) operations from a host device to a storage system over selected ones of a plurality of paths through a network. the at least one processing device is further configured to designate one or more of the paths as being associated with a link performance issue, to temporarily suspend utilization of the one or more designated paths for delivery of io operations from the host device to the storage system, to detect a configuration change that is indicative of potential resolution of the link performance issue, and to resume utilization of the one or more designated paths responsive to the detected configuration change. the at least one processing device illustratively comprises a multi-path input-output (mpio) driver of the host device.
