Method for optimizing system performance by dynamically tracking IO processing path of storage system

Abstract

The invention provides a method for optimizing system performance by dynamically tracking an IO processing path of a storage system, which comprises the following steps: sending a read and write request to the storage system through a network by using a server; tracking an IO request in each device; introducing an IO request inspection mechanism into the process of processing the request by the storage system; setting an IO processing identification for each process module; computing the response time of each processing node; computing the total processing time of the whole IO request throughthe formula and recording in a blog mode; accurately positioning the error through the time of processing the IO request and improving, wherein the time for processing the IO request is displayed in the blog; fully developing the system capacity through changing system resources distributed to each user and service programs; and meeting the requirements of the users by using possibly less resources and achieving the purpose of serving various users.

Description

technical field [0001] The invention relates to the field of IO path tracking of a computer storage system, in particular to a technology suitable for tracking IO processing of a network storage system and confirming that the system bottleneck has reached optimized system performance by analyzing the IO response time. [0002] technical background [0003] With the rapid development of network applications, the storage system often handles a large number of IO requests at the same time. Whether it uses synchronous or asynchronous processing methods, due to the limitations of hardware resources and software performance, there will be a lot of IO requests in the process of system processing. In the waiting for response stage for a long time, a large number of IO requests that are not processed in time will cause system processing to be blocked, thereby forming a system performance bottleneck. [0004] For the development of the storage system, performance testing is an extreme...

Problems solved by technology

[0002]With the rapid development of network applications, storage systems often process a large number of IO requests at the same time. Due to performance limitations, the system will spend a long time waiting for a response during the process of processing IO requests. A large number of IO requests that are not processed in time will cause system processing to block, thereby forming a system performance bottleneck.
