Title:
SERVICE QUALITY ASSURANCE METHOD IN DISTRIBUTED STORAGE SYSTEM, CONTROL NODE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/034819
Kind Code:
A1
Abstract:
The embodiments of the present invention disclose a service quality assurance method in a distributed storage system, a control node and a system for reducing network communication overhead. The control node calculates the lower limit number of I/O requests of a target storage node for processing storage resources within unit time according to the remaining number of I/O requests of the target storage node within unit time, the required number of I/O requests reaching the lower limit assurance of the storage resources within unit time and the number of I/O requests of the storage resources, required to be processed by the target storage node within unit time; the lower limit number of I/O requests processed by the target storage node for the storage resources within unit time are lower limit token number allocated to the target storage node by the storage resources within unit time; and the lower limit token number is sent to the target storage node. The target storage node acquires a first I/O request of a first storage resource in the I/O request queue; if the lower limit token number of the first storage resource in the target storage node is greater than 0, the first I/O request is processed.
