Title:
METHOD AND DEVICE FOR DETECTING SLOW DISK
Document Type and Number:
WIPO Patent Application WO/2017/054690
Kind Code:
A1
Abstract:
A method and a device for detecting a slow disk, relating to the technical field of computers, and being capable of solving the problem of low accuracy of slow disk detection. The method comprises: acquiring average service time, in a current pre-set period, for input/output (I/O) requests corresponding to disks of different types (101); acquiring, according to the relationship between the average service time for the I/O requests corresponding to the disks of different types and pre-set values, slow disk thresholds corresponding to the disks of different types in a next preset period (102); determining, according to the slow disk thresholds corresponding to disks of different types and the average service time for the I/O requests corresponding to each of the disks in the next pre-set period, a slow disk in the next pre-set period (103). The present solution is used for dynamically adjusting the slow disk thresholds.
