Abstract

The invention discloses a method for scheduling read IO based on hyper-converged storage. The method for scheduling IO based on hyper-converged storage includes the following steps: when a virtual machine is running on a node of a local copy, obtain local copy limit index parameters; Determine the upper limit value of the IO pressure value on the local copy according to the limit index parameter; judge in real time whether the current IO pressure value of the local copy is greater than the upper limit value; if so, send the read request of the virtual machine to a different place copy; if not, send the read request of the virtual machine to the local copy. The invention also discloses a read IO scheduling device based on hyper-converged storage. The invention improves the performance of reading IO.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for scheduling read IOs based on hyper-converged storage. Background technique [0002] Currently, in a hyper-converged environment, each node is both a storage node and a computing node. When a virtual machine runs in a hyper-converged environment, its read IO performance is affected by the physical location of the copy. The existing read IO scheduling algorithm mainly uses read IO localization, that is, automatically identifies the local copy, and then fixes the read IO operation on this local copy. This solution makes full use of the advantages of localization, but when the IO reaches a certain pressure, the hardware on the local copy will reach a performance bottleneck. The performance of reading IO is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for scheduling rea...
