Abstract

The invention discloses a control system and a control method for input and output flow. The control method comprises the following steps: receiving an IO resource request; calculating waiting time of the IO resource request according to a set resource index; controlling the corresponding IO resource request to perform submitting processing according to the calculated waiting time. According to the control method disclosed by the invention, virtual machine memory IO is prevented from robbing the stored resources, so that the effective flow control on the distributed type storage system is flexibly realized.

Description

technical field [0001] The present application relates to a control technology of input and output streams, and more particularly relates to a control system and method for input and output streams in a cloud computing environment. Background technique [0002] With the rapid development of hardware technology, the processing capacity of a single server is getting higher and higher. Users can use virtualization technology to deploy multiple virtual machines (VMs) on one server to achieve server resource integration and improve software and hardware utilization. , thereby saving IT costs and improving efficiency. [0003] In this cloud computing environment, a cluster or a physical server is a large resource pool, and CPU, memory, input and output (IO), and network resources have their upper limits. For storage IO resources, IO performance also has its upper limit. A single physical machine (NC) can only provide IO capabilities corresponding to its cost. However, under the c...
