Title:
The data-transfer-control method of a virtual machine system and a virtual machine system
Document Type and Number:
Japanese Patent JP6072084
Kind Code:
B2
Abstract:
A computer has an adapter which is coupled to storage devices; the adapter transmits data and receives data, and measures the transfer amount of data that has been transmitted and received, and the number of I/O accesses, for each virtual computer; a virtualization part, on the basis of the transfer amount of the data, and the number of I/O accesses, acquired from the adapter, computes an upper limit for the data transfer amount and an upper limit for the number of I/O accesses for each virtual computer and reports to the virtual computers; and the virtual computers retain the data to transfer to and to receive from the storage devices in a queue, and the virtual computers control data to output from the queue so as not to exceed the upper limit of the data transfer amount or the number of I/O accesses.
