Abstract
Embodiments of the present application relate to a method for scheduling virtual disk input and output (I/O) ports, a device for scheduling virtual disk I/O ports, and a computer program product for scheduling virtual disk I/O ports. A method for scheduling virtual disk I/O ports is provided. The method includes assigning a set of service quality ratings to a corresponding set of virtual disk I/O ports based on a set of reading-writing bandwidth quotas associated with the corresponding set of virtual disk I/O ports in a physical machine, determining a total forecast value of a data bandwidth to be used by reading-writing requests and determining virtual disk I/O ports, allocating reading-writing bandwidth limits to the virtual disk I/O ports, and scheduling virtual disk I/O ports on the physical machine.
