Abstract
Methods and apparatus facilitate the management of input/output (I/O) subsystems in virtual I/O servers to provide appropriate quality of services (QoS). A hierarchical QoS scheme based on partitioning of network interfaces and I/O subsystems transaction types are used to classify Virtual I/O communications. This multi-tier QoS method allows virtual I/O servers to be scalable and provide appropriate QoS granularity.
