  • Dynamic path partitioning to multipath storage devices
    Patent number: 7337235
    Abstract: A mechanism is provided for balancing I/O among available paths connected to a device. The mechanism partitions paths so a device can use all or only a subset of available paths to a device, depending on the load of I/O for other devices that are sharing the paths. The partitioning of paths is dynamic, readjusting as I/O loads change for the devices.
