  • Dynamic balancing of IO resources on NUMA platforms
    Patent number: 8725912
    Abstract: A method for binding input/output (I/O) objects to nodes. The method includes receiving, by an I/O Subsystem, a request to use an I/O device from a process, determining a first resource to service the request, and generating a first I/O object corresponding to the first resource. The method includes sending the first I/O object to a NUMA I/O Framework, obtaining a first I/O object effective load from the first I/O object, and obtaining a first I/O load capacity of a first NUMA node of a plurality of NUMA nodes. The method includes comparing the first I/O load capacity and the first I/O object effective load, selecting the first NUMA node based on a determination that the first I/O load capacity is greater than the first I/O object effective load, binding the first I/O object to the first NUMA node, and processing the first resource corresponding to the first I/O object.

  • Dynamic intent log
    Patent number: 7606812
    Abstract: A method for dynamic intent logging in a file system. The method including pre-allocating a first log block, receiving a request to write a first set of deltas into a dynamic intent log, determining whether a size of the first set of deltas is larger than a size of the first log block, if the size of the first set of deltas is not larger than the size of the first log block, storing the first set of deltas in the first log block and pre-allocating a second log block.
