  • Hypervisor controlled redundancy for I/O paths using virtualized I/O adapters
    Patent number: 10387180
    Abstract: A method, system, and program product for hypervisor controlled redundancy for Input/Output (I/O) paths using virtualized I/O adapters is provided. A hypervisor detects a virtual machine exceeding a pre-defined bandwidth threshold. The hypervisor searches a shared pool of free virtual functions (VF) for a free VF. If the shared pool of free VFs is not depleted, a free VF is allocated to the virtual machine (VM). If the shared pool of free VFs is depleted, the active VMs are examined for VF capacity that may be donated to the triggering VM.

  • Implementing dynamic adjustment of I/O bandwidth for virtual machines using a single root I/O virtualization (SRIOV) adapter
    Patent number: 9569244
    Abstract: A method, system and computer program product are provided for implementing dynamic adjustment of Input/Output bandwidth for Virtual Machines of a Single Root Input/Output Virtualization (SRIOV) adapter. The SRIOV adapter includes a plurality of virtual functions (VFs). Each individual virtual function (VF) is enabled to be explicitly assigned to a Virtual Machine (VM); and each of a plurality of VF teams is created with one or more VFs and is assigned to a VM. Each VF team is enabled to be dynamically resizable for dynamic adjustment of Input/Output bandwidth.
