  • Transparent host-side caching of virtual disks located on shared storage
    Patent number: 11093402
    Abstract: Techniques for using a cache to accelerate virtual machine (VM) I/O are provided. In one embodiment, a host system can intercept an I/O request from a VM running on the host system, where the I/O request is directed to a virtual disk residing on a shared storage device. The host system can then process the I/O request by accessing a cache that resides on one or more cache devices directly attached to the host system, where the accessing of the cache is transparent to the VM.
    Type: Grant

  • Techniques for surfacing host-side storage capacity to virtual machines when performing VM suspend or snapshot operations
    Patent number: 9778847
    Abstract: Techniques for surfacing host-side flash storage capacity to a plurality of VMs running on a host system are provided. In one embodiment, the host system creates, for each VM in the plurality of VMs, a flash storage space allocation in a flash storage device that is locally attached to the host system. The host system then causes the flash storage space allocation to be readable and writable by the VM as a virtual flash memory device.

  • Transparent host-side caching of virtual disks located on shared storage
    Patent number: 9454487
    Abstract: Techniques for using a host-side cache to accelerate virtual machine (VM) I/O are provided. In one embodiment, the hypervisor of a host system can intercept an I/O request from a VM running on the host system, where the I/O request is directed to a virtual disk residing on a shared storage device. The hypervisor can then process the I/O request by accessing a host-side cache that resides one or more cache devices distinct from the shared storage device, where the accessing of the host-side cache is transparent to the VM.
