| 发明名称 | Virtual volume converter | ||
| 摘要 | In one aspect, a method includes providing virtual volumes (VVols) and mappings from the VVols to corresponding data storage devices to an I/O filter in a first virtual machine (VM), sending control path commands sent from the first VM to a control-path manager VM, the first VM and the control-path manager VM being run on a VM host, intercepting an I/O for a VVol using the I/O filter and sending the intercepted I/O to a data storage device mapped to the VVol. | ||

| 主权项 | 1. A method comprising: providing, using a control-path manager virtual machine (VM) comprising virtual volume (VVol) targets, virtual volumes (VVols) and mappings from the VVols to corresponding data storage devices to an I/O filter in a first virtual machine (VM); sending control path commands sent from the first VM to one or more of the virtual volume targets by bypassing the I/O filter, the first VM and the control-path manager VM being run on a VM host; intercepting an I/O for a VVol using the I/O filter; and sending the intercepted I/O to a data storage device mapped to the VVol. | ||
