Publication number: 20120191929Abstract: Exemplary embodiments provide rapid creation and deployment of virtual machines by reducing communication processes between virtual machine user and storage and server administrators. One embodiment is a method for deploying virtual machines of host computers. A storage subsystem provides a pool of pre-created virtual volumes in the storage subsystem prior to deploying the virtual machines, the pre-created virtual volumes having pre-copied images for the virtual machines. The method comprises: selecting one of the pre-created virtual volumes for deploying one of the virtual machines; calculating a volume size for the selected virtual volume based on a specified image size for data and OS image; resizing the selected virtual volume according to the calculated volume size; and requesting one of the host computers to deploy the virtual machine using the resized virtual volume.Type: ApplicationFiled: January 21, 2011Publication date: July 26, 2012Applicant: HITACHI, LTD.Inventors: William ZIETZKE, Yoshiki KANO, Dan RITCHIE, Fumimasa NAKANE, Hiromichi OTA

Patent number: 7938602Abstract: In a three degrees of freedom parallel mechanism, a spindle head is carried by first and second movable support members to be movable along a Z-axis and to be pivotable along each of A and B-axes. The spindle head is jointed through three rods to drive sliders which are movable along three parallel linear guides secured stationarily. For jointing, there are employed spherical joints and universal joints. Kinematic parameters used in converting each command position of the movable body to target operational positions for three actuators of the Z, A and B-axes are compensated based on inversely converted command positions and inversely converted actually measured positions which have been gathered with the spindle head being located at positions of a suitable number, so that the kinematic parameters can be updated to those newest.Type: GrantFiled: March 19, 2007Date of Patent: May 10, 2011Assignee: JTEKT CorporationInventor: Hiromichi Ota
