20100048382 | TOLUENE SELECTIVE DISPROPORTIONATION CATALYST - The present invention discloses a catalyst for toluene shape selective disproportionation, comprising: a) 45 to 95 wt % of ZSM-5 molecular sieve having an average particle size of from 0.3 to 6 μm and a molar ratio of SiO | 02-25-2010 |
20120110287 | SNAPSHOTS IN A HYBRID STORAGE DEVICE COMPRISING A MAGNETIC DISK AND A SOLID STATE DISK - One or more snapshots of data stored over a period of time are maintained in a hybrid storage device comprising a magnetic disk and a solid state disk, wherein a selected snapshot stores information that allows recovery of data that is stored in the hybrid storage device at a selected point in time of the period of time. The hybrid storage device receives an input/output (I/O) command from a computational device. A category of a plurality of categories to which the I/O command belongs is determined, wherein the plurality of categories comprise writing to an unused block, writing to a used block, reading from an unused block, and reading from a used block. In response to determining the category to which the I/O command belongs, the I/O command is handled by one of the magnetic disk and the solid state disk based on the determined category. | 05-03-2012 |
20120278571 | MIGRATING VIRTUAL MACHINES ACROSS SITES - The invention relates to apparatus and methods for managing data swap in a migration of virtual memory data of a virtual machine. In one embodiment, an apparatus comprises a receiving unit configured to receive a migration instruction and the second site information; a copying unit configured to copy memory data to a sub-logical unit in the first storage device; and a notifying unit configured to send a notification to instruct the second host to read the memory data from a mirror logical unit of a sub-logical unit in the second storage device. The apparatus modifies a mirror direction between the first and second storage devices and modifies a path table related to the first and second storage devices. Data of the virtual machine can be migrated and swapped in a metro mirror manner, thereby the virtual machine data can be migrated across sites without affecting system operation. | 11-01-2012 |
20130086340 | MANAGING STORAGE DEVICES IN A CLOUD STORAGE ENVIRONMENT - A method of managing storage devices including storage resources that are virtualized and integrated into corresponding intermediate volumes, wherein the intermediate volumes are virtualized and integrated into individual logical volumes. The method comprises acquiring storage resource requirements presented to the logical volumes where the requirements comprise redundancy, obtaining storage resources available from respective intermediate volumes, selecting intermediate volumes to satisfy the storage resource requirements based on the requirements and available storage resources, where a minimum number of the intermediate volumes is determined based on the required redundancy, and storing user data in selected intermediate volumes based on the required redundancy. | 04-04-2013 |
20130198561 | MIGRATING VIRTUAL MACHINES ACROSS SITES - In one embodiment, a method for managing data swapping in a migration of virtual memory data in a virtual machine, wherein the data swapping is from a first storage device at a first site to a second storage device at a second site, and the first and second storage devices have a metro mirror relationship includes sending a fail report in response to a failure to access the first storage device according to a path table, in response to the fail report, modifying a mirror direction between the first and second storage devices, sending a path modifying notification for modifying settings of a first path to the second storage device, and activating the path to the second storage device by modifying the path table according to the path modifying notification, so as to make the second storage device accessible. | 08-01-2013 |
20130343880 | TURBINE END INTAKE STRUCTURE FOR TURBOCHARGER, AND TURBOCHARGER COMPRISING THE SAME - A turbine end intake structure for a turbocharger includes a turbine housing, a turbine having multiple blades and located in a turbine shell, and thermal insulation located between the turbine end of the turbocharger and another part. A flow-guiding channel for engine exhaust gases is provided on the turbine housing in communication with the interior of the turbine housing. An inner surface of the turbine housing matching peripheral edges of the blades is a cylindrical surface coaxial with the turbine, while the shape of the peripheral edges of the blades follows the cylindrical surface. Angle-cut portions are provided on the blades at positions corresponding to an intake port of the flow-guiding channel. The thermal insulation has an outwardly extending flow-guiding part, and a flow-guiding path for engine exhaust gases formed by the flow-guiding channel and the flow-guiding part is perpendicular to the angle-cut portions of the blades. | 12-26-2013 |

20150074453 | MIGRATING VIRTUAL MACHINES ACROSS SITES - A method for managing data swapping in a migration of virtual memory data in a virtual machine, where the data swapping is from a first host associated with a first storage device to a second host associated with a second storage device, is provided in another embodiment. The method includes receiving a migration instruction indicating the virtual machine to be migrated, and instructing the first host to copy data of the virtual machine to a sub-logical unit in the first storage device, the sub-logical unit having a mirror logical unit in the second storage device. A notification is sent, the notification being usable to instruct the second host to read data from the mirror logical unit. | 03-12-2015 |
