Abstract: A method of upgrading an application in a software-defined data center (SDDC) includes: deploying, by lifecycle management software executing in the SDDC, a second appliance, a first appliance executing services of the application at a first version, the second appliance having services of the application at a second version, the services in the first appliance being active and the services in the second appliance being inactive; expanding, by the lifecycle management software, state of the first appliance to support both the services at the first version and the services at the second version; replicating, by the lifecycle management software, the state of the first appliance to the second appliance; performing, by the lifecycle management software, a switchover to stop the services of the first appliance and start the services of the second appliance; and contracting, by the lifecycle management software, state of the second appliance to remove a portion unused by the services at the second version.

Abstract: A method of upgrading an application executing in a software-defined data center (SDDC) includes: expanding a database of a first version of the application, while services of the first version of the application are active, to generate an expanded database, the expanded database supporting both the services of the first version of the application and services of a second version of the application; replicating the database of the first version to a database of the second version of the application while the services of the second version are inactive; and contracting, in response to activation of the services of the second version and deactivation of the services of the first version, the database of the second version, while the services of the second version re active, to generate a contracted database, the contracted database supporting the services of the second version.

Abstract: The present invention pertains to a method for electrolytic reduction of feedstock elements, made from feedstock, in a melt. In addition, the present invention relates to an apparatus for electrolytic reduction of feedstock elements, made from feedstock, and can be used for the reduction of oxides of metals belonging to Groups 3-14 of the Periodic Table. The method is implemented using the apparatus that, according to the invention, comprises an electrolyzer bath; an electrolytic cell; an electrolyzer bath insert plate; a cover with evolved gas outlets. Moreover, the electrolytic cell contains at least one cathode chamber and two anode plates, which are vertically arranged relative to each other, at least one current source, independently connected to the cathode chamber and one or two anode plates, and a device for horizontal reciprocating movement of the said electrolytic cell, which is found outside of the electrolyzer cover.

Abstract: The invention relates to powder metallurgy, in particular to a method for metallothermal reduction of feedstock elements made from feedstock being a solid solution of oxides of various elements in titanium oxide, using magnesium and/or calcium as reducing agents. Processes include hydrolysis of an aqueous solution of a titanium-containing salt to obtain primary particles of crystalline titanium oxide, calcination of a precipitate of titanium oxides/hydroxides, formation of feedstock elements from a milled powder of a solid solution of dopants in titanium oxide, reduction of feedstock elements in one step using calcium metal or reduction of feedstock elements in two steps, using magnesium metal or calcium metal in the first step, and calcium metal in the second step. The aim of the invention is to produce alloy powders of titanium metal with a particularly low oxygen content.
