Abstract: Top-of-rack (TOR) switches are connected to a network fabric of a data center. Each TOR switch corresponds to a rack of the data center, and is configured to provide access to the network fabric for computing devices mounted in the rack. In one method, a client device of a user is used to select various network service options. The service options correspond to services that can be provided to computing equipment of the user that is mounted in various racks of the data center. In response to receiving the selection of one or more service options, the network fabric of the data center is configured to connect the computing equipment to the selected services. In one approach, the network fabric is configured by creating and/or configuring one or more virtual networks to provide the connection to the services.

Abstract: Cement compositions may contain a cement component and an oil-immiscible solvent and used in a number of cementing applications. In another aspect, methods for sealing subterranean zones may include emplacing a cement composition into a wellbore containing a cement component and an oil-immiscible solvent, contacting the cement composition with a water source, and reacting the cement composition with the water source to form a hardened cement.

Abstract: A method of removing a water-based filter cake from a wellbore, the method comprising: contacting the filter cake with a mixture comprising: a non-aqueous, polar solvent; an agent selected to breakdown the filter cake; said mixture comprising <5 wt % water and preferably being essentially anhydrous. The low water content of the mixture actually slows the degradation of the filter cake which has surprisingly been found to be more effective as it allows a more even removal of the filter cake and a more efficient use of the mixture; without the tendency to create local holes in the filter cake where the mixture could escape. Embodiments of the present invention use a polar solvent with a dielectric constant of more than (15), preferably more than (30) such as (15) monoethylene glycol (MEG). In preferred embodiments the agent comprises a salt based on potassium EDTA (ethylenediaminetetraacetic acid).

Abstract: Methods for reducing loss of wellbore fluid to formation may include pumping an oil-based wellbore fluid into the wellbore, where the wellbore includes an oleaginous continuous phase and a plurality of modified brine phases dispersed in the oleaginous continuous phase.
