Cloud-native global file system with direct-to-cloud migration
A cloud-native global file system used to provide primary file storage for enterprise data is augmented to provide “direct-to-cloud” (D2C) migration of an initial data set. In addition to providing a filer, the service provider configures a direct-to-cloud migration tool, typically as a downloadable virtual machine (VM), that is executed in association with the hardware of the enterprise filesystem whose data set is being migrated. The migration tool reads the existing filesystem, transforms the data into a format consistent with that done by a filer, and pushes the result (a single version) directly to an object store in the cloud. In a first pass (run), typically a large bulk of the data is moved and, depending on how the migration tool is configured, one or more additional passes may then be carried out. When migration is complete (or substantially complete), the filer then is activated to complete the migration (if need be) and take over the go-forward operations. |

Double coupon reference cell and methods of making same
A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface thereof is disclosed. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket is formed from a blank having a first surface and an opposing second. A pocket as a recess is machined into the first surface, a groove is machined into the opposing second surface and an aperture is machined through the bottom of the pocket and opens into the groove. A disc-shaped coupon assembly was threaded through the pocket and aperture to seat the disc-shaped coupon in the pocket and a wire in the groove with the electrical junction therebetween aligned with the aperture. |

Method and device for homogeneously coating 3D substrates
A method and a device are provided for homogeneously coating surfaces of 3D substrates in a vacuum chamber which has a sputtering source, such as a planar source or a tube or double-tube source, wherein individual substrates, with a curved substrate surface directed toward the sputtering source, are able to be moved past said source in a translational manner. The sputtering source is fastened to a chamber wall within a vacuum chamber so as to have two degrees of freedom such that the sputtering source is able to be set both in terms of its spacing to a surface to be coated of a substrate, which is moved past in front of said sputtering source in a translational manner, and with respect to the surface normal of the surface to be coated proceeding from a fixed point such that the surface normal deviation is 0° at all times. |
