Abstract: A request is received from a client device of a user for configuring a tenant of a multi-tenant storage system, the multi-tenant storage system storing data for different tenants. An entity identifier (ID) identifying an entity to be associated exclusively with the tenant is obtained from the request. A lookup operation is performed based on the entity in an SMT registry namespace cache stored in a memory to locate an entry that matches the entity. If no matching entry is found, the request is allowed. If a matching entry is found, a first tenant ID obtained from the request is compared with a second tenant ID stored in the matching entry. The request to configure the tenant is allowed if the first tenant ID matches the second tenant ID. The request is denied if the first tenant ID does not match the second tenant ID.

Abstract: The present invention relates to an extensometer for measuring high-temperature structural deformations by magnification, the structure of the extensometer is that: two mounting block assemblies are mounted at the planar ends of two extension bars respectively, the top ends of the extension bars are connected tightly with the surface of a test piece, two connecting pieces are mounted at the inner sides of the two mounting block assemblies respectively, a deformation magnifying mechanism and a sensor bracket are mounted on the connecting pieces, a sensor is mounted on the sensor bracket, two connecting pieces are mounted on a same straight line, and the straight line is parallel to a straight line at which the top ends of the two extension bars are located, so as to ensure that the deformation of the test piece is delivered equally to the deformation magnifying mechanism on the connecting pieces.
