System and method for ensuring per tenant mutual exclusion of data and administrative entities with low latency and high scale

摘要

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.
