Abstract: Methods and apparatuses are described to provide a mechanism to improve replication performance by understanding available bandwidths of multiple source servers and load balancing the replication among the source servers based on fingerprints of data units to be replicated. A separate source server can be identified for one source server to replicate the data units to a target server. A replication request is sent from the one source server to the separate source server to identify the data units. A reply may be received from the separate source server to indicate that one or more of the data units are replicated from the separate source server. Subsequently, the remaining ones of the data units not indicated in the reply may be sent directly from the one source server to the target server without sending the one or more data units indicated in the reply.

Abstract: In one embodiment, a request is received from a remote device of a user for configuring a tenant-unit of a storage system via a secure connection session. A secure multi-tenancy (SMT) module determines a first network identity associated with the secure connection session. The SMT module examines an SMT registry namespace associated with the tenant-unit of the tenant to determine a second network identity that has been assigned to the tenant-unit. The first network identity is compared with the second network identity. The request is allowed to configure the tenant-unit in response to determining that the first and second network identities match; otherwise, the request is denied.
