Abstract
A content platform cluster that comprises an array of nodes is logically partitioned. Using a web-based interface, an administrator defines 'tenants' within the cluster, wherein a tenant has a set of attributes: namespaces, administrative accounts, data access accounts, and a permission mask. A namespace is a logical partition of the cluster that serves as a collection of objects typically associated with at least one defined application. Each namespace has a private file system with respect to other namespaces. This approach enables a user to segregate cluster data into logical partitions. Tenant information, including all associated namespaces, in the cluster (the 'source cluster') is replicated to at least one target cluster over a replication link. Preferably, replication is available for multiple tenants in the source cluster, and a replication algorithm ensures that a particular tenant can be added to the replication link without stalling the progress of other tenants.
