1. A method for execution by a computing device, the method comprises: receiving a dispersed storage network (DSN) access request; determining whether the DSN access request is associated with a local DSN vault or a global DSN vault, wherein the local DSN vault is contained within a DSN of a plurality of DSNs and the global DSN vault is contained within at least some of the plurality of DSNs, wherein each of the plurality of DSNs includes a plurality of storage units, wherein the local DSN vault is a virtual memory space of at least some of the plurality of storage units of the DSN, and wherein the global DSN vault is a virtual memory space of at least some of the plurality of storage units in each of the least some of the plurality of DSNs; and when the DSN access request is associated with the global DSN vault: identifying a primary DSN of the plurality of DSNs; and facilitating processing of the DSN access request by the primary DSN, wherein the DSN access request identifies a set of encoded data slices and wherein a data segment of data is dispersed storage error encoded to produce the set of encoded data slices.
