Abstract:
1. A method for location resolution, comprising: receiving, from a client, a data access request directed to a local data container serviced by a first federation member of a distributed storage system; identifying an indirection construct in the local data container that references a next data container serviced by a second federation member of the distributed storage system, the indirection construct comprising a context identifier that identifies a volume location database (VLDB) comprising a location of the next data container; resolving, by the first federation member, the context identifier of the indirection construct to a network address using a name service to identify the VLDB; sending a lookup request to the VLDB after the context identifier is resolved to identify the location of the next data container; and responding to the data access request of the client with the location of the next data container.
