BlobSeer-WAN was initially designed as an extension of BlobSeer, targeting geographically distributed environments. With BlobSeer-WAN, the metadata is replicated asynchronously for low latency. There is a version manager on each site and vector clocks are used to allow collision detection and resolution under highly concurrent access. Several experiments have been conducted with this setup on the Grid'5000 testbed which have shown scalable metadata performance under geographically distributed environments. Currently, BlobSeer-WAN is integrated within BlobSeer, as a new release of the latter.

BlobSeer-WAN has been preliminarily evaluated at University of Tsukuba (Japan) in the context of the FP3C project. BlobSeer-WAN is used as a storage backend for HGMDS, a multi master metadata server designed for a global distributed file system.
