The BDB-based repository back end can handle multiple server processes
on the same machine. However, BDB relies on locking through shared
memory segments, which does not work over distributed filesystems.

The FSFS repository back end can handle multiple server processes on
different machines, each accessing the repository through a distributed
filesystem. It requires only the basic ability to lock files; no need
to lock byte ranges. (I'm not sure that DFS works well enough to be an
option, but AFS or sufficiently modern NFS are fine.)
