what is your understanding of "Pirmary/Primary"?

  do you want to use a cluster file system on top of that?

  or do you want to have each site active for *its set* of shares,
  and be the backup only for the respective other site's set?

what does "geographically remote" mean in link latency and bandwidth?

 30 km FO dedicated 1Gbps low latency feeling for all practical purposes
 almost like a lan?

 3000 km 1Mbps flaky high latency bell wire?

what is "a file repository"?
  what kind of files?
  why would you need synchronous replication,
  why would rsync not do?

what is your expected storage size?

what is your estimated average write rate?

what is you estimated peek write rate?
