I tried running one datanode per machine connecting back to the same SAN but it seemed pretty clunky. A crash of any datanode would take down the entire system (no data replication since it's a common data-store in the end). Reducing it to a single datanode did not have this impact.
Why use NDFS at all? Why not just mount the SAN on all hosts? You're not using NDFS as a distributed file system, but rather as a centralized file system.
