By the way, does anyone have any real performance comparison with Lustre? While it is good to have another solution available, I don't see any real benefits of FhgFS/BeeGFS compared to Lustre these days. At the time where FhgFS was created, Lustre indeed was unable to use multiple metadata servers, so this was a bottleneck. But now Lustre also supports distributed metadata, so they should on par in this matter. On the other hand, Lustre has much larger community (e.g. see TOP-500 list) and is much better tested (and even under such conditions it has problems in some corner cases). Thus I see no advantage in FhgFS for HPC setups. Of course world of parallel distributed file systems is very versatile, so for different tasks/workloads different file systems are the most suitable, but for typical IB-based HPC storage I see no better solution than Lustre at this moment.
