Your comment on needing to "store *a lot* of data (like 50TB max)" is very relative. For sites like ours and many others, *a lot* of data means 100's of PB. :)
As to your questions RE: GlusterFS, this announcement has also recently made the rounds on the beowulf mailing list though there has not been too much conversation about it. Being new, nobody has tried it as of yet, as such there are not many comparative studies (if any) out there. What they claim to be able to do is quite nice. But then again, many vendors and other FOSS cluster file systems have made such claims in the past. Only time will tell. The only real thing I can offer is that I will be watching this very closely which might lend some credence to Gluster as a potential solution.
