No 32 bit > issues there.... Nice setup Dave. I've thought about converting my vanity server to an Atom 330 64 bit dual core microATX board. Haven't got around to it yet. A little over $100 USD sent to Newegg and a bit of time is all it would take. With summer fast approaching I may just take the plunge to lower the heat generation in the home office. My current old dual proc Intel server expels about 80-100 watts aggregate continuous at idle. With the Atom that should drop to well less than 30 (even more if I splurge for a new more efficient PSU). Something maybe worthy of note: only 5 of the 19 Atom processors are 64 bit. The remaining 14 are 32 bit only. Hope the link doesn't get horribly mangled. If it does just go to the Atom product page, click the select all button and then compare. That'll get you the same chart I'm looking at. http://ark.intel.com/Compare.aspx?ids=46467,35635,35641,43517,43098,36331,41411,42503,35472,35469,41175,41176,40740,35466,41174,35463,41173,35460,40741, I don't know how many of each Atom model have been sold, but I think it's safe to assume there are a lot of the 32 bit only Atom CPUs in the wild. I'll concede that probably not many such systems are running XFS, probably just a few geeks like us. Then again, I don't know the retail DVR market at all, or if any units use the 32 bit Atom chips. I would think XFS would be a natural choice for DVR duty though. Anyway, this may be a total non issue, but I just wanted to point out that there are definitely some corner cases of 32 bit Atom with big XFS filesystems in DIY DVRs/HTPCs, as well as maybe some other applications. I'll still be 32 bit for a while on the vanity server, but my XFS filesystems are all less than 250GB, so I'm assuming I should be safe from inodes over 32 bits. -- Stan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
