X-Mailer: exmh version 2.7.2 01/07/2005 with nmh-1.3 Greetings, Has anyone out there built a 1-petabyte pool? I've been asked to look into this, and was told "low performance" is fine, workload is likely to be write-once, read-occasionally, archive storage of gene sequencing data. Probably a single 10Gbit NIC for connectivity is sufficient. We've had decent success with the 45-slot, 4U SuperMicro SAS disk chassis, using 4TB "nearline SAS" drives, giving over 100TB usable space (raidz3). Back-of-the-envelope might suggest stacking up eight to ten of those, depending if you want a "raw marketing petabyte", or a proper "power-of-two usable petabyte". I get a little nervous at the thought of hooking all that up to a single server, and am a little vague on how much RAM would be advisable, other than "as much as will fit" (:-). Then again, I've been waiting for something like pNFS/NFSv4.1 to be usable for gluing together multiple NFS servers into a single global namespace, without any sign of that happening anytime soon. So, has anyone done this? Or come close to it? Thoughts, even if you haven't done it yourself?
