Last-generation server hardware supports ECC, and was usually populated with ECC. Last-generation desktop hardware rarely supports ECC, and was even more rarely populated with ECC. The thing is, last-generation server hardware is, um, marvelously adequate for most home setups (the problem *I* see with it, for many home setups, is that it's *noisy*). So, if you can get it cheap in a sound-level that fits your needs, that's not at all a bad choice. I'm running a box I bought new as a home server, but it's NOW at least last-generation hardware (2006), and it's still running fine; in particular the CPU load remains trivial compared to what the box supports (not doing compression or dedup on the main data pool, though I do compress the backup pools on external USB disks). (It does have ECC; even before some of the cases leading to that recommendation were explained on that list, I just didn't see the percentage in not protecting the memory.) -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
