Someone from netapp has replied to the Google and CMU drive reliability studies: http://storagemojo.com/?p=388 Confirming what we suspected about SATA/SCSI/FC being the same internally with the primary difference being the firmware. What I find most interesting about NetApp's comments are how they rail against RAID5. They say use only RAID1 or RAID6. This is in line with CMU's suggestion that the odds of a double failure in a RAID5 is greater than we think. I'm going to have to look into using Linux's RAID6 support. Hopefully it is production ready. With drives so cheap and throughput being such an issue going to more smaller/cheaper drives seems like a better idea all the time. - -- Tracy R Reed Read my blog at http://ultraviolet.org Key fingerprint = D4A8 4860 535C ABF8 BA97 25A6 F4F2 1829 9615 02AD Non-GPG signed mail gets read only if I can find it among the spam. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFF46hK9PIYKZYVAq0RAt0FAJ48ILpsmqjnaEkLWyPoN7mzsLXcmQCff1an jm0Uo2USUQulrlgcTxTOQEk= =lkR6 -----END PGP SIGNATURE----- -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
