Be careful when talking about RAID controllers in general. They are not created equal! I can remove all of my disks from my RAID controller, reshuffle them and put them back in a new random order.. my controller will continue functioning correctly. I can remove my RAID controller and replace with a similar firmware (or higher), and my volumes will continue to live with correct initiators blacklisted/not. Hardware raid controllers have done the job for many years ... I'm a little bit concerned about the new message (from some) out there that they are " no good " anymore. Given the code on those controllers are probably not as elegant as zfs ... and given my personal preference of "being in control", I cannot dismiss the fact that some of these storage units are fast as hell, especially when you start piling on the pressure! I'm also interested to see how Sun handles this phenomenon, and how they position zfs so that it doesn't eat into their high-margin (be it low turnover) Storagetek block storage. I'm also interested to see whether they will release a product dedicated for a solaris/zfs environment. Interesting times... PS: I've also noticed some persperation on the heads of some Symantec account managers. :) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
