Also, there are bigger, faster external RAID boxes as well, that make the internal cards seem puny. They're nice because all you need in your main box is a good U320 controller to plug into the external RAID array. That URL I mentioned earlier that had prices has some of the external boxes listed. No price, not for sale on the web, get out the checkbook and write a blank check is my guess. I.e. they're not cheap. The other nice thing about the LSI cards is that you can install >1 and the act like one big RAID array. i.e. install two cards with a 20 drive RAID0 then make a RAID1 across them, and if one or the other cards itself fails, you've still got 100% of your data sitting there. Nice to know you can survive the complete failure of one half of your chain. > > I haven't directly tested anything but the adaptec and the lsi megaraid. > > Here at work we've had massive issues trying to get the adaptec cards > > configured and installed on, while the megaraid was a snap.

But, I'm thinking the 2.0 drivers got included in the latest 2.6 kernels, so no biggie. I was looking around in google, and it definitely appears the 2.x and 1.x megaraid drivers were merged into "unified" driver in 2.6 kernel. ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
