I did not load the linux drivers from dell, it works so i figured i was not going to worry about it. This server is so oversized for its load its unreal. I have always gone way overboard on server specs and making sure its redundant. The difference in our bonnie++ numbers is interesting, In some cases my setup blows by yours and in other your's destroys mine. On the raid setup. I'm a windows guy so i setup like its windows machine keeping the OS/logs way separate from the DATA. I chose to use ext3 on these partition ---- Message from Craig James at 03-13-2008 07:29:23 AM ------ First, did you get the Perc 6i with battery-backed cache? Not all versions have it. I found this really confusing when trying to order -- we had to work pretty hard to figure out exactly what to order to be sure we got this feature. (Does anyone at Dell follow these discussions?) Second, Dell ships a Linux driver with this hardware, and we installed it. I have no idea what the driver does, because I think you can run the system without it, but my guess is that without the Dell driver, it's using the Perc6 card in some "normal" mode that doesn't take advantage of its capabilities. With a 6-disk RAID 10, you should get numbers at least in the same ballpark as my numbers. Craig
