Thanks for the replies! I will go with option 1: put the tempdb logfile and the logfile on a seperate disk. I can always move the logfile to another disk when needed.

To Chris: I've read your post last week. There are more replies now and it surely is helpful. Besides the fact that it is a good practice to seperate the tempdb, I also want to do rebuilds of indexes in the tempdb when needed. So it will get hammered someday. I've also talked to the SAN guy and unfortunately, he doesn't want to change the queue depth.

To Mika: In the near future it will be possible to split the disks to different LUN's, but not now. Looking forward to the future 🙂
