Hmm, this is potentially interesting. We're using PERC 6/i with 4 x 10k 2.5" 146GB drives in RAID10. I currently do a straight-forward CentOS install onto the logical drive, creating two partitions, one small one for /boot and the other across the rest of the disk which I make an lvm PV and slice it up using lvm. The main performance bottleneck for us is write performance for MySQL. Could I get better performance by doing things differently? R. -- "Feed that ego and you starve the soul" - Colonel J.D.
