Insight on partitioning a LAMP Server design issue

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

I have no issues with your partitioning scheme, but a few questions. Why
have /dev/sda RAID 1 and /dev/sdb RAID 5? I thought that a single RAID
volume required 2 separate physical volumes volumes.
Secondly, I would probably want to use LVM to give you greater
flexibility so you can resize and move things around.
