Assuming you mean using Liinux software raid, sure, you can do that.
When you create your LVM volume, instead of using a physical
partition, like say /dev/hda2, you'll just reference an md device,
like say /dev/md0.
While it may be technically possible to raid your /boot, I'd recommend
you save the headaches and not bother with it. Same for swap, don't
use a raid for swap.
If you're really serious about building it out "the right way", go
with a single drive that will house /boot and swap space, smallish,
like 2-4 gb. Add to that a hardware raid adapter and the drives. You
can use LVM on the RAID volume. Most distros seem to just make 3
partitions these days, /boot, / and swap. There are plenty of reasons
to splinter the filesystem further, such as keeping /var and / apart
from /home so that user activity won't crash the box if they run their
filesystem out of space.
It really depends on how the box is being used. The best advice I
could give about this? Think. Think some more. When you're done -
think again. You'll be glad you planned it all out down the line.
