I suppose you are referring here to linux software raid (mdadm), right?

If that's the case, you can have the number of volume partitions under 
the RAID1 your system can manage. In fact, that's the usual setup, I 
mean, if you have two physical hard disks (sda and sdb), you'll have md0 
(sda1+sdb1) for /boot, md1 (sda2+sdb2) for /, md2 (sda3+sdb3) for /home, 
md3 (sda4+sdb4) for /var, etc... 

What is not a good idea is to share/mix "non-raided" partitions with 
"raided-ones" because an error in one of the disks will expose the 
running system. It is thus recommended to have all the partitions in a 
disk holding raid volumes inside a raid set.

But still... is this "a perfect" setup? Maybe not and some people would 
instead recommend adding LVM over the RAID 1 to make your disk layout 
even more flexible and configurable over the time. 

But note that's something that will add "two" extra layers of complexity 
in your configuration (first, the software raid and then, the LVM) and 
while that setup can be seen as an advantadge, unexperienced users could 
easily make fatal mistakes (with data loss) while setting it up. Again, I 
would prefer running whatever tests you need to do from a virtualized 
environment where you can break things without having to worry the day 
after :-)
