Simplification mostly. Why do it if I don't have to?
This box is a redundant backup for another (with older hardware, I had
no choice but use software RAID on that one). But since it is a backup,
I have the luxury of taking one down to tinker with the arrays while the
other takes over full time, so I wasn't convinced that the cost of
complicating the setup with things like LVM or mdadm would be worth the
perks. At least in my case.
I'm open to arguments for or against if anyone has any feelings about
it, as I'm nowhere near sure that the setup I'm using is the best thing
to do.
What
happens when you need to add more drives than that one controller can
handle?
The case and controller are already maxed out at 16 drives. If I need
more space, then I'll probably just upgrade to larger drives and rebuild
the arrays.
I'm facing just such an upgrade dilemma with the older box now. Some of
the older drives are beginning to fail, so I have a choice: buy more
drives of the same size to replace the failing ones, or start buying
larger drives and start upgrading the arrays.
