HW RAID 1+0 is generally a win -because- you don't need a lot
of the space.
Lop off a 2GB LUN for the qmail queue.
Oh, your external firewall needs a high-performance qmail-queue too?
There goes another 2GB LUN. That's right: EXTERNAL HW RAID generally
can be configured for multiple hosts.
Use the rest as protected mailbox storage or generic "network attached
storage".
Enjoy the praise you get for the high i/o performance.
