RE: Adding parity and mirroring to a 170

So if I am to understand you correctly, adding the 7102 expansion unit, all
I have to do to add mirroring is add another 2 4gb drives and 1 more 8 and I
will be able to mirror them out correct?  Or do they ALL need to be the same
size?

we will have to add a raid controller card

Uh, so far as I'm aware, 170s (and 40s-es and 510s) are RAID-ready out of
the box.

All you need for mirroring is an even number of each size/model of drive.
And all you need for parity is enough of each size/model to make a parity
set. So far as I'm aware, there is no special controller card required.

Which is to say that we have a 40s, a slim 170, a fat 170, and a 510, and
they're all mirrored, and we didn't have to buy anything to do it, other
than drives.
