Hi, I have a WIN2K server with a mirrored RAID array with 80GB IDE drives. I would like to add more storage and was thinking about adding 300GB drives that I would also want to be a mirrored array.

What I would like to know,,, can I add a second controller card to the server that will run the 300GB array for storage and leave the existing controller in to manage the 80GB array with the OS?

In all likelyhood, yes.  Provided that:

1) You have a PCI (or whatever) slot available for the new controller.
2) There are enough free system (i.e. IRQ, DMA, and I/O) resources available for the new controller.
3) There are software drivers (if required) available for the new controller.  For a new controller this should not be a problem.

As noted above, it should work fine.  HOWEVER, check the manual for your current controller.  Many controllers can support multiple arrays -- if yours does, you can simply add the drives and use your current controller to manage both arrays.

you could also create a software RAID if performance is not an issue and you have two interfaces open. (ie: if your using it for back-ups).
