Could use LVM to stitch it all together... What I tend to do is have a secondary controller (e.g. a 8006-2) with 2 drives as a simple mirror for the OS, and then use all the drives on the 9550 for the data partition. My latest system even has those 2 drives in a hot-swap carrier accessible from the back (in addition to the 24 drives accessible from the front). But, yes, creating multiple arrays (or enabling auto-carving on the 3ware) will work as well. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
