Thanks Dan_O.
I figured out that was what we needed. I have been advised we can't get the cards so had to go with the SAS unit in the end. Do you know of any documentation on how to configure SAS expansion devices to work with this chassis? I was hoping that i would see the LUNS from the expansion unit on the MFSYS35 modular server control but i don't. Does this just pass through the SAS connection meeing that allocating hosts must be done on the external device?
Thanks
Mark
