Greetings,

I have a FAS3040 running 7.2.4 that is used primarily for LUNs over FCP. I balance most of the filesystems across four LUNs in two volumes groups spread across both controllers. I would like to add additional space, but was wondering if there were best practices in terms of buying two shelves at a time (like some other vendor's models) or if a single shelf is okay. Since I spread the space across both controllers, is it okay to distribute the disks on a single shelf to both controllers? Will this affect RGs or performance in any way?

TIA,

Daniel
