depends on your shelfs
i think mk2 can be up to 4 or 8 according the LRC/ESH module

have a look here : http://now.netapp.com/NOW/knowledge/docs/hardware/NetApp/syscfg/
choose your ontapp version
then
select your filer and select disk shelves

you probably can read :
<<
Note: When the disk shelf has LRCs, the maximum number of disk shelves per loop is four.
>>

-> understand "8 shelves otherwise"... as i read it from another machine/ontapp page

<<
Note: When the disk shelf has ESHs, the maximum number of disk shelves per loop is six and the first shelf in the loop must have optical modules.
