Max number of shelves in a stack

[D_BEREZENKO]

What is the max number of shelves in a stack?

Can't find it in the document SAS Disk Shelves: Universal SAS and ACP Cabling Guide

nor in SAS Disk Shelves: Installation and Service Guide For DS4243, DS2246, DS4486, and DS4246

It is a little cryptic, but you need to go to http://hwu.netapp.com/Controller/Index and select your version of ONTAP and the controller model. After you click the Show Results button there will be a link labelled "Compatible Shelves/Drives" which will contain all the information you need.

As a general rule it is 10 shelves per stack, but there are limitations when using the low end controllers and/or SSD.

You can also find this info in Storage Subsystem Technical FAQ

HWU as you've just told not providing such an information. But Storage Subsystem Technical FAQ does.
