I have a doubt regarding Active Control Path , how it is connected say if i have 2 Disk shelf will it be 2 individual cables coming from filer to disk shelf's or 1 cable comes from filer connects to disk shelf from that disk shelf it will be going to another disk shelf ???? . please help me to understand this.
ACP is in effect a daisy chain between all entities in your HA storage system.
You come out of one NetApp FAS controller and go into a controller on the disk shelf and then through the same controllers on that stack; then daisy can the stacks together and before you know it you are back in the other controller.
The cabling diagram that ships with any new system or new shelf can help with this.
