Hi Darren

You register the AMP only on its side of the cluster

For example

if you have a VNX in Site A and a VMAX in Site B

Then you would register the AMP for VNX in Site A only

Register the AMP for VMAX in Site B only

Example B

If you have a VNX and XtremIO in Site A and VMAX in site B

Then in Site A you would register one AMP for VNX, Then register an additional AMP for XtremIO in Site A

So 2 x AMP in Site A

Then in Site B you would register one AMP for VMAX

Hope this helps

Any other questions let me know

Kind Regards

Tadhg
