Daisy Chaining Two PowerVault MD3200

We originally bought one MD3200 array for our on-prem backup storage and one for our DR site. We recently replaced the MD3200 array on our on-prem site and would like to use the old array to double our storage at our DR site. Can we daisy chain two arrays together? Each controller on each array has 4 in ports and 1 out port as shown below. How would we cable two arrays in addition to the server that the storage is attached to?
