Hi Chang Che-Lun,

The ports in Node 0 slot 5 and Node 1 slot 5 are configured as Peer ports. Peer ports are configured with IP and used to migrate the data from one storage to another.
Peer Motion is a software that enables Storage Federation and is the first non-disruptive, do-it-yourself data migration and load balancing tool for enterprise storage.

Hope this helps.

Hi Satish

So it is a internal port or virtual port, not really a physical port ?

Hi Chang Che-Lun,

It is a physical port on the HPE Alletra Storage MP controller.

I'm not sure that this is correct.

Your Picture shows Management, iLO, and Serial Port and not these Peer Ports IPs.

@Chang Che-Lun 

These are internally used Ports, nothing to configure here and nothing to see.

Are you sure?

Hi Chang Che-Lun,

The ports in Node 0 slot 5 and Node 1 slot 5 are physical ports and they are configured as peer ports.

Hope this helps.

In Alletra MP every Node (Controller) has an internal NIC used for communication between the Nodes.
This should be this Slot 5 Port.
I will correct my first answer.
