Basics: RPA Ports/Replication
Hello RPA Community,
I am having some difficulty understanding the setup and working of the RPA's so hoping someone can help me find my answers. I'm guessing I will have more questions as my learning continues.So to start with can someone please assist me on:
- The LAN port is a Copper connection.I assume this is to manage to the devices on our local LAN in each DataCenter? I guess this will also hold the VIP between the 2 RPA devices in each DC?
- The WAN port is a Copper connection. Can someone tell me what this is for? Is this the cable over which Replication happens? What if I want to replication over FC rather than IP.Would this port then need to have a Fiber SFP installed to it and then connect into my Brocade switches, rather than my Network Switch as it currently is with a Copper cable?
- I have 4 unused copper ports. What can I use these for?
- The 4 Fiber ports in each RPA connect to my Brocade switches. I'm guessing this is how my RPAs see the Local Storage and the Array Splitter sends the RPA's data to be replicated from the local Array? How is the Remote RPA (and therefore Storage) reached? I will have a dedicated 1Gb cable presented to me from our DC team in the form of a fiber cable that connects to our remote DC. If I want to use this cable to send replication traffic over, how would I do it?
I know lots of questions. But really confused. Thanks for any detailed responses in advance.

- The LAN port is a Copper connection.I assume this is to manage to the devices on our local LAN in each DataCenter? - YES I guess this will also hold the VIP between the 2 RPA devices in each DC? - ASSUMING BY VIP YOU MEAN VIRTUAL IP ADDRESS, WHICH IS THE MANAGEMENT OR CLUSTER IP ADDRESS, THIS CAN FUNCTION ACROSS BOTH THE LAN AND WAN PORTS.
- The WAN port is a Copper connection. Can someone tell me what this is for? - THIS IS FOR IP REPLICATION BUT ALSO FOR INTRA AND INTER RPA COMMUNICATION Is this the cable over which Replication happens? - FOR IP, YES What if I want to replication over FC rather than IP.Would this port then need to have a Fiber SFP installed to it and then connect into my Brocade switches, rather than my Network Switch as it currently is with a Copper cable? - IF REPLICATING OVER FC YOU WOULD CREATE A ZONE PER FABRIC FOR THE RPAs FROM BOTH CLUSTERS. EACH OF THE RPA HAS A SINGLE 4 PORT FC CARD WHICH WOULD ALSO BE ZONED FOR ARRAY CONNECTIVITY. HOWEVER, THE WAN PORTS SHOULD ALSO BE ASSIGNED IP ADDRESSES TO ALLOW COMMUNICATON BETWEEN THE LOCAL RPAs (INTRA) IRRESPECTIVE OF THE FC MODE OF REPLICATION.
- I have 4 unused copper ports. What can I use these for? - SEE ABOVE ANSWERS.
- The 4 Fiber ports in each RPA connect to my Brocade switches. I'm guessing this is how my RPAs see the Local Storage and the Array Splitter sends the RPA's data to be replicated from the local Array? - SEE ABOVE ANSWERS. How is the Remote RPA (and therefore Storage) reached? - SEE ABOVE ANSWERS. I will have a dedicated 1Gb cable presented to me from our DC team in the form of a fiber cable that connects to our remote DC. If I want to use this cable to send replication traffic over, how would I do it? - THERE'S NO SUCH THING AS A 1Gb FIBER CABLE PER SE.

Hello Forshr. Thank you so much your time and effort in responding. I hope you didnt mind the basic questions. In 5 mins you have cleared up answers that I have been trawling the internet to find over the last month. Maybe I just dont know where to look!!
Regarding the 1Gb fiber cable. Can it be such that it is restricted to 1Gb and dedicated for FC SAN Replication?
Another couple of question I then have is:
- Is Sync Replication possible over IP?
- Where can I get access to this wealth of information/resources?
Once again, thank you.

Regarding the 1Gb fiber cable. Can it be such that it is restricted to 1Gb and dedicated for FC SAN Replication? - I PRESUME THEY MEAN A LOGICAL 1Gb PIPE.
Another couple of question I then have is:
- Is Sync Replication possible over IP? - YES BUT WITH A RRT LATENCY OF <= 10MS.
- Where can I get access to this wealth of information/resources? - IF THIS IS AN RP/SE INSTALLATION THEN THE RP/SE QUICKSTART DOCUMENTATION CAN BE DOWNLOADED SEPARATELY OR AS PART OF THE RP/SE INSTALLATION KIT FROM EMC ONLINE SUPPORT OTHERWISE YOU CAN DOWNLOAD THE RECOVERPOINT INSTALLATION AND DEPLOYMENT GUIDE.

Hi Forshr
Thanks for your response. Yes, I assume it is a logical 1Gb pipe... to me its just a cable that Ive been told connects to the remote datacenter and is dedicated dark fiber... with a "1Gb x-site Dark Fiber" label on it.
I will try and find this documentation today.
Thanks for all your help so far

Forshr, just to be sure, during a local replication CDP with RP/SE, RP monitor anyy new wite from the Source LUNs by FC, if the host make a write over the Source LUNs then RP write over the replications LUNs by FC correct?
And I can have Sync or Async Local replication over FC?
In this case LAN ports will be used just for Management and WAN ports for RPA internal communication.
