RecoverPoint for Migration over FC
My Customer has an existing vblock at site A. it's currently replicating to site B, using RecoverPoint over WAN.
Site A: (Cluster 1) site B: (Cluster 2)
VMAX40K (vBlock) --- 5 x RPAs Gen5 ======>> 5 x RPAs Gen5 – Vplex -- VMAX3 AFA
They just bought new VMAX AFA recent at site A, and new RPAs for both sites. And the target config is as below, over WAN as well.
Site A: (Cluster 3) site B: (Cluster 4)
VMAX3 AFA (vBlock) --- Vplex ---- 4 x RPAs Gen6 ======>> 4 x RPAs Gen6 --- Vplex -- VMAX3 AFA
For migration purpose, we want to leverage RP between the Cluster 1 & Cluster 3 over FC. Generally we need to put all cluster 1 FC ports and all cluster 3 FC ports in the same zone. The challenge in this environment is RPAs in Cluster 1 & 3 are on separated vBlock MDS fabrics, so we cant zone them together directly.
The option we are thinking is to connect half of Cluster 1 RPA ports to Cluster 3 RPA fabric. That means half of RPA ports are used for local splitting/journaling, and the other half dedicated for remote replication. Does that sound like a viable solution? if not, what other options we have? Thanks in advance.

Hi there,
No problem at all, it's a viable config. As long as there's at least 1 RPA port per fabric (so that target RPA/storage is accessible via at least 2 paths), you should be good.

Great. Thank you Idan.
On the configuration details, Cluster 1 and 3 have slightly different number of RPAs. I assume that's fine as long as we use the first 4 RPAs only?
Currently Cluster 1 is using port 0 & 2 on each RPA. so we will connect the same 0, 2 ports from Cluster 3 RPAs to the Cluster 1 fabric. And create one big zone per fabric to include all 0, 2 ports. Does that make sense?
Thanks again.

Yes,
We don't officially support mismatch number of RPAs but assuming this is temporary and you're using only the common RPAs, you should be good.

Hi Idan,
In the original post:
"That means half of RPA ports are used for local splitting/journaling, and the other half dedicated for remote replication."
Does it matter if port 1 of existing RPA zoned to port 0 of the new RPA for CRR replication? I assume it doesn't matter? Thanks.
