rp4vm mult site protection
hi
i have 3 sites
Site A: Main Site
Site B: Sync Site
Site C: Async Site
question 1 / scenario 1: can we replicate a CG from Site A to Site B sync and then from Site B to Site C async (Cascade replication ) ?
Question 2.1 scenario 2 : can we replicate a CG from Site A to Site B sync and from Site A to Site C async (one to many )
Question 2.2 scenario 2 : if we replicate a CG from Site A to Site B sync and from Site A to Site C async (one to many ) and Site A failed and we failed over to site B, would be able to resume replication from Site B to Site C for that CG.
Environment : Latest VxRAIL cluster on each site
Link :Dark fiber between all sites with very low latency
distance between Site A and Site B 150 meter and 40KM to Site C

Hello mousa.elian,
It is best to open a support case for this custom setup that you are wanting.

RPVM supports concurrent replication. Up to 4 replica copies for each CG. As for q2.2, upon failover from A to B, B->C would be configured and a full sweep would initiate. Every full sweep doesn't necessarily replicate all the data set as we read prod and replica, compare and replicate only the diffs so, in this scenario, little data would be replicated over the wire.
