0 min RPO as sync rep is not possible due to 6ms RTT. Requires <5ms RTT Central DC: 75TB per node Remote DC: 50TB per node. Based on 6.5 document. Near sync and Async 1h is support. Lowest is 15mins https://portal.nutanix.com/page/documents/details?targetId=Leap-Xi-Leap-Admin-Guide-v2022_6:ecd-ecdr-resource-requirements-r.html

On nodes that have storage greater than 64 TB (80 TB for all-flash nodes), the minimum supported snapshot frequency is six (6) hours. For such nodes, this limitation has the following consequences: The minimum supported RPO for asynchronous replication is also 6 hours. NearSync is not supported. Any cluster that includes such a node is also subject to this limitation. https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_15:wc-dr-near-sync-requirements-limitations-r.html

On nodes that have storage greater than 40 TB (48 TB for all-flash nodes), the minimum supported snapshot frequency is 6 hours. For such nodes, this limitation has the following consequences: The minimum supported RPO for asynchronous replication is also 6 hours. NearSync is not supported. Any cluster that includes such a node is also subject to this limitation. This limitation does not apply to hypervisor snapshots
