An administrator is responsible for the following Nutanix Enterprise Cloud environment:
A central datacenter with a 20-node cluster with 1.5PB of storage
✑ Five remote sites each with a 4-node cluster with 200TB storage
The remote sites are connected to the datacenter via 1GB links with an average latency of 6 ms RTT.
What is the minimum RPO the administrator can achieve for this environment?
For nodes with storage greater than 64 TB, the minimum supported snapshot frequency is six (6) hours. Given that the central datacenter has a 20-node cluster with 1.5PB of storage, this means each node has significantly more than 64 TB of storage. As a result, the minimum supported RPO for asynchronous replication in this environment would be 6 hours. NearSync is not supported for these larger nodes, reinforcing that the correct minimum RPO is 6 hours.
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

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
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
