Nearsync - Max Cluster TB and Backup

We are currently considering implementing NearSync for a DR with an RPO of 15 minutes.

 

Is there still a cluster limit of 40TB in 5.16? I can't find anything more specific in the documentation. https://portal.nutanix.com/#/page/docs/details?targetId=Prism-Element-Data-Protection-Guide-v5_16:wc-dr-near-sync-requirements-limitations-r.html

 

The restrictions that backup tools like rubrik or netbackup cannot take normal snapshots when nearsync is active should be solved in 5.9 or not?

Hey Scout, 

 

I have read this doc and in the topic AOS Snapshot Frequency for Nutanix Nodes detail few scenarios about replication. Now is possible to look new limitation and requirements to async and NearSync. Sample:

 

 

Sum up, I think that there isn't more limit of the 40 TB through node. About I didn't find out nothing.

 

Good day,

Best Regards.

So that means new limit for Nearsync in Hybrid Disk is 64TB, I guess.
