Probably the best explanation of Redundancy Factor vs. Replication Factor. There have been some changes with current versions, it would be great if @nutanix would update this video.
Its absolutely confusing for me because in 5.11 those 2 options are called "redundancy factor:: both in cluster setup and in storage container settings. So I can have redundancy factor 3 for cluster and redundancy factor 2 for a container. I am lost...................
This is how I understand it. RF used have two meanings, redundancy factor AND replication factor. The former refers to cluster HA. The latter refers to data replication. So, with the consolidation of terms to simply "RF" you have to consider the entity for which you are configuring RF. If you are configuring RF at the container level would refer to the number of copies of data. If you are configuring RF at the cluster level, it refers to the number of failed cluster components that you can sustain.
Hi Jaiveer - this is not as much of a calculation as it is a configuration setting. Including some details below... To see the cluster 'Redundancy State', log into Prism Element and click the gear in the upper-right corner. Scroll down under 'Data Resiliency' and look for 'Redundancy State'. That will tell you how the cluster is configured (most clusters are Redundancy Factor 2). If your cluster is five or more nodes, it can be set to Redundancy Factor 3. Assuming that to be the case, then containers can be configured with a Replication Factor of 1, 2 or 3, otherwise they can only be Replication Factor 1 or 2. The container configuration can be viewed by selecting 'Storage' in the main dropdown on the upper-left side of Prism Element. Once there, you can select 'Table' and get a view of the 'Replication Factor' of each container. Again, these will typically be set to '2' as most clusters are deployed with a Redundancy Factor of '2'. Our 'Prism Web Console Guide' details each of these settings/terms. I am including a link to the AOS 6.5 guide directly to the 'storage' section where most of this is discussed. If you search the guide for 'Redundancy Factor' (a cluster level setting) or 'Replication Factor' (a container level setting), you should find all of this info. Hopefully this helps! portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_5:wc-storage-management-wc-c.html

Thanks for the feedback, Jonathan. We are currently in the process of evaluating which videos need a refresh and this one is due. Stay tuned!
Best explination! Thanks!

How to calculate replica factor and please provide direct link for this
