Two best practices have been updated on this week. The Nutanix DR and Backup Best Practices is located in the Support Portal.
The update was around bandwidth sizing and added a link to Wolframalpha which spits out the sizing formula for you.
The vSphere and Commvault Best Practice Guide added some guidance around IntelliSnap and sizing. At this time IntelliSnap and Metro is not supported but streaming is a fully supported option.
