Hi Community,

For the Management Cluster if I have 4 ESXI hosts , Do you recommend to distributed those nodes across different racks in different chassis?

For the resouece Cluster would you recommend the cluster will include only the 8 or 16 nodes in the inclosure or will be bitter to be distributed accross multi inclousures?

To avoid single point of failure, always try to distributed your nodes across different enclosures and racks.

Thanks Rishardson,

Would it be more optimal to have the vMotion traffic inside the inclousre or you will not consider it a design issue ?

Keep the vMotion traffic inside the enclosure is a good option, but if you have nodes across enclosures, if you migrate virtual machine between enclosures, the vMotion traffic will leave the enclosure. Anyway, you can control the vMotion traffic with Network I/O or create VMs to Host DRS affinity rules to pin VMs to specific enclosures. And assuming that you have 10Gb uplinks, vMotion traffic will not be an issue higher than keep all nodes inside the same enclosure.

Thank you.
