A frequent question I get is related to Nutanix capacity sizing. Sizing Nutanix is not complicated and Steven Poitras did an excellent job explaining the process at The Nutanix Bible (here).
However, as the Nutanix cluster grows overtime and different HDD/SSD capacities are introduced, the calculation starts to get a little bit trickier; specially when the resiliency factor for containers are different.
One of Nutanix Sr. Product Managers, Avinash Shetty, created this awesome (unofficial) Nutanix capacity sizer that you can use to simulate RAW and Usable capacity based on SSD/HDD sizes and quantities, as well as based on the Replication Factor in use and the total number of nodes.
The calculator also provides you with the capacity allocated by Nutanix CVM to each component (Cassandra, OpLog, Content Cache, etc..) providing a detailed view of how your Nutanix cluster will look like from a capacity standpoint.
