On the main scenario page you see the Sizing specification. Here it is
- Buy
- Homogeneous – All the nodes in the recommendation are IDENTICAL
- Standard Failover
- Any storage is allowed (Hybrid or All Flash)
Automatic Sizing Options
Here you see the current Automatic sizing options
- Buy vs Rent. For Nutanix there are a few bundles that can be rented. Default is Buy and most users will leave it there
- Homogeneous vs Mixed – In Homogeneous, all the nodes in the recommendation are IDENTICAL. This means totally same model with same CPU, RAM, HDD, SSD, NIC. A mixed cluster allows Sizer to look at second model to come to optimal solution
- Failover
- Aggressive is N+0. Sizer finds lowest cost recommendation that meets the workload requirements but does NOT assure N+1 where a node can be taken down (example during upgrade) or lost
- Standard is N+1. Sizer finds lowest cost recommendation that meets the workload requirements and adds a node to assure N+1 where a node can be taken down (example during upgrade) or lost
- Conservative is N+2. Sizer finds lowest cost recommendation that meets the workload requirements and adds two nodes to assure N+2 where two node can be lost.
- RECOMMENDATION: Stay with Standard. Aggressive might be good for PoC but not in production. A key value proposition of Nutanix is online upgrades which N+1 allows. Few users go to Conservative given extra cost of 2 spare nodes
- Storage
- Any storage is allowed (Hybrid or All Flash)
All Flash – Here Sizer will limit recommendations to just All flash models
Model Filter
With the model filter can tell Sizer just find the optimal solution for the models you want to focus on. Say for example your customer has standardized on the NX-3060-G5. Just click on that model only as shown above and you know Sizer will only look at those models.
