If you plan on implementing HCI to support your workloads and are looking to size an environment, the vSAN ReadyNode Sizer tool is the place to go.
There are 3 ways to use this.
- Don’t log in – use the tool in “Evaluation” mode
- Login using your My VMware account
- Login using your Partner Central account
In “Evaluation” mode you’ll be able to create some basic configurations for general purpose workloads but will have no ability to customize or download the sizing results.
If you log in using your My VMware account or Partner Central account, you’ll have a lot more functionality. First, you’ll be asked if you want to configure an All Flash cluster or Hybrid cluster.
Previously, the only place to size a Hybrid cluster was using the old vSAN Sizing tool. The ability to configure Hybrid clusters was just added to the new tool so now there is one place to size either option.
Next you’ll be asked if you want to size for a “Single Workload Cluster” or “Multi-Workload Cluster”
The Single Workload Cluster provides options to configure for VDI, Relational Databases, or General Purpose workloads.
The Multi-Workload Cluster choice is I helpful if you plan to have different types of VM’s and want to input the various workload specifics. There are a ton of customization options including block size, IO Pattern, vCPU/Core, etc. And of course, either option allows you to choose what vSAN protection level and method for each workload. You can even size for stretched clusters.
Our great product team at VMware has put a ton of work into this tool including some complex math to come up with a simple and easy way to configure clusters for vSAN. Check out the tool and see for yourself. But, also, feel free to contact your favorite partner or VMware Systems Engineer to also help. The vSAN SE team has done hundreds and thousands of these configurations and can help make sure you’ll be good to go.
