Nutanix Sizer


I have recently been involved in becoming a partner for Nutanix and completed the NPP certs.  Its pretty cool tech and I can only see the hyper-converged market getting stronger over the next few years.  Once you are a partner you have access to the partner portal / support portal / community edition and the Nutanix community.  One cool tool is the Nutanix Sizer tool which allows you to design your solution and spit out exactly what model and how many nodes will be required.  The following will run through an example VDI solution.

To become a Nutanix partner start here

The sizer lets you create scenarios that can be tailored to your requirements.  I chose the workload type -VDI

Sizer1  Sizer2

Select your VDI broker, in my case it is Horizon View.  Enter the workload type of a typical user, for the example I have selected Power User.  The table alongside shows what defines a Power User.

You can customise this further if you wish, set the gold image size and average IOPS for example

Sizer5

Set the required replication factor – either 2 or 3.  This is the number of copies of the VM data for this workload.  Choose to enable Erasure Coding or not – this is space saving mechanism which states a saving of up to 70%.  Erasure Coding is described here.  Choose also to have a dedicated cluster or not, you may want a management cluster for instance.

Complete this and your presented with a cool looking dashboard full of treats.  It defaults to standard but you can change it to conservative – aggressive and the dashboard changes the spec for you.  It displays the CPU/SSD/HDD and RAM usage excepted for that hardware running the configured workload.  In my example it is configured for 600 users with Power User settings

You can see the rack space required along with the wattage.  You can drill into some of the figures by selecting Sizing Details

And if you dont trust the tool you can specify the hardware to your spec

The scenario is then saved into your portal and can be accessed at a later date.  The scenario is listed with a nice summary page.  you can go back into the workload and add to it, for instance you might have multiple sites with different workload settings
