Unofficial DPTPB Nutanix Dynamic Visio Shapes: NX-1120S-G7 & Minor updates

Nutanix has released a new NX platform, NX-1120S-G7 a while ago. I’ve been waiting for Nutanix to update their official Visio stencils, but Nutanix seems to have lost interest in maintaining their official Visio stencil set.

So I decided to make my own NX-1120S-G7 Visio shape. As there were no original “donor” Visio shapes to be used as a base for the new shapes, I had to “eyeball” the new shapes, so they might not be 100% accurate, but are good enough…

While I was at it, I also made some minor updates to existing shapes, like new supported disk sizes / combinations, new 100GbE NICs and new GPU options.

Unofficial DPTPB Nutanix Dynamic Visio Shapes: NX-8170-G7 with partially populated NVMe bays

In my earlier post describing NX-8170-G7 and NX-3170-G6 DPTPB Nutanix Dynamic Visio shapes, I was hoping more supported disk layouts for NX-8170-G7:

I am happy to finally see option to have a all-NVMe setup for the most I/O hungry workloads. But it is my sincere hope that Nutanix will add more supported disk layouts for NX-8170-G7. Or at least give us option to partially populate the NX-8170-G7 with NVMe drives.”

It seems that my wish has been granted 🙂 As of AOS 5.18 partial population of NVMe disk bays is now supported. (Only with with AHV, not with ESXi or Hyper-V, not sure why)

Making this update was fairly straightforward. Only one line of code changed, a list containing supported disk configurations for NX-8170-G7. The  dynamic nature of DPTPB shapes took care of the rest.

Unofficial DPTPB Nutanix Dynamic Visio Shapes: NX-3170-G7 & Minor updates

In my earlier post describing NX-8170-G7 and NX-3170-G6 DPTPB Nutanix Dynamic Visio shapes, I was surprised to see that NX-8170-G7 only supported NVMe drives and I was missing a direct G7 generation equivalent for NX-3170-G6. It seems that I wasn’t the only one missing NX-3170-G7 and after all Nutanix decided to introduce NX-3170 also with G7 generation.

So it is time for me to update my Unofficial DPTPB Nutanix Dynamic Visio shape collection. Additionally there has been some changes in supported disk / NIC combinations for existing G7 generation NX appliances and I’ve modified the shapes to reflect these changes.

Nutanix Hybrid Selection Guide

In earlier post I went through some Nutanix spec sheet issues and while describing some disk size related issues, I made SSD/HDD capacity ratio calculations with Nutanix Hybrid (SSD+HDD) setups. I used only couple of SSD+HDD setups and Nutanix NX platforms as an example.

  • Why not go through possible SSD/HDD ratio ranges for more NX platforms?
  • Find the floor and the ceiling for SSD/HDD ratios?
  • It might be useful in selecting NX Hybrid setup for workloads with certain requirements for SSD/HDD ratio?

Nutanix Spec Sheet Errata

The official Nutanix G6 & G7 generation NX appliance spec sheets are frequently updated and are getting better with every iteration. Unfortunately there are still issues with them. Some information in the NX appliance spec sheets is confusing and showing conflicting or wrong information and should be corrected. Some of the aspects of NX appliances are documented in fairly shallow manner and could benefit from more comprehensive documentation.
