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.

Job Market Mysteries, Part 2

You’ve made it through two or three interview rounds, only few candidates left and suddenly a total radio silence. No call, no email, no sms, no message pigeon, no smoke signals.

Not a beep.

Deadline for the decision is long gone – You have been ghosted.

Happens all the time. No harm, no foul?

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?
