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?

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?

“Top three things that you shouldn’t say in your job interview”
Surely you have seen posts with lists like these many times?
How come both lists contain the same answers?

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.

When I originally designed DPTPB Nutanix Dynamic shapes, I intentionally left out validity checks for disk sizes. This was done to save some time when making the shapes and reduce complexity in both using and making the shapes.
Supported disk sizes with NX appliances are changing over time, not just when a new hardware generation is released, but also with new AOS releases as more drives are qualified to be used with NX appliances. These changes in supported disk sizes should also be carried to the DPTPB Nutanix Dynamic shapes, by making updates to “disk size” lists and code associated with them.
This update requirement also meant that if I was lagging behind or skipping “disk size” updates, the shapes would slowly deteriorate and might be frustrating to use, especially if more stringent disk size usage rules or validity checks were in place. To give some freedom to end-users with the original dynamic shapes, there were no rules with mixing disk sizes, all supported disk sizes per platform were available to mix and match freely.
With disk size validity checks users might not be able to fully document environments if the Nutanix spec sheets were updated with new “disk usage rules” and the dynamic shapes lagged behind with updating this information.
But hold on.
Now that there is possibility to use custom disk sizes with the dynamic shapes, changes in supported disk sizes and updates to the dynamic shapes lagging behind would not be such a huge problem. Users could use custom “Generic” and “Manual Entry” disk sizes and get the drawing done with correct disk sizes while waiting for me to update the shapes. While not a perfect solution as you might end up with unsupported combination, but a feasible workaround.
Hmm, Maybe I should consider “disk size” validity checks again…
