Unofficial DPTPB Nutanix Dynamic Visio Shapes: Disk Size Validity Checks

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…

Unofficial DPTPB Nutanix Dynamic Visio Shapes: Why unofficial shapes?

Some of you might wonder why this shape collection or stencil set is unofficial. Since I’ve also created the G7 and G6 generation official Nutanix Visio Stencils, why not make them official?

Here is why…

Visio by DBPTB: Official Nutanix G7 Visio Stencil

Nutanix is refreshing their appliances to G7 generation hardware which will eventually replace G6 generation hardware. Transition is done in phases, first platforms to get G7 refresh are already released multi-node models NX-1065-G7, NX-3060-G7 and NX-8035-G7, followed by single-node models NX-3155G-G7, NX-8155-G7. Additionally single node NX-8150-G7 reappears in the model lineup.

The fate of remaining G6 platforms NX-1175S-G6, NX-3170-G6 and NX-5155-G6 has not been released yet. I would expect them to be updated in some form or other, but you never know until they are released, some might be dropped or altered. If these models are crucial to your future Nutanix projects, please check the availability and specifications for G7 variants from your local Nutanix Rep.

The official Nutanix stencils will be updated following new hardware releases. The latest stencil package can be found from Visiocafe. The initial update will include new NX-1065-G7, NX-3060-G7 and NX-8035-G7 shapes, more shapes will be released as time goes on. This stencil release also includes fixes for some scaling issues, namely using Nutanix shapes with Viso “No Scale” page settings or Visio “Blank drawing” templates.

You might also want to take a look at Unofficial DPTPB Nutanix Dynamix Shapes, which are more user friendly and faster to use than the official Nutanix shapes, while at the same time provide capability to produce more detailed drawings. Even if you don’t care about the advanced dynamic features, I recommend using the dynamic shapes as they contain some bug fixes for the official Nutanix stencil.
