Unofficial DPTPB Nutanix Dynamic Visio Shapes: NX-3155G-G7 & NX-3155G-G6

More in depth notes regarding NX-3155G-G7 & NX-3155G-G6 Dynamic Visio shapes.

While NX-3155G-G7/G6 front-view shapes are as easy to use any other dynamic shapes, mixing NICs and GPUs with NX-3155G-7 and NX-3155G-G6 rear view shapes has added some complexity.

You might save some headaches by checking this documentation before trying the NX-3155G-G7 and NX-3155G-G6 rear-view shapes, if you opt to NOT to use automated placement of NICs/GPUs and decide to place them manually. Even more so than with NX-3170-G6.

In dynamic / automatic mode NX-3155G-Gx rear view shapes are as easy to use as any other dynamic shape and should not cause any headaches.

Default mode of a dynamic shape

NX-3155G-G7_Front_Default

When a dynamic shape is pulled to a drawing it looks like any normal non-dynamic shape as by default all the dynamic elements are turned off.

However you have an option to make your shape to show more detailed information by using pull-down menus in “Shape Data” and the shape will automatically adjust its appearance based on your selections.

This design decision was made to:

  • Have more uniform look for the shapes when pulled to a drawing for the first time
  • If I had chosen to use one of the dynamic configurations as a default look
    • The default might not have been the right one
      • Better to show no info than wrong info
  • With “clean slate” look you can manually populate NICs and such with separate NIC shapes if you so desire
    • Without having to disable the dynamic features first
    • Most of the time there is no need for manually populating NICs
    • Manual functionality mainly is reserved for
      • exceptions
      • or
      • To have ability to continue working in case some spec sheet changes have not yet been updated to shape parameter files

Using “Shape data” Window to modify the dynamic shapes

Access “Shape Data” window (Visio 2016)

  • “View” – “Task Panes” – “Shape Data”
  • or
  • Select a shape – Right Click – “Data” – “Shape Data”

“Shape Data” menus are also Dynamic

  • It shows only relevant info / sections
  • For example if you choose All Flash disk layout, you can only choose the size of SSD drives, no menu for HDD size

“Shape Data” shows any data relevant to currently selected shape

  • No data visible = check that you have selected correct shape

Dynamic Front View Shapes for NX-3155G-G7 & NX-3155G-G6

NX-3155G-G7_Front_all_flash

By making selections in “Shape Data” window pull-down menus you can change the appearance of your shapes. The built-in automation will populate dynamic elements within the shape to match your selection.

NX-3155G-G7/G6 shapes have similarities with NX-8155-Gx shapes, but NX-3155G-Gx front view shapes have some modifications when compared to the original “parent shapes”. NX-3155G-Gx supports only six disks, while NX8155-Gx can have upto 12 disks. Additionally there are differences between the G7/G6 generations of NX-3155G rear view shapes as there are differences in which disk bay disk drives are placed.

Dynamic Rear View Shapes for: NX-3155G-G7 & NX-3155G-G6

NX-3155G-G7_Rear_PCI_Slots_2GPUDW_2NICS_real_shapes_labels

While dynamic rear-view shapes for other NX models are fairly straightforward to use and you might have skipped reading the documentation, with NX-3155G-Gx rear view shapes it is my strong recommendation to read the documentation before trying the shapes. As a result of mixing GPUs and NICs with the shapes, NX-3155G-Gx shapes by far the most complex shapes in the dynamic shape collection. 

Bad news: Using these shapes can be more complex and it might be difficult to get it right 

Good news: the NX-3155G-Gx shapes have built-in automation to place the elements correctly and you don’t usually have to worry about it, unless you decide to skip the automation and instead place GPUs / NICs manually by using separate GPU / NIC shapes

By making selections in “Shape Data” window pull-down menus you can change the appearance of your shapes. The built-in automation will populate dynamic elements within the shape to match your selection.

The rear view “parent” shape is the same for NX-3155G-G7 and NX-3155G-G7, the differences are implement by using different parameter files. Rear view shapes for NX-3155G-G7/G6 support using GPU shapes.

PCI Slot usage order or priority

Like with other platforms there are rules regarding PCI slot population with NICs and GPUs with NX-3155G-G7 and NX-3155G-G6. With other platforms the rules are fairly logical and easy to follow, they might say: NIC1 always goes to PCI slot 2. And there are no exceptions.

Unfortunately with NX-3155G-G7/G6 it is not so simple as there are quite a few exceptions to these rules.

The rules might change depending on:

  • the type add-on-card (NIC or GPU) used
  • the form factor of the GPU used
  • the type of NIC used
  • the type of GPU used
  • the generation (G6 or G7) of the NX-3155G-Gx

PCI slot orientation and form factor

Additionally there are different PCI slot orientations (0° / 180°) and NIC form factors in use (LP/FH).

Too many combinations makes life hard

Various combinations of exceptions, PCI slot orientations and form factors makes the usage of the shape somewhat complex. I’ve tried to alleviate most of that complexity with automation that prevents users selecting combinations that are not supported.

PCI slot numbering with NX-3155G-G7 / NX-3155G-G6

NX-3155G-G7_Rear_PCI_Slots

  • Lets start with numbering the PCI slots so you can follow the rest of the documentation
  • My PCI slot numbering is slightly different than what is used in the official spec sheets
    • The official spec sheets won’t have PCI slot 4 and call it PCI slot 3 instead
      • They state that various adapters are connected to PCI slot 3, when in fact they are connected to the fourth PCI connector / slot (counting from the bottom)
    • For me this doesn’t make much sense, so I have both PCI slots 3 and 4 in my documentation
      • If you need to connect something to PCI slot 4, logically it is connected to the fourth PCI connector / slot (from the bottom)
      • According to current spec sheets nothing is really connected to PCI slot 3
        • When in use DWFH GPUs will occupy / block PCI slot 3
          • But are still connected to PCI slot 4
        • In the future this might change
          • and something could be connected to PCI slot 3
          • Had I been using term “PCI slot 4” when actually talking about “PCI slot 3”
          • -> lot’s of now very confusing documentation to be fixed

PCI Slot Orientation with NX-3155G-G7 / NX-3155G-G6

NX-3155G-G7_Rear_PCI_Slots_with_orientation

  • While were are at it, let’s cover also PCI slot orientation
  • To illustrate PCI slot orientation in the example above I’ve flipped the text in PCI slots which are in 180° orientation
    • 0° orientation
      • The text runs in normal orientation
      • PCI connector is on the left side of the NIC / GPU
    • 180° orientation
      • The text runs in upside-down orientation
      • PCI connector is on the right side of the NIC / GPU
  • Why is orientation important?
    • In real life there are NO separate NICs for different orientations
    • When you install a NIC in 180° orientation
      • you have to flip it in order to
      • line up the PCI connector of the NIC with the PCI connector in the PCI slot
    • Once you flip a NIC
      • NIC port order and port numbering also flips
      • Typically with
        • 0° orientation, port #1 is the leftmost port
        • 180° orientation, port#1 is the rightmost port
    • If you don’t take orientation into account you might mess up your cabling
      • and cable NIC port#2 to switch X
      • when you were supposed to cable NIC port#1 to switch X
      • while assuming that NIC port#1 is always the leftmost port
        • when in fact NIC port#1 is the rightmost port with NICs installed in 180° orientation
    • With GPUs the orientation is not that important
      • No ports or port numbers flipping around to potentially mess up your cabling

  • NX-3155G-G7 supports only maximum of two quad port 10G NICs
    • and Quad port 10G NICs have different PCI slot usage order than the rest of the NICs
    • Why? I have no clue, but I am sure that there is a valid technical reason for this as it is explicitly stated in the spec sheets

      • but because it is so wide it also blocks the usage of PCI slot 3
  • GPU2
    • N/A as it would have to go to the same PCI slot as NIC2
    • It looks like there would be room for GPU2 using PCI slots 1 & 2
      • Not supported
        • For unknown technical reason
        • maybe stacking two powerful GPUs into adjacent PCI slots might produce too much thermal load in that region?
    • It looks also like there would be room for GPU2 using PCI slots 6 & 7
      • Not supported
        • For unknown technical reason
        • Slot 6 is not used with NICs (or GPUs) with NX-3155G-Gx platforms
        • Maybe there is a HBA (for disks in PCI slot 6)?

Limitations

Differences between NX-3155G-G7 & NX-3155G-G6 dynamic shapes

Generic Differences

  • There are differences with PCI slot usage priorities
  • There are differences with supported number of NICs
  • There are differences with supported type of NICs
  • There are differences with NIC orientation
  • There are differences with NIC form factor
  • There are differences with supported GPUs
  • There are differences with supported disk types
  • There are differences with supported disk sizes
  • Differences are implemented by using different parameter files and additional coding
  • The actual differences are updated ONLY in the parameter files NOT here.
    • This way I don’t have update the information in two places

New features and bug fixes

Even if you are not interested in using the dynamic features and just want to use the basic static shape, it is my recommendation to use the dynamic shapes anyway. The  reason for this recommendation is that the current Official Nutanix stencils set contain some bugs that are fixed in DPTPB Dynamic Nutanix Visio shapes.

How would you know? I also made the official stencils 🙂

Why aren’t they fixed in the official stencil? – No funding

NX-3155G-G7 & NX-3155G-G6

New GPU shapes

  • More visually appealing GPU shapes
  • Totally new GPU shape
    • Nvidia T4
    • Missing from the official stencil set

Fixes for NIC orientation and port order

  • NICs are now placed into PCI slots in correct orientation
  • NIC ports are now in correct order (depending on NIC orientation)
    • If NIC is placed in 0° orientation, port 1 is the leftmost port
    • If NIC is placed in 180°, port 1 is the rightmost port
    • Normally there is no need to care about NIC orientation as automation takes care of the orientation with the dynamic shapes
      • But if you want to manually populate the NICs with separate shapes, you have use the correct variant of the NIC shape
  • Not specifically stated in spec sheets, there are some pictures where you have to figure out this by yourself

More visually appealing NIC and NIC port shapes

  • Better visual cues about NIC orientation

More unified coloring of the shapes

  • in the official version of the stencil multiple shades of gray was used with front and rear view shapes

“Yellow” dots or connection point “usage hints” now removed

  • Since all the elements are placed correctly in automated fashion, there is little use for these hints
  • While they were useful feature with non-dynamic shapes where you had to manually place NICs and such, they were slightly problematic
  • The correct Visio term for “Yellow Dot” is “control point”
  • Besides giving usage hints, “control points” can be used to move elements within a shape
  • Even though I had disabled the moving feature of “control point” they made moving the shape harder
  • When you clicked a shape to move it, you might have clicked a “control point” instead and you couldn’t move the shape
  • You had to click the shape in an area that was not close to “control point” in order to move the shape
  • The further zoomed out were, the harder it was to click a portion of the shape that was not close to a “Yellow dot / Control point”
  • i.e. when heavily zoomed out, it was harder to move a shape within a drawing
