NSX Reference Design Guide - Logical Switching Question

[johnggdejesus]

Hi,

I am new to NSX world and I am quite confused about this two statements below. I can't able to visualize it.

1. A transport node can have multiple NSX virtual switches.  A transport node can thus attach to multiple overlays and VLAN transport zones.

- When it says NSX virtual switches it means N-VDS? Let's say I have one Overlay-TZ-1 and two TNs (TN-A and TN-B), so if I create two segments (Seg-A and Seg-B), I would have N-VDS-Seg-A and N-VDS-Seg-B realized on TN-A and TN-B?

2. A transport zone can only be attached to a single NSX virtual switch on a given transport node. In other words, two NSX virtual switches on the same transport node cannot be attached to the same transport zone.

- If TN-A and TN-B is part of TZ-1, when this statement comes into picture? Does it mean that N-VDS-Seg-A and N-VDS-Seg-B cannot be attached to Overlay-TZ-1?

Technically with VDS7 and NSX3.X you shouldn't deploy with NVDS, but use the VDS option.

Each host supports a single overlay transport zone on a single host switch (VDS for simplicity), but as many vlan transport zones as you want.  If you want additional overlay transport zones, they will need to be on a separate host switch with their own dedicated pnics.  So what you described is possible, as long as you meet these requirements.

I believe this answers both your queries.
