vSAN/Dell Support Question

Hi All

I am currently in the process of putting together a spec for a 3-node vSAN. I have a couple of questions regarding Dell support for the hardware.

I have a spare R730XD in stock from a previous purchase. My plan is to purchase from Dell 2 more R730XDs with RAID/HDD/SSD on the vSAN HCL. They are in fact part of this ready node configuration however; I will be using different processor/RAM quantity and different NICs. For the existing R730 chassis that I have, I will purchase the components (the same as the other 2).

One of my supplier quoting for this has thrown a spanner in the works and pointing out the following:

1. Because I am not using a vSAN ready node configuration, Although RAID/SSD/HDD are on the vSAN HCL, Dell won’t ‘fully’ support the configuration. I am not sure what this means and they were vague. They made it sound as though hardware vendors will not support vSAN configs that deviate from the ready node configs.
2. Using the existing 730XD chassis may also not be supported by Dell because it was not purchased as a vSAN ready node – Maybe something to with firmware.

My understanding is that as longs as applicable hardware is on the vSAN HCL then you are OK, as Dell will support the hardware as it is purchased from them. Is anyone able to verify these 2 points?

Many thanks
