For non-VxRail nodes it is supported to add any node whose server is on the ESXi HCL for the version in use and has controller(s),SSDs+MDs that are on the vSAN HCL.
However if you are using VxRail, new nodes need to be identical hardware to the ones in use.
To confirm understanding. The translation does not help much to me that I do not understand English well.
If I were using native vSAN, I could grow without rule of hardware capability (CPU, memory, and disk). Of course, there should be a good practice of using disks with the same speed and capacity for better performance.
For vxRail Dell environment is different, unfortunately.
That means in the future, in some 3 years, for example.
If I do not find the same hardware, can not I grow my environment?
Will I have acquired another vSAN environment?
I read that I could always grow with better hardware in CPU and memory. However, the discs need to be the same size.
I could just be remembering how it seemed back when it was Quanta nodes (e.g. pre-Dell) - these were sold as 4-node 2U units and I recall them being fairly strict compatibility-wise. I will ask one of my VxRail colleagues whether node additions are a different situation now with Dell boxes.
Thanks for the help.
This is a question that many end users ask, aiming for future growth.
