Hi,
As far as I know, S2D will be set automatically when we enable S2D. We can calculator the S2D capacity via the following link:
https://s2dcalc.blob.core.windows.net/www/index.html
According to your information, it results in 35.2 TB of physical capacity and 3.2 TB of cache per node.
68.9TB usable, 75.1TB resiliency, and 32TB reserve. Please check if it is the same as your lab.
If the reply could be of help, please help to accept it as an answer, thanks for your cooperation!
Thanks for your time!
Best Regards,
Anne
