We have a 4 node vSAN configuration, and each host has 3 disk groups.
My question is about the number of capacity in each DG. Is there any advantage or disadvantage with performance if use 1 8TB drive vs. 2 x 4TB or even 4 x 2TB drives?
I know using a smaller drive will limit the future storage growth, but will having multiple SAS ports in play help in performance?
I have been looking for an answer to this everywhere but haven't found one yet. Any comments are appreciated.
