Dear Newbie119592
my environment:
3 Node 3 replicas
per node : 2*ssd 480G, 2* 2TB
total RAW capacity   = 2TB*6 = 12TB
total Usable capacity = (2TB*6)/3 =  4TB
Total Cache capacity  = 480GB * 6

if 10 Node 3 replicas
total RAW capacity   = 2TB*20 = 40TB
total Usable capacity = (2TB*20)/3 =  13.33TB
Total Cache capacity  = 480GB * 20
Is this answer helpful?
