If the Dell EMC SC180 is made up of 4 SSDs and 24HDDS, with a total 28 disks. The minimum number of drives that can be licensed for expansion may be 28 or 14? Which answer is correct and why?
I am not sure what you are asking here.
Are you asking questions regarding your Dell Storage Center SC180?
This is not the correct formum page for that product.
You can try posing your question here:
Storage - Dell Community
Or you can always open a Service Request with Support.
Hope this helps.
