I just purchased a HP ProLiant DL380 Gen10. I have 6 2.4TB drives configured with RAID10 ADM. When I load Windows, I only show I am getting just under 5TB. If my calculations are correct, shouldn't I get over 7?ILO RAID Config
Am I wrong in my calculations?

7.2TB, to be precise.  You do lose some to overhead (you need a way to find all that data, after all), but 2TB seems excessive.

Is this capacity a limitation of the RAID controller?

From the numbers: You have two spares (a spare leg or one per strip set)?

RAID ADM is triple mirror. so you should see 4.8TB.

Not that I read. Plus I can connect 10 drives to this controller.

Andy is correct. ADM denotes a special mode. See page 111.
