There is a specific combination of versions SRM 6.1.1 and Dell Enterprise Manager 2015 where Raw Capacity for storage array is not exposed correctly. In such versions of SRM and Dell EM provider the total raw capacity is showing much more than it is. For older version of EM provider (v2014) the capacity is correct, but in case of v2015 this can bring confusion.
As a resolution of this, SRM has adapted on EM v2015, so, even SRM 6.2 RC version already exposes the raw capacity correctly.
On following picture you can see the wrongly exposed storage array capacity:
