I have upgraded to operations manager v4 (from v3.7) and installed the OMED. ~ Easy, no problems
The report has many numbers on it but I am not sure how well I am doing compared to what is possible? I have 13 filers and 1,000 disks and my global report states:
Storage Utilisation 53.3% (38.6% raw) and Storage Efficiency 94.1% (67.9% Raw).
The biggest savings 64% come from RAID-DP which I believe to mean I have saved X Tb by not using the extra disks required for RAID 10.
What sort of numbers are you getting?
