Viewing Disk Space Usage Summary
Use the Data Progression Pressure Report to make intelligent decisions on the types of
disks to add to a system. The System Manager groups disks by disk type. Data Progression
uses Dynamic Block Architecture to move data to performance-appropriate and cost-
effective disk tiers. For each Storage Type, the Data Progression Pressure Reports window
displays how space is allocated and consumed across different RAID types and storage
tiers.
