understanding Compellent SC5020 utilization stats

Hi,

I am trying to understand different parameters in utilization stats, Could you please help me understand these in detail.

we are using SC5020, trying to understand the utilization statistics.

What is the difference between Allocated Space and Used Space , the help guide describes both as the same.

Configured Space — Total space of all configured volumes in the Storage Center.
Available Space — Total capacity for all non-spare disks installed in the Storage Center.
- Storage Center 7.3 and later - Available Space is the total of Allocated Space plus Free Space.
- Storage Center 7.2 and earlier - Available Space is the total of Used Space plus Free Space.
Free Space — Unused space for all Storage Types.
Allocated Space — Space used by volume data, snapshots, and RAID overhead. Beginning with Storage Center 7.3, Allocated Space is also displayed as a percentage of Available Space.
Used Space — Space used by volume data, snapshots, and RAID overhead. Prior to Storage Center 7.3, Used Space is also displayed as a percentage of Available Space.
System Space — Space used for system administration.
Storage Threshold Alert — Value, as a percentage of remaining space, when an alert is sent to indicate that disk space is getting low.
