Crazy Compression Numbers SC4020

Anyone using compression on their Compellent?  I just enabled for our 2 large file server volumes (~2 tb each) and am seeing some crazy numbers in Enterprise Manager.  It appears that it compressed almost 1.3-1.5 TB of data into ~50 GB.  If so, thats one<ADMIN NOTE: Profanity removed as per TOU>of a compression algorithm! 

Maybe I'm just misunderstanding what is going on here?

For example:

Configured Space: 2 TB

Free Space: 477.52 GB

Total Disk Space (WHAT????): 142.16 GB

Actual Space: 1.62 TB

Active Space: 1.53 TB (1104.76%)

Replay Space: 90.45 GB (63.62%)

Savings vs RAID 10 (WHAT AGAIN?): 3.09 TB

On the other hand under Disk space saved through compression its showing ~5.72 GB.

Somewhere the statistics must be off... Right?
