We have a SC220 that had a space issue a couple of months back. With Dell's assistance we got the issue resolved by dropping a raid level and clearing a lot of old  data.

The solution we have has 3 Tiers. 

Write Intensive SSD 6  x 400GB (1 Spare)

Read Intensive SSD 6 x 1.6TB (1 Spare)

7k's 1TB x 12 (1 Spare) 

 

 

The Tier 3 Storage is pretty much at 100% 

Tier 2 is at 35%

Tier 1 is 6 %

 

Is there a pathway to replace the 7 K's with larger disks or will removing further data (reluctantly) bring this down?

 

Thanks
