The 3x 1TB drives in a s/w RAID5 is seeing all drives so the DSS Lite is seeing 3TB and is over the amount, you can purchase a 2TB storage license key from the link below if you wish to use the free amount of 2TB that we offer for free.
I've tried adding the backup drive to the other server machine, which has a RAID5 setup across three 500GB drives it seems to be accepting it w/ a lite license.
the S/W RAID setup shows all 4 drives, the three 500GB drives are in a RAID5 array of 1TB, and the 1TB ESATA backup
exact values are 931.51, 465.76, 465.76, 465.76 GB
an exact conversion of that works out to 2.27TB
yet it isn't saying the limit has been reached like the other machine,
Does it allow the total to go slightly over the limit or something?
