DD2500 has either 7x or 12x 3TB disks internal to the controller - referred as 21Tb or 36Tb (raw).
Depending on whether it was sold as 12 disks or upgraded, you get useable; ~11Tb (7 disks), 21Tb (7+5 disks) or ~25.9Tb (sold as 12 disks). Figures are approximate.
You can add up to 135Tb of external storage shelves on top of the above in the controller.
That is made of a max shelf count of 3, and so 3x 45Tb shelves (3Tb disks).
You will get around 32.7Tb per (45Tb) shelf useable.

DD2500 can support expansion disk shelves. I believe you have one card/port and can expand to 4 ES30 (normally you would need redundant connections, but according to https://support.emc.com/docu58943_Data_Domain_ES30_Expansion_Shelf_Hardware_Guide.pdf?language=en_US&language=en_US DD2500 is exception. You can visit https://store.emc.com/us/Product-Family/DATA-DOMAIN-PRODUCTS/Data-Domain-DD2500/p/DDM-DataDomain-DD2500 and select chat option - they can check what you have and tell you exactly how much you can upgrade.
