Max size for ddup storage

Hi

I am in th process of removing the tape backups from my enivroment. I backup 12tb on a single month end. I am planning to put in 250tb of disk in a Puredisk pool.

I run 7.6.1 on a 2012r2 server.

I am not clear if i will be able to use the full 250tb for a Puredisk pool, as you can only have one Puredisk pool per server this may make my 250tb a bit overkill.

Any info would really be helpfull.
