What all Data Domain models support the DD Extended Retention feature?

Hi All,

I know a few DD models like DD860, DD4200, DD4500, DD7200, DD990 supports the DD Extended retention; What I am looking for and not able to find is an exhaustive list of all the Data Domain models which are capable of supporting the DD Extended Retention feature. I couldn't find it on support.emc.com

Any help in this regard is appreciated.
