Support for large scale storage vendors

Hi,

Initial stage of a super large system. Storage is currently estimated at 2.7 Peta, from almost 3000 cameras. The system will also need a complete 100% second backup recording and control site that allows full redundancy. Please comment on support for 3rd party vendors of large storage such as Nett APP or DELL EMC, and also if the Nx core architecture could support such a large recording array and redundancy.
