As for hardware, there are 60 bay rackmount chassis out there that you can outfit with 60 20TB drives, which would give you just over 1.2PB. You would need a motherboard with enough PCIe lanes to use the needed number of HBA cards. If you went with HBA cards that can support 16 drives, you'd need 4 for 60 drives. I personally use the Pro WS WRX80E-SAGE SE WIFI, which might be overkill for your scenario, but the 7 16x lanes allows me 4x HBA cards + 1 GPU for Plex hardware transcoding/Steam streaming + 2 Hyper M.2 expansion cards for cache.
