Server / Storage Design For 75-100 IP Cameras

I am curious to know how others might design a system with a two server minimum for 75-100 IP cameras needing about 65T of storage. Do you go with two smaller servers and save off to a SAN or NAS, or do you go the other route with two larger more robust servers to cover your needs? How would you handle the expansion (as that always happens...)
