I'm a programmer and I'm involved in a project of creating something like Dropbox to offer it to the clients of a big company here in my country (online storage space+sync,etc). We are already charging the clients monthly and would like to offer them online storage space for little extra money. We already have a system that offers 98% of continuous electric supply.
I've been asked for hardware requirements, I have an idea of what's needed but would like your help. How many servers, are clusters needed, etc.
I'm also thinking that maybe we can get affiliated with dropbox (or another service) instead of creating something from scratch.
Please, can you answer roughly about the hardware requirements?
I would really appreciate it.
