Reading this article from The Register, it would appear CERN are generating about 1PB per day from the LHC run.
It seems they keep all their storage on site but it’s quite likely that they might have less important or lower priority data hosted in a cloud provider.
And it being a scientific institution I’m sure they’ll be cost conscious.
That’s definitely not a scale the network is currently ready for. Also, the reason they store it locally is probably because they need to have that close to a computer cluster as well to churn through all that data.
And yeah, nuclear research in this context means research about the nucleus. It’s “just” particle research. I’d say the name is actually a little outdated, but CERN has become a recognized name in its own right.
Let me link to a suggestion I had made in the past where Storj could offer Storj DCS as storage solution:
We also had this in the past:
As already mentioned, research facilities and universities usually have already their solutions and they often have very very capable IT departments because they have the knowledge, the money and the people to build what they need on-premise. But still Storj might be a part of their solution for example when it comes to distribute datasets around the world.
