I'm wondering why they need "dual 20 core processors, 786GB of memory" to serve FTP?

Operated by csc.fi, so it's perhaps just the standard server for a science oriented org. Or a maybe a "hand me down" from them.

  So I actually live (and am typing this) about 5 minutes walk from the CSC head office in Keilaranta, which I can see out of my window. I wonder if the machine is physically located there. (I'm pretty sure my first linux kernel download was 1997, one of the 2.0-pre series, and it probably came from funet.fi)

They can serve a lot of users simultaneously. Most of that RAM will be file cache.

  Yup, the niche science site may have a big working set for a single server to handle a worldwide random workload, but it is still cost effective versus trying to pay for a CDN that will have such low user density. The conventional science community approach is volunteer mirror sites. We could have many benefits of a CDN without the big recurring costs.

FTP is not the only service provided, see http://ftp.funet.fi/README http://ftp.funet.fi/README

  Also see [1] Very old (inter)network, also ran an IRC server back in the days. IRCnet IIRC [1] https://en.wikipedia.org/wiki/FUNET https://en.wikipedia.org/wiki/FUNET

  This does not answer my question, I've read the site and the README: what do you see there that I didn't see?

It has less to do with capacity required for the task than it has to do with justifying the IT manager's budget and general dickwavery. Although, if IT really needed to justify its budget, today it'd be talking about how many AWS nodes they use and how big their Kubernetes cluster is. To serve FTP.

You may as well ask why big systems are needed for anything. You can run Postgres on a 10 year old laptop, but you can't run Postgres on a 10 year old laptop as a backend for the USPS.

  I didn't know USPS had such high requirements. Where can I learn more about this?

  An SQL database workload I would understand, but an FTP seems mostly filesystem/io not memory and cpu bound. If you have more information, I'd be happy to have the details.

My guess is that they're mostly optimizing to minimize impact on other operations and effort needed to host this - 80 TB storage from shared system might be nothing compared to needs of scientific computing, but letting requests directly there might be too much - having lots of cache at frontends will take care of that, and dual processors are needed to have that much memory. And dual frontends will give nice redundancy.

  Thanks, this is pretty much the only real answer to my serious question here
