Hi all. Maybe this seems the already-asked question about Squid sizing. I had a look at the faq, searched the list archives (and google) but I did not find a satisfying answer. I have some experience as a Linux admin, with some Squid installations, but only for small sites. Now I was asked to propose a squid based solution for url filtering of the web traffic of 12.000 users. The speed of the Internet connection is 54Mbit/sec. Unfortunately at the moment I am not given the amount of http requests per second, but I suppose that web surfing is not the main business of these users, so they are not going to use all that bandwidth with http. I was asked if all this can be done with just a cluster made of 2 machines for availability (which would be appreciated, since tha main point seems to be url filtering, not necessarily to save bandwidth), or if it is mandatory to implement a cache hierarchy. I thought about some scenarios. In the worst one I assumed I need 400 Gbyte of storage for cache and about 10 Gbyte of RAM. I would like know if it is possibile (and safe) to run such a Squid machine. In particular, I wonder if I'm going to run out of file descryptors, available TCP ports, or there are other constraints I should think about. Or if maybe I should better consider splitting the load on a set of different machines. Thank you Luigi
