Hi there,
I need to setup a proxy server for my company= with squid, There are
more than 10,000 users that will connect with= this proxy for access
to the net, I wanted to use a Redhat 7.3 or 8= provided they allow me
to use huge amount of RAM something to a tun= e of 16GB, what I wanted
to know is btw these two which ver to choos= e for this kind of memory?
I also need to run IPTABLES and a VirusWa= ll on the server, can anyone
suggest weather to use a single server = for proxy, IPTABLES and Virus
Wall with 16GB of ram or I should use = some other architecture???
Waiting Eagerly for your Reply.
Thanking You.
Regds,
Abhishek Gupta.

16GB just for a proxy seems overkill to me. Is this RAM figure derived from some realistic calculations?
a proxy server would benefit from 1. a faster and larger hard disk array (this is to be used by page cache) 2. multiple, load balanced NICs (so that max no of users can be served at once)
so instead of going in for a 16gb ram server, you can put the money in above two areas.

Correct me if I'm wrong, but 16GB RAM isn't even addressable on a 32bit machine. 32bit address bus == 2^32bytes of addressable memory == 4GB of addressable memory MAX. This includes RAM + Swap.

Use a smp machine. 4 processors will be capable of using 16gB. However a load balancing architecture with vanila pcs is a lot better.
Thats an issue, you could look at a 64-Bit platform such as AMD Opteron if you really need so much of RAM.

Greetings,
Optreon is not really a necessity AFAIK Kernel 2.4 onwards support large RAM with Intel PAE
The PAE extensions allow up to a maximum of 64GB of RAM that the OS can address.
Correct me if I am wrong.

This calculation is the basic rule and you are correct with that. But this is applied only to older servers. Newer servers (or processors) support PAE (Physical Address Extension) that allows you to address upto 64GB of RAM. So that figure is possible...but still unaccepteble for the situation. See this, or just google for PAE

Just rememebred,
There is PSE36 as well in almost all newer processors and AFAIK Suse 8.0 kenel natively supports this and loads itself in HIMEM of 4GB

Yes, Linux can support more then 4GB of ram using Intel's PAE (Physical Address Extension) features PL go through this link http://www.spack.org/index.cgi/LinuxRamLimits for more information

OKAY, By now we seem to have discussed about 16GB of memory can indeed be accessed on modern servers.
Now I think we should focuss on the requirements of original problem...Abhishek's further inputs are awaited eagerly.
Meantime, can we decide upon the server configuration, I mean, is 16GB really worth spending for a proxy server?
I think we need some more inputs from the Abhishek, mainly -> What is the outgoing line (T1, ADSL, Ethernet...) -> What is the incoming network (10Mbps, 100Mbps, Dialup(seems unlikely)...) -> What is the current infrastructure available (layout of switches, machines,..)) -> What is the budget -> what is the maximum likely number of users connecting at once
