Re: Transparent proxy, Hardware requirments

I'd run with an absolute minimum of 4 GB cache (that's *cache*, not the
whole system), preferrably more along the lines of 8-16 GB. You'll want to
put lots and lots of RAM, 128 MB is probably an exceptable minimum
although more might be better.

I'd suggest at least three drives -- one for the system, one for Squid and
its logs, and one for the cache. The Squid-only box I'm building to go on
line this August (we're adding a bunch of lines and caching clients) will
run with 16 GB of cache (4 seperate 4 GB drives with different cache_dir
entries), a 2.2 GB UWSCSI drive for the system, and another for Squid and
its logs. The processor will be either a Pentium Pro or a Pentium II
(depends on cost issues when we purchase the motherboard and processor in
in June/July). It will have somewhere between 128 and 256 MB of SDRAM
(depends on cost at the time). It will be running a hacked up version of
Redhat Linux 5.0, unless the 2.1 kernel is working by then. Ethernet card
will be a 3c905 running into a switch.

If you really expect you cache to take a beating I'd reccomend you either
stripe some disks together with md for your cache, or run several seperate
drives with different cache_dir entries. You can really speed up your
cache by splitting up disk activity over multiple drives as well as
running on a box with lots of RAM. Processor may be the least important
part.

And make sure to use a BusLogic SCSI card if you run Linux. BusLogic at
the moment appears to be the best supported SCSI card under Linux.
