Hey Joseph,
You meant SAS? yes?
To decide about hardware specs you will want to try and measure the
requests per second rather then the amount of users.
Another thing to take in account, is it a regular forward proxy or
intercept\trpoxy?
Do you want to keep logs on local disc?
Do you have specific objects\sites you want to cache rather then having
a cache proxy?
Take in account that squid is a single process and not threaded.
Squid works faster(in general) with separated DISKS for a cache_dir
rather then having them in a RAID array.
Things about ram:
About 10-15MB per 1 GB of cache_dir.
Each live connection consumes about ~60-70 KB of ram.
Hope this will help you make more calculations
Regards,
Eliezer

Hi All
I am trying to make the hardware specs for the SQUID cache server.
I have around 600 users, they may be using the bandwidth from 500dbps to 3Mbs.
Expected annual increase of users will be up to 20%. I would like to size the
hardware specs for the server, which will be enough for next coming three
years.( user may be up to 900 then)
What specs should I go for?
For fast r/w I will go for SCSI hard disk, but I am not sure about the amount
of RAM, CPU power and harddisk space for disk cache.
I would like to request guidance on how to determine the hardware specs
Guidance requested.
Thanks
Joseph John
