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
