Hi all, I am running squid proxy server integrated with Content filter Dansguardian, squidguard and clamav for Http level scanning on centos 5 .Configured webmin management tool to create and manage access control using squidguard plug in. Now it is serving request for 100 machines and Below is my hardware details. Hardware Details SUN BLADE 6000 2.67 GHz * 1 4 Gb RAM 2*146Gb HDD we intend to scale proxy servers with around 7000 to 10000 users in future.Just i want to confirm whether the the above hardware is sufficient enough to serve 10000 users.If not please recommend me the server configuration i have to go for and also how to calculate the same. And also to prevent single point of failure is it possible to configure squid in any load balancing mode (with another dedicated server) if so just guide me how to do the same or provide me the link that best explains squid proxy server in load balancing mode. Anticipating your reply Regards, Craz paps
