Good afternoon, Our company is currently investigating the use of Squid as our Proxy solution (Secure Web Gateway?). I was curious if anyone out there has successfully installed and managed a Production Squid environment that would be about the complexity and size of the following (and I'd like some information on it): 1) 3,000 concurrent users 2) Three sites Primary Site: 100 Mb/sec Internet Connection Secondary Site: 30 Mb/sec Internet Connection [This is used for a DR scenario only] Tertiary Site: 45 Mb/sec Internet Connection [This is used for a DR scenario only] 3) We are a Windows 2000/2003 Domain. It's a single forest with two (2) Child Domains. There is a firewall between the two (2) child domains. 4) We need HA Pairs at each site, but because we have VMWare ESX 3.5 implemented at each site we are throwing around the idea of using 3-4 virtuals (or however many you guys would recommend) and using our DR strategy for VM's to V2V to boxes to the other two (2) sites. Your input, comments, and questions would be greatly appreciated, thanks!
