Good morning, I just received my new 3 servers for the squid infrastructure. Each server has: 2 CPU X5690 (each has 6 cores/12 threads, 3.46 Ghz) 12 GB ram (I have kits to upgrade to 24 if needed) 8 hd 146GB 15k rpm (I also have 300/600/900 GB 10k available) Actual setup are a couple of 2.7 that handles about 2500 clients, balanced via wpad. Squid sends traffic to antivirus software using a standard upstream connection. Internet connection is about 200 mbit. Now my questions: with all these cores I think that using some form of multi-instance is the best way to use them. My idea was to set 2 disks in raid 1 for boot and log and dedicate each other disk to one squid instance, 30 GB for coss and 100 GB for aufs. But I also got plenty of ram, 12 or 24 GB... so I also had the idea of a ram only squid... What would you suggest ? We are open to any suggestion, from s.o. to configuration... Thanks Francesco
