Hi I want to create a 2-node squid reverse caching layer for an apache server that has these features: - 2 Xeon@ 2GHz - 2 GB RAM - 72GB HD RAID1 - RHEL with Kernel 2.6.9 - 1 EXT3 filesystem Traffic is a million visits/month My question is, how much disk space should i allocate for caching data on the squid nodes? my idea is to use amazon Ec2 instances for them, but i dont know how much disk space should i use for caching data under this scenario... Any recomendation will be welcomed! Greetings
