Going very much above 30 Mbps of HTTP traffic with a single Squid
server is not very practical. For such configurations it is
recommended to use a farm of several servers, each with 4 drives for
cache. For 50-70 Mbps I would use a cluster of 3-4 servers, where one
of the servers optionally also acts as load balancer with LVS if you
do not have a separate load balancer available (optionally HA-enabled
by LVS clustering with one of the other cache servers).
Note: You will probably not be able to use all space on the cache
drives. The number of drives is not for space but for the number of
heads to reduce seek time. See the Squid FAQ on memory usage for
cache space/memory dimensioning.
If this traffic is not only HTTP traffic but lots of other traffic
such as P2P file sharing, email, native FTP etc then the calcualtions
will obviously be different. Squid is only involved on HTTP or HTTP
proxied traffic (i.e. ftp by HTTP clients configured to use Squid as
proxy), not other unrelated traffic.
