I sync from ESnet's Mirror, And with dvd's I'm at 138GB, I've seen it up
to 160Gb, I'd allocate it 200GB.

The base system is running Varnish (http://varnish-cache.org/) with 32GB of RAM cache and a 10Gbit/sec network uplink. PNNL has multiple 10Gbit/sec links to ESnet (http://www.es.net/) and the Pacific Northwest GigaPOP (http://www.pnw-gigapop.net/).

When a new release hits the street, the most popular CD and DVD ISO images should stay resident in the Varnish RAM cache. We hope this strategy lets us get away with relatively inexpensive / high capacity disk drives while still achieving good network throughput.
