We're currently looking into our options in regards to caching data for a new application.  Varnish seems to be a good solution, but I haven't found much information in regards to the maximum cache size.

We will be serving 10's of thousands of users with potentially 800GB-1TB of "hot" data in millions of files.

How does varnish scale with large cache sizes, both in terms of the amount of files, and the size of the total cache?  This is assuming the hardware to support such an operation is in place.
