Hi Herb,

I guess by "file system size" you mean "realm data size".

See http://coda.wikidev.net/Limitations

namely

"files/server: Unknown, in the order of 10^6,
limited by RVM size and average metadata/file (including directories)"

This is the limitation, the number of files per server, not their size.

Note that rvm is still 32-bit, so it does not matter if the processor is
capable of 64-bit addressing.

Note also that by creative use of multiple servers
the number of files in a _realm_ can be about 200 times (i.e. around the max
number of servers) bigger than the above.
I am not aware though of any realm doing such tricks in production.

The question has been discussed numerous times, you may find
newer and more informative threads in the archive talking of this.
