Indeed.

On Isilon's website we find:
* Up to 10.4 petabytes and up to 85 GBps of throughput and up
  to 1.4 million IOPS in a single file system.
* Add capacity and/or performance within 60 seconds.

I don't know how Isilon does this but think of how one would
build a FS that can scale to multi perabyte files requiring
multi gigabyte/sec bandwidth and ability to add storage as
needed. Think oil companies and movie studios!
