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!
