Yes, there are multi-petabyte systems out there. Though you may disagree, I personally don't think its unreasonable to expect such filesystems to pass the 16 exabyte range within the next 20 years. Neither did the ZFS designers, hence the 128-bit capability.
Note that we are talking about filesystems, not individual disks. ZFS filesystems can span any number of disks, just as you could achieve by layering on top of a volume manager or through a distributed filesystem. Besides just being flat out larger, the growth rate of filesystem size not directly proportional to the growth rate of disks. - Eric On Wed, Oct 12, 2005 at 07:50:49PM +0200, Joerg Schilling wrote: > Eric Schrock <[EMAIL PROTECTED]> wrote: > > > There is little expectation that anyone will be able to fill a ZFS > > filesystem, ever[2].
