CERN are at >100PB, which is only about 6.6 doublings, which is about right with a doubling every two, not one, years. http://iopscience.iop.org/article/10.108

Right, but does CERN connect all 100PB to a single machine?

  To a cluster fs which ZFS is not. (And not all of it.)

  No. Data is mostly accessed using XRootD[1] which can be used to data from an (almost) unlimited number of nodes. So far as I know, it's optimised for large files so the number of available inodes is limited by RAM. There is also EOS[2] which is based on XRootD and is planned to replace AFS[3] as a general purpose networked filesystem.
