Sun's long awaited 128-bit Zettabyte File System (ZFS) is close at hand, set to be available for use as early as this month. ZFS, a 128-bit filesystem that has advanced redundancy and the ability to be used across multiple volumes and multiple systems, has been in the works for over 4 years and was thought, for a while, to be vaporware. It will be a standard option with Solaris 11. How it will compare to other like filesystems such as NFS isn't for sure, but it has been highly anticipated and has a lot of features designed for newer technologies such as multiple operating systems on single servers. It'll only be available for Solaris, of course.
