I think that zFS was introduced in z/OS 1.2, but definitely in 1.4. At that point we were running Lotus Domino on z/OS and had really bad performance problems on the huge HFSs needed for the Domino data bases. zFS wasn't any better. We converted to zFS at IBMs recommendation, but ran into a host of problems. We converted back to HFS, and the performance problems went away due to the 'reorganization' of the HFSs. By now, Domino runs on zLinux because it turned out to be a cpu hog that couldn't tolerate being told NO by the lpar dispatcher. Still is a cpu hog, for that matter, but on IFLs now. We are still running HFSs, and will be for some time, I think.
