They should have called it OS/3

  I know you are joking, but, since z/OS is the direct descendant of MVS (which stands for Multiple Virtual Storage) and predates DOS, the PC, the 8086 and most other things, it'd have been wiser to rename the PC and it's OS as SPS, or Single Precarious Storage. Abort, Retry, Fail?

    But in the mainframe world, "storage" refers to RAM, not actual storage

      Fine. Single Puny Storage.
