I always wonder about that as well. However, part of it may be some "special deals" that they got from their vendors. If that were published, then many other, smaller, customers might be upset.

Why do you say that packed fields must be replaced with zoned (display) fields? I would likely replace them with either 2, 4, or 8 byte integers, depending on the range needed. I don't know of any system, other than the z10, which implements decimal floating point yet, so I would not use that. > > One shop I know of that attempted this (CICS based) took 10 times the > floor space to replace 1 z800 box and the RAID box, the 3745s (2), the > tape drives with "OPEN" systems.

Well, the tape drives, if in an ATL, should take up about the same floor space. Open Systems DASD always seems to be at least 2x the mainframe size. I guess because of the difficulty in expanding individual file systems. This latter has been addressed by the Sun zfs file system. Now that is an interesting file system, with some nice features, including resizing "on the fly". Also "snapshot" capability in the software. Not perfect, but better than any other UNIX file system that I've read about.
