A little bit of history is in order here. The "traditional file system" was the native file system from the System/38. Today that system is called QSYS.LIB. In preparation for the advent of the AS/400, QDOC was added in CPF Release 8.0. This is a traditional PC like file system, with file names up to eight characters and extensions up to 3 characters. It was optimized to OfficeVision, so there was a lot of overhead for stuff related to OV. A number of IBM programs used that file system, and still use it today, even though IBM no longer "officially" supports it. Several releases ago, IBM supported multiple versions of QDOC, putting it in different User ASPs. (QDOC0002 for ASP 2...) In V3R1 of OS/400, these two files systems were "picked up" and deposited into the IFS, which is a more modern PC like file system, with (relatively) unlimited lengths for file names and extensions. All of the overhead for OV was dropped out of this system. This file system is all done in Unicode, which is why it has so much overhead. The EBCDIC QSYS.LIB file system resides in the IFS, which is why V3R1 sucked so badly. It was kind of like picking up a big building off a flat slab foundation, digging a basement, and putting the building back on that foundation. All of the walls cracked.

You can, however, have a QDOC library for each ASP. The maximum number of ASPs in V4R5 is 16, and this became 32 in V5R1. Independent ASPs provide another wrinkle, and they go to from 33 to 99 in V5R1, and I think more in the future. There is a very good web page on system maximum capacities and limits.
