Roger, As an original joint study team member with IBM when I was working for LSI Logic, let me add my two cents. I don't want to rewrite the FAQ because you've done a pretty good job but let me add some old lore and nostalgia.
There was a parallel network backup project called ESMS (Enterprise Storage Management System, maybe?) that was an MVS-based repository for backup data. Back then (early '80s) there were not many "workstations" other than PCs running DOS and later Win2 and Win3, some Sun-3-class machines and some early IBM workstations called RT (real turkey - heh). Needless to say, ESMS never saw the light of day as a product. WDSF was the brainchild of this brilliant guy (I think his name was Norm Pass) who wanted to backup all of the "workstations" down at Santa Teresa Labs in San Jose. He was an expert in VM, data management and he liked to support workstation users and give them that extra effort that made their life better. As I recall, and I may be wrong on this, he started up this project with no budget, no staffing and no official support from IBM. It was solving a problem through creative and intelligent execution. We were starving for a backup solution at LSI Logic at the time and we were closely engaged with IBM because we were a big VM user back then. Basically, WDSF was this home-grown system that met the requirements of IBM and that's about it. I truly believe that Norm never dreamed his creation would become ITSM and have the impact on the computing world that it has. The early days had very crude TCP/IP stacks and the VM one was dependent on some external hardware that was extremely primitive. Of course, IBM was pushing Token Ring but Norm knew the value and future of TCP/IP and it was a part of what made WDSF so good at the time. I can still remember the first pitch he gave us down at Santa Teresa with his casual (for IBM) but enthusiastic attitude. I remember him saying how he borrowed spare hardware and bodies in their spare time to pull it off. It was truly a grass-roots ad-hoc project (again, by IBM standards). As I also recall, in the later days when it was officially a product, it was developed and supported out of North Carolina. The development platform was AIX (that's what I could get out of them when I asked) and they ported to everything else. If someone can verify this information, especially about Norm Pass and the early development days, that would be great. Please don't include any of this lore until it's been verified by someone else who was involved in WDSF/ADSM back then.
