It also played a major factor in the enormous number of distributed 4300s that started in the late 70s ... large customers ordering hundreds at a time for deployment out in departmental areas (non-traditional datacenter locations, stock rooms, former conference rooms, etc). Issue was getting system support down to dozens of systems per support person rather than dozens of support people per system. For awhile they tried to attribute the lack of MVS being deployed on the thousands of distributed 4300ss on the fact that the only CKD disks were the high-end 3380s (not suitable for non-datacenter areas), the mid-range (3370) and low-end (3310s) were all FBA. Eventually a CKD 3375 was announced (3370 with CKD hardware emulation) eliminating that as an excuse for MVS not being deployed into the thousands of distributed 4300s (back to the issue of requiring dozens of support personnel per system).
