Limitations on combinations
•
Maximum of five high workload IOPs per bus.
•
Maximum of three dissimilar high workload IOPs per bus.
•
In #5044 System Unit Expansion Rack, no DASD controllers are allowed on the same bus with a 3590
tape controller.
Note:
•
These guidelines are for all system buses and include the first system bus.
•
Exceeding these guidelines will cause performance degradation.
Certain tape devices listed in the above table are also supported by the #6534 Magnetic
