Project and Program: MVS, MVS Core Technologies

Tags: Proceedings, SHARE in Anaheim 2012, 2012

What is a Ficon "exchange" and how many do I need? What is Buffer-to-Buffer credit, and how does it affect a Ficon fabric? How does MIDAW help me? Given by the Ficon firmware team leader, this presentation will provide the answers to these questions by describing the basics of the Ficon architecture and the internals of a Ficon Express channel. Topics will also include the steps the channel goes through to pass commands and data to and from the control unit. Dale F. Riedy ; IBM Corporation
