Tags: Proceedings , SHARE in Boston 2013 , 2013

Performance in a FICON network is influenced by the underlying flow control mechanisms of Fibre Channel. In this session, we examine how Buffer-to-Buffer credits flow from the channel to the control unit. We also look at how exchanges are used in FICON applications and how they change with the introduction of zHPF. During both examinations, we explore the role of the FICON Director in managing Buffer-to-Buffer credits and exchanges over a cascaded network. Throughout the session, we debunk the various FICON 'Urban Legends' featuring credits and exchanges. Take the opportunity to learn from two of the FICON industry's leading experts in channel and fabric development and join our session. Howard Johnson; Lou Ricci Brocade Communications Systems; EMC
