- 2. WEBTECH EDUCATIONAL SERIES Why Networked FICON Storage Is Better Than Direct Attached Storage With the many enhancements and improvements in mainframe I/O technology in the past 5 years, the question "Do I need FICON switching technology, or should I go with direct attached storage?" is frequently asked. This webcast explores both technical and business reasons for implementing a switched FICON architecture instead of a direct attached storage FICON architecture for mainframe attached storage. The discussion will also include an overview of the Hitachi Data Systems and Brocade solutions for mainframe environments. By attending this webcast, you’ll learn • The business and technical value of networking FICON attached storage instead of direct attached • The business and technical value of Hitachi mainframe storage capabilities • The offerings from Hitachi Data Systems and Brocade that can help you achieve the benefits of networked FICON storage

FICON INTERMIXED WITH OPEN SYSTEMS PROTOCOL INTERMIX MODE (PIM) Optional on the DCX family, Virtual Fabrics (logical switches) create isolated, independently managed domains within the same chassis frame. Virtual Fabrics (VF) create the strongest form of port isolation enabling easy upgrade migrations and very safe protocol intermixed mode (PIM) environments. Our VF, combined with VSP offers a unique opportunity to consolidate the physical I/O infrastructure while safely maintaining logically separate I/O traffic environments.

FICON BASIC SWITCHED IMPLEMENTATION DEPLOYING SWITCHED-FICON INTO DAS SHOPS FC Director Value Proposition Mainframe shops that direct attach FICON storage cannot utilize all current z/OS capabilities DCX fully supports FICON attachment to one or more Storage Arrays via mainframe CHPIDs. Switched FICON supports SCALING OUT through our ability to add additional storage ports and/or arrays without the need to add additional CHPIDs. Switched-FICON supports SCALING UP through our ability to achieve better utilization of the storage channels as well as higher levels of connectivity through the sharing of connections.
