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

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

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.

CUP (Control Unit Port) on the DCX Family provides an interface to z/OS for performance reporting and management.

Mainframe / OPEN in Same Director Infrastructure

Provides improved business agility

‒ Quickly deploy new applications ‒ Quickly re-deploy storage assets between Mainframe and

OPEN systems ‒ Storage virtualization permits non-disruptive movement of

data within the virtualized storage network ‒ Data movement between Mainframe and OPEN systems

can be enhanced through shared networks and virtualization

Improves overall storage performance

‒ Mix 8Gbps FICON and 16Gbps Fibre Channel

‒ 16Gbps for virtualization and ISL’s.


Mainframe / OPEN in Same Director Infrastructure

Virtualization of data center storage will make use of

16Gbps technology on the OPEN side until FICON

devices have the same capability.

Improved utilization of Director technology.

‒ Fewer ISL’s with 16Gbps

‒ Higher Fan-in / Fan-out ratios.
