  • Troubleshooting FICON
    Send documentation comments to [email protected] CHAPTER 16 Troubleshooting FICON Fibre Connection (FICON) interface capabilities enhance the Cisco MDS 9000 Family by supporting both open systems and mainframe storage network environments. Inclusion of Control Unit Port (CUP) support further enhances the MDS offering by allowing in-band management of the switch from FICON processors. This chapter includes the following sections: • FICON Overview, page 16-1 • FICON Configuration Requirements, page 16-6 • Initial Troubleshooting Checklist, page 16-7 • FICON Issues, page 16-9 FICON Overview The Cisco MDS 9000 Family supports the Fibre Channel, FICON, iSCSI, and FCIP capabilities within a single, high-availability platform. Fibre Channel and FICON are different FC4 protocols and their traffic are independent of each other. If required, devices using these protocols can be isolated using VSANs. The Cisco SAN-OS FICON feature supports high-availability, scalability, and SAN extension technologies including VSANs, IVR, FCIP, and PortChannels. Tip When you create a mixed environment, place all FICON devices in one VSAN (other than the default VSAN) and segregate the FCP switch ports in a separate VSAN (other than the default VSAN). This isolation ensures proper communication for all connected devices. You can implement FICON on the following switches: • Any switch in the Cisco MDS 9500 Series. • Any switch in the Cisco MDS 9200 Series (including the Cisco MDS 9222i Multiservice Modular Switch). • Cisco MDS 9134 Multilayer Fabric Switch. • MDS 9000 Family 18/4-Port Multiservice Module. Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05 16-1 Chapter 16 Troubleshooting FICON FICON Overview Send documentation comments to [email protected] Note The FICON feature is not supported on Cisco MDS 9120, 9124 or 9140 switches, the 32-port Fibre Channel switching module, Cisco Fabric Switch for HP c-Class BladeSystem or Cisco Fabric Switch for IBM BladeCenter.

  • Oracle's Storage Augments Mainframe Renaissance
    Oracle’s Storage Augments Mainframe Renaissance Mainframe Storage Solutions Remain Best in Class September 2010 Report by Fred Moore, President of Horison Information Strategies, Delivering Continuing Innovations in Mainframe Storage Th Early Mainframes - 1964 System/360 was announced by IBM in April 1964 and is generally considered the first mainframe computer. More than any other computer development effort, the System/360 family of processors enabled companies to affordably integrate all of their data processing applications into a single management information system. The term “360” was actually chosen to show the versatile nature of the computer, which could cover a “360-degree radius” of business applications. At the time, it defined the mainframe as a system that could perform multiple tasks at the same time on one machine and it was now possible to perform one million instructions per second (1 MIPS). The System/360 was also designed to be compatible through all models so that work performed o any model in the 360 series could be ported to any other model. The System/360 could process online, batch and databases at the same time in a multi-programming mode so that the system was literally tailored to the specific customer's jobs. Until the introduction of the System/360 architecture, which introduced many of today’s storage management concepts, accessing large amounts of data had been very time consuming. System/360 greatly improved data storage and retrieval capabilities while providing management with real-time decision-making capabilities for the first time. 1 Mainframes in Transition – 1980s The mainframe was the predominant computing platform from its introduction in the mid-1960s until the mid 1980s.
