2 PlanningDevicesThis chapter describes how to plan for the iSR6200 router. The following sectionsdescribe the devices and services you need to consider when planning to use theiSR6200 router:• “Devices” on page 2-1• “Device Access” on page 2-1• “Fibre Channel Switches Required for VPGroups” on page 2-2• “Fibre Channel Performance” on page 2-2• “iSCSI Performance” on page 2-3• “Performance Tuning” on page 2-4• “High Availability” on page 2-7• “Management” on page 2-7• “Recovery” on page 2-7• “Services” on page 2-8• “Security” on page 2-8When planning router use, consider the number of devices and the anticipateddemand. This determines the number of ports required and, in turn, the number ofrouters.The router uses SFP transceivers in the 8Gbps Fibre Channel (FC) ports, butsome Fibre Channel devices may not use the same transceivers. Considerwhether the Fibre Channel device you want to connect the router to uses SFP orgigabit interface converters (GBIC) transceivers, and choose fibre optic cablesaccordingly. Use LC-type cable connectors for SFP transceivers and SC-typecable connectors for GBIC transceivers. Also consider the transmission speedcompatibility of your devices, adapters, switches, and SFPs.Device AccessConsider device access needs within the Fibre Channel and iSCSI SANs.Controlling access to Fibre Channel device LUNs requires mapping FibreChannel device LUNs to specific iSCSI initiators. You may map LUNs to morethan one initiator. Giving multiple initiators access to a LUN requires accessmanagement.ISR651101-00 G 2-1
