3 Planning

This section describes how to plan for the iSR6142 router. This includes the

following considerations:

 Devices (see page 3-1)

 Device Access (see page 3-2)

 FC Performance (see page 3-2)

 iSCSI/Gigabit Ethernet Performance (see page 3-3)

 Performance Tuning (see page 3-4)

 Topology (see page 3-7)

 Fibre Channel Switch Ports and Zoning Requirements (see page 3-8)

 Multiple Routers (see page 3-8)

 Management (see page 3-9)

 Recovery (see page 3-9)

 Services (see page 3-10)

 Security (see page 3-10)

Devices

When planning to use the router, consider the number of devices and the

anticipated demand. This will determine the required number of ports and in turn

the number of routers.

The router uses SFP transceivers in the 1-Gbps/2-Gbps Fibre Channel (FC) ports,

but some Fibre Channel (FC) devices may not use the same transceivers.

Consider whether the FC device to be connected to the router uses SFP or gigabit

interface converters (GBIC) transceivers, and choose fiber optic cables

accordingly. Use LC-type cable connectors for small form-factor pluggable (SFP)

transceivers and SC-type cable connectors for GBIC transceivers. Also consider

the transmission speed compatibility of your devices, host bus adapters (HBAs),

switches, and SFPs.
