2 Planning
Consider the following when planning a fabric:
 Devices
 Device Access
 Performance
 Feature Licensing
 Multiple Chassis Fabrics
 Switch Services
 Internet Protocol Support
 Security
 Fabric Management
Devices
When planning a fabric, consider the following:
 The number of devices and the anticipated demand. This will determine the
number of ports that are needed and the number of switches.
 The transmission speeds of your HBAs and SFPs. The SFP ports support
1-Gbps, 2-Gbps, and 4-Gbps transmission speeds depending on the SFP.
8-Gbps I/O blades also support 8-Gbps.
 The distribution of target and initiator devices. An F_Port supports a single
device. An FL_Port can support up to 126 devices in an arbitrated loop.
NOTE:
Setting an SFP port to 1-Gbps that has an 8-Gbps SFP transceiver will down
the port.
