3.1
Devices
When planning a fabric, consider the number of public devices and the anticipated
demand. This will determine the number of ports that are needed and in turn the
number of switches. Consider how many and what types of switches are needed.
The switch uses SFP transceivers in the 1-Gbps/2-Gbps ports, but the device host
bus adapters you are using may not. Consider whether the device adapters use
SFP or Gigabit Interface Converters (GBIC) transceivers, and choose fiber optic
cables accordingly. Use LC-type cable connectors for SFP transceivers and
SC-type cable connectors for GBIC transceivers. Also consider the transmission
speed compatibility of your devices, HBAs, switches, and SFPs.
Consider the distribution of targets and initiators. An F_Port supports a single
public device. An FL_Port can support up to 126 public devices in an arbitrated
loop.
