Fabric security
Fabric management
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 and optical transceivers in the 1Gbps/2Gbps 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.
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.
