Planning
Consider the following when planning a fabric:
Devices
Device Access
Performance
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 transceivers, 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.
