Devices

When planning a fabric, consider the number of 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 optical transceivers, but the device host bus adapters you are using may not. Consider whether the device adapters use SFP transceivers or Gigabit Interface Converters (GBIC), and choose fiber optic cable accordingly. Use LC-type cable connectors for SFP transceivers and SC-type cable connectors for GBIC transceivers.

SANbox2 switches support only public devices. Consider the distribution of target and initiator devices. An F_Port supports a single public device. An FL_Port can support up to 126 public devices in an arbitrated loop.
