Supported Fabric Configurations
Chapter 1 13
In a private loop environment, a QuickLoop configuration can allow
private hosts with a Tachyon adapter attached to a QL_Port to access
private devices on the loop by using the switch as a hub.
Figure 1-4 shows that Tachyon Host 1 is a private host which has access
to the private target devices connected to a QuickLoop port. TL Host 2, a
public host connected to a fabric port, also has access to the private
devices and any future public devices.
Figure 1-4 QuickLoop Attachment for Private Devices
For Tachlite hosts:
• Public hosts/devices cannot exist on a QL loop.
• Private QL hosts cannot connect to fabric devices.
• Public hosts connected to a QuickLoop port will behave as private
hosts and therefore is not recommended or supported.
Public Loop
A public loop is an arbitrated loop where at least one of the ports on the
loop is a switch port (FL_Port), which allows hosts or devices on the loop
to communicate with hosts or devices attached to other FL_Ports.
