Supported Fabric Configurations
QuickLoop Attachment for Private Devices
NOTE The following configuration can be used when you are in the process of
migrating to fabric but your fabric environment is not yet fully
functional.
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 0-4 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 0-4 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.
