LUN Configuration and Security Manager XP user guide for the XP128/XP1024 21

If you want to use a LUSE volume as a command device, you must specify only the first LU as the command

device.

Fibre Channel port attributes

In Fibre Channel environments, you must configure the Fibre Channel topology and set addresses for the

Fibre Channel ports. You can enhance system performance by adjusting the data transfer speed at the

Fibre Channel ports and changing the channel adapter mode.

Fibre Channel topologies

Fibre Channel provides the following topologies:

• Fabric: Uses a fabric switch to connect a large number of devices. Each device has the full bandwidth

of 100 MB/sec.

• FC-AL (Fibre Channel-Arbitrated Loop): A shared-bandwidth topology that can connect up to 126

devices (AL ports).

• Point-to-point: A simple Fibre Channel topology in which two devices are connected directly.

When configuring the disk array, use LUN Manager to specify whether the hosts and the disk array are

connected by a fabric switch. Also, you must specify FC-AL or point-to-point in the LUN Manager pane. The

default is FC-AL.

If you are using a fabric switch, consult the switch’s documentation to learn whether FC-AL or point-to-point

should be used. Some fabric switches require that you specify point-to-point to get the system running.

Arbitrated loop physical addresses

You will need to set addresses for Fibre Channel ports. When addressing Fibre Channel ports, you can use

AL-PA (arbitrated loop physical address) or loop IDs as the addresses (see Table 4).
