Chapter 3. Implementing the INRANGE FC/9000 Fibre Channel Director 263
To do this, select the specific director in the navigation tree and then click the
Ports tab. After scrolling down we see the used ports with our given names, the
WWN of the attached ports, and then the zone these ports belong to as shown in
Figure 3-76.
Figure 3-76 IN-VSN: Director Port View showing the port to zone relationship
We now have two zones defined in a fabric consisting of one director.
Since both zones are saved and all specified external ports are actually attached
and online, we can start I/O between these servers and our ESS.
3.5 Cascading of directors
To further increase the amount of available FC ports, we can connect multiple
INRANGE directors using FC links. This kind of FC link will be automatically
discovered. This link is widely called an Inter-Switch Link (ISL).
The process of connecting directors using ISLs is known as cascading.
