Clustering & Teaming
4-38 GAM Client User’s Guide
Clustering & Teaming
In a clustered RAID environment, multiple controllers share the same back
end SCSI disk drives through a SCSI or Fibre channel cable(s). If the
controllers reside on different systems respectively, it is called clustering. A
clustering software manages the clustering configuration. If controllers
reside on the same system, it is called teaming. PATHpilot Pro manages the
task of teaming by allowing monitoring and manipulation of paths. GAM
provides the following information:
• Servers participating in the cluster configuration
• Controllers that are part of the cluster configuration
• Channels on each cluster that share backend disk drives
Select View->Cluster Map to open the Cluster Map Window (Figure 4-35).
Figure 4-35. Cluster Map
The Cluster Map dialog box displays a graphical backend cable
connection for the controller selected from the Cluster Controller list.
Channels on the cluster controllers connected by a colored line are
shared channels where disk drives are shared. Private channels are
shown without any connection. In Figure 4-35, four controllers are
connected by three shared cables. If these four controllers reside on
different controllers respectively, it is called four nodes clustering. To
show a server or IP address for each node, the four servers should be
