Clustering Support; Inventory Checklist - IBM TotalStorage DS4100 Installation, User's, And Maintenance Manual

Clustering support

Clustering is a means of sharing array groups among controllers to provide
redundancy of controllers and servers. This redundancy is important if a hardware
component fails. If a hardware component failure occurs in a cluster, another server
takes ownership of the array group.
Clustering requires software specific to your operating system. For more information
about clustering, go to the following Web site:
