Additional Campus Cluster Configuration Examples

Language:

While detailing all of the configurations that are possible in campus clustering is beyond the scope of this document, the following illustrations depict variations on the configurations that were previously shown.

Three-room campus cluster with a multipathing solution implemented (Three-Room Campus Cluster With a Multipathing Solution Implemented)
Two-room campus cluster with a multipathing solution implemented (Two-Room Campus Cluster With a Multipathing Solution Implemented)
Two-room campus cluster without a multipathing solution implemented (Two-Room Campus Cluster Without a Multipathing Solution Implemented)

Figure 16 Three-Room Campus Cluster With a Multipathing Solution Implemented

image:Illustration: The preceding and following contexts describe the graphic.

Two-Room Campus Cluster With a Multipathing Solution Implemented shows a two-room campus cluster that uses partner pairs of storage devices and four FC switches, with a multipathing solution implemented. The four switches are added to the cluster for greater redundancy and potentially better I/O throughput.

For information about the Oracle Solaris I/O multipathing feature, see the Managing SAN Devices and Multipathing in Oracle Solaris 11.3.

Figure 17 Two-Room Campus Cluster With a Multipathing Solution Implemented

image:Illustration: The preceding context describes the graphic.

The configuration in the following figure could be implemented by using arrays in single-controller configurations, rather than partner groups.
