Installing and Configuring Interconnect, Storage, and Fibre Channel Hardware
For the most part, using interconnect, storage, and FC hardware does not differ markedly from noncampus cluster configurations.
The steps for installing Ethernet-based campus cluster interconnect hardware are very similar to those for noncampus clusters. Refer to Installing Ethernet Cluster Interconnect Hardware.
When installing the media converters, consult the documentation that came with them, including requirements for fiber connections.
The guidelines for installing virtual local area networks s interconnect networks are very similar to those for noncampus clusters. See Configuring VLANs as Private Interconnect Networks.
The steps for installing Sun StorEdge A5x00 and Sun StorEdge T3/T3+ arrays are very similar to those for noncampus clusters. For information about how to install a Sun StorEdge A5x00 array, see the Sun Cluster 3.1 With Sun StorEdge A5x00 Array Installation and Service Manual. For information about how to install a Sun StorEdge T3/T3+ array, see the Sun Cluster 3.1 With Sun StorEdge T3 or T3+ Array Partner-Group Configuration Installation and Service Manual and the Sun Cluster 3.1 With Sun StorEdge T3 or T3+ Array Single Controller Configuration Installation and Service Manual.
However, when installing Sun StorEdge A5x00 arrays at distances greater than 500m, install the Sun Long Wave GBICs as indicated in the Sun StorEdge Long Wave GBIC Interface Converter Guide. This manual also includes single-mode fiber specifications.
Campus clusters by using Sun StorEdge T3/T3+ arrays require FC switches to mediate between multimode and single-mode fibers. The steps for configuring the settings on the FC switches are very similar to those for noncampus clusters.
Cascaded-switch SAN setups have requirements that are distinct from those of noncascades setups, especially with regard to mirroring and zoning. For cascaded-switch SAN setup requirements, see the documentation that shipped with your switch hardware. For more information about how to use the FC switches in a campus cluster configuration, also see the documentation that shipped with your switch hardware.
Additional Campus Cluster Configuration Examples
Campus Cluster Configuration Examples showed three possible configurations for campus clustering: a two-room configuration that uses Sun StorEdge T3 partner groups for host-based mirroring, a two-room configuration that uses Sun StorEdge 9900 series storage devices for storage-based data replication, and a three-room configuration by using Sun StorEdge A5x00 arrays. While detailing all of the configurations possible in campus clustering is far beyond the scope of this document, the following illustrations depict some other variations on the setups previously shown.
The following are two-room examples:
Two-room campus cluster with a multipathing solution implemented (Figure A-4)
Two-room campus cluster without a multipathing solution implemented (Figure A-5)
Two-room cluster by using Sun StorEdge A5x00 disk arrays (Figure A-6)
The following are three-room examples:
Three-room campus cluster by using a StorEdge A5x00 with a multipathing solution implemented (Figure A-7)
Three-room campus cluster by using a StorEdge A5x00 without a multipathing solution implemented (Figure A-8)
Three-room campus cluster by using Sun StorEdge A5x00 disk arrays (Figure A-9)
Three-room campus cluster by using a server to replaces the storage array in the third room. (Figure A-10)
Three-room campus cluster by using StorEdge T3 arrays and FC switches. (Figure A-11)
Two-Room Examples
Figure A-1 depicted a two-room campus cluster by using Sun StorEdge T3 partner groups and four FC switches. Figure A-4 shows a similar setup with a multipathing solution implemented. The four switches are added to the cluster for greater redundancy and potentially better I/O throughput. This configuration could be implemented by using Sun StorEdge T3 partner groups or Sun StorEdge 9910/9960 arrays with Sun StorEdge Traffic Manager software installed.
For information on Sun StorEdge Traffic Manager software, see the Sun StorEdge Traffic Manager Installation and Configuration Guide at http://www.sun.com/products-n-solutions/hardware/docs/.
Figure A-4 Two-Room Campus Cluster With a Multipathing Solution Implemented

Figure A-5 is similar to Figure A-1, except that it does not have a multipathing solution implemented. This configuration could be implemented by using Sun StorEdge T3/T3+ arrays in single-controller configurations, rather than partner-groups.
Figure A-5 Two-Room Campus Cluster Without a Multipathing Solution Implemented

Figure A-6 depicts a two-room campus cluster by using Sun StorEdge A5x00s. Note the absence of switches.

Three-Room Examples
Sun Cluster supports several three-room campus cluster configurations.
Figure A-7, Figure A-8, and Figure A-9 show Sun StorEdge A5x00 disk arrays in the quorum room. The StorEdge A5x00 arrays do not require switches as the long-wave GBICS are already present in the A5x00 and should be present in the server's host bus adapters.
Figure A-7 is the same as Figure A-1, except that the quorum disk is separate and in a third room.
Figure A-7 Three-Room Campus Cluster With a Multipathing Solution Implemented

Like Figure A-5, Figure A-8 depicts a campus cluster without a multipathing solution implemented. However, in Figure A-8 the quorum disk is separate, in a third room.
Because the configurations in Figure A-7 and Figure A-8 use heterogeneous storage setups (Sun StorEdge T3/T3+ or Sun StorEdge 9910/9960 and Sun StorEdge A5x00 arrays), the host bus adapter types will be mixed. The Sun StorEdge A5x00 connects to the server by using a SOC+-based SBus host adapter, so the server must be SBus-based, meaning that the connection to the storage arrays must also be SBus-based. Therefore, the storage array connection must be via a Sun StorEdge SBus Dual FC Network Adapter.
Figure A-8 Three-Room Campus Cluster Without a Multipathing Solution Implemented

Figure A-9, like Figure A-6, depicts a campus cluster by using Sun StorEdge A5x00 arrays; however, in Figure A-9, the quorum disk is now separate and in its own room.
Figure A-9 Three-Room Campus Cluster (Sun StorEdge A5x00s)

Figure A-10 depicts a three-room campus cluster where the third room contains a server instead of a storage array. By including the third server in the configuration, you remove the need for a quorum device.
Figure A-10 Three-Room Campus Cluster (Third-room Server Replaces Storage Array)

Figure A-11 depicts a three-room campus cluster where the third room contains a StorEdge T3 and is connected to the other rooms through FC switches.
