SPARC: Two-Room Examples

Figure 7–7 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. 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 about Traffic Manager software, see the Sun StorEdge Traffic Manager Installation and Configuration Guide at http://www.sun.com/products-n-solutions/hardware/docs/.

The configuration in Figure 7–8 could be implemented by using Sun StorEdge T3 or T3+ arrays in single-controller configurations, rather than partner groups.

Figure 7–9 depicts a two-room campus cluster that uses Sun StorEdge A5x00s. Note the absence of switches.
