In the performance test discussed in Chapter 8, comparing each application resided on its own array groups. The only resource shared by the application is the storage controller (cache, paths, etc.), and two ACP pairs (there are four ACP pairs total). The comparison is between the Hitachi Freedom Storage™ 7700E, representing all shared
