Figure 14-11 shows the global cache coherency screen from Enterprise Manager (EM), which illustrates that with
three private interconnects, the latency is considerably low while maintaining high block transfers utilizing all three
private interconnects.

Table 14-4 is a compilation of the various tests performed using the old method (NIC bonding) and the new HAIP
option. The output generated and illustrated in Figure 14-12 indicates an almost close to perfect linear scalability.
These results are from a controlled test environment, and in real life scenarios some variations are possible. However,
the overall benefit of higher throughput compared to NIC bonding can be achieved using the HAIP feature.
