560 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
– If the Node A1 in System A or the Node B2 in System B were to encounter some failure 
in the system, IP partnerships discovery is triggered and it continues servicing the I/O 
from the failover port. 
– The discovery mechanism that is triggered because of failover might introduce a delay 
wherein the partnerships momentarily change to the Not_Present state and then 
recover. 
– The bandwidth of the single  link is used completely. 
/SM590000Eight-node system in IP partnership with four-node system over single inter-site link, as 
shown in Figure 11-101 (configuration 4).
Figure 11-101   Multinode systems single inter-site link with only one remote copy port group
As shown in Figure 11-101, there is an eight-node system (System A in Site A) and a 
four-node system (System B in Site B). A single remote copy port group 1 is configured on 
nodes A1, A2, A5, and A6 on System A at Site A. Similarly, a single remote copy port group 1 
is configured on nodes B1, B2, B3, and B4 on System B.
