Finally, an eight-node system in IP partnership with a four-node system over dual inter-site  links is depicted in Figure 6-34. Figure 6-34 shows an eight-node System A in Site A and a four-node System B in Site B.  Because a maximum of two I/O groups in IP partnership is supported in a system, although  there are four I/O groups (eight nodes), nodes from only two I/O groups’ are configured with  remote copy port groups in System A. The remaining or all of the I/O groups can be  configured to be remote copy partnerships over FC.  In this configuration, there are two links and two I/O groups that are configured with remote  copy port groups 1 and 2. However, path selection logic is managed by an internal algorithm.  Therefore, this configuration depends on the pathing algorithm to decide which of the nodes  actively participate in IP partnership. Even if Node A5 and Node A6 are configured with  remote copy port groups properly, active IP partnership traffic on both of the links can be  driven from Node A1 and Node A2 only.
