text: – 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. 
  
  (cid:2) Eight-node system in IP partnership with four-node system over single inter-site link, as 
  shown in Figure 11-101 (configuration 4).
