text: In systems with many relationships, a single slow relationship can cause delays for the 
  remaining relationships on the system. This setting isolates the potential relationship with 
  delays so that you can investigate the cause of these issues. When the maximum replication 
  delay is reached, the system generates an error message that identifies the relationship that 
  exceeded the maximum replication delay. 
  
  To avoid such incidents, consider deploying a SAN performance monitoring tool, such as IBM 
  Tivoli Storage Productivity Center, to continuously monitor the SAN components for error 
  conditions and performance problems. The use of such tool helps you detect potential issues 
  before they affect your environment. 
  
  When planning for use of the data replication services, consider the following aspects of the 
  solution: 
  
  (cid:2) Volumes and consistency groups for copy services 
  (cid:2) Copy services topology 
  (cid:2) Choice between Metro Mirror and Global Mirror 
  (cid:2) Connection type between clusters (FC, FCoE, IP) 
  (cid:2) Cluster configuration for copy services, including zoning 
  
  IBM explicitly tests products for interoperability with the Storwize V7000. For more information 
  about the current list of supported devices, see the IBM System Storage Interoperation 
  Center (SSIC) website.
