Investigate the applicability of 3-node disaster recovery

From Wikibon

IT organizations should not attempt to lead planning efforts for disaster recovery but instead must not only accept but demand business leadership in this critically important domain. IT organizations should, however, immediately begin investigating the three-node data center architecture as a technical approach to provide the IT architecture that may be required for DR and establish strong relationships with facilities and other internal groups that will ultimately have to assess the probability and consequences of having to respond to a major disruption in the business.
