Dominican:
An outside consultant can provide technical and project management help but you cannot delegate the Disaster Recovery planning to the outside consultant. A very important part of the planning is making the decisions that trade off cost vs. time to recover and the consultant should not be the person doing this.
In the case of Dominican, relocating and/or separating the servers might make a small difference in the time it takes to recover but (in my opinion) not enough to make up for the expense. The server location issue is not as important as having the right off-site backups, testing recovery plans, and being able to contact and account for the people.
The Priory Campus is probably too close to be considered for use as a Disaster Recovery Site. http://www.computerworld.com/s/article/80262/U.S._regulators_issue_disaster_recovery_guidelines requries a minimum distance of 200 - 300 miles. However, these government regulations apply to financial exchanges that are important to the national economy. Dominican is not required to follow these regulations.
