- For many organizations, the last few years have marked an increase in the number of applications used to facilitate business processes. This increase resulted in SQL Server database sprawl that became a drain on resources such as licensing and maintenance costs, as well as data center space requirements.
- Organizations turn to database consolidation as a means of reducing database sprawl; however, a database consolidation project can seem daunting and risky without a clear strategic roadmap.
Our Advice
Critical Insight
- In order to choose the appropriate consolidation model, IT departments should identify their consolidation goals and priorities such as manageability, high availability, and resource management. Based on a thorough evaluation, organizations should choose from the three primary consolidation models: database consolidation, instance consolidation, and virtualization.
- Recent releases of SQL Server have a proven track record of being reliable platforms for consolidation. Info-Tech recommends SQL Server 2008 R2 as a minimum for consolidation. If you are choosing to upgrade to the new 2012 version, review your requirements to choose the appropriate edition and licensing option.
- Info-Tech’s research indicates that the most important phase in the implementation process is the planning phase, particularly profiling candidates for consolidation. To identify the most appropriate candidates for migration, IT needs to perform sophisticated workflow modeling and hardware capacity planning. Test out your planning during a pilot before you promote the project to the production environment.
