Benchmarking for Consolidation

  • Bert Scalzo


In this chapter we’re going to review benchmarking considerations for when you are testing scenarios in order to consolidate database instances. Database consolidation occurs when you attempt to reduce the total number of database licenses in order to reduce costs. With the rising cost of database licenses and the business considering a database as just a commodity, building-block object required for an application, your management might be required to undertake consolidation efforts. Moreover with today’s servers being so powerful, with multi-core CPUs and lots of cheap memory, we no longer must intentionally segregate databases using the traditional “silo” approach of one database per server. DBAs can now realistically look to co-locate all the data from multiple databases instances under a single database instance. Sometimes such efforts may coincide with a major database version upgrade or a licensing “true up” effort. One thing is for sure, with all the “database sprawl” that has occurred over the past 20 years, we all have more database instances than anyone could have reasonably imagined. So database consolidation efforts are more common than you might think.
