This is true whether you are running in a virtualized environment or in a bare metal configuration. Regardless of what type of database workload you may have to deal with, and irrespective of how well designed and optimized your databases are, the characteristics and performance of your database hardware and storage subsystem are extremely important. Even the most well-designed and carefully tuned database application can be crippled by poorly chosen or inadequate hardware. This is not to say that hardware can solve all performance or scalability problems. A frequently executed, expensive query on an extremely large dataset can quickly overwhelm even the best hardware and storage subsystem.
