IBM POWER7 systems provide more flexibility, performance, scalability, and reliability for running Oracle Database software than Oracle's Exadata solution. POWER7 systems allow for custom configurations tailored to specific workloads, support more advanced storage technologies, have demonstrated leading performance benchmarks, can scale both vertically and horizontally as needed, and deliver industry-leading reliability through features such as dynamic sparing and error handling. In contrast, Exadata offers a rigid configuration that lacks customization and forces a one-size-fits-all approach that can result in overprovisioning and wasted resources.
