dunnhumby considered Teradata, IBM Netezza, and other solutions, and selected Oracle Exadata for its ability to sustain high performance and throughput even during concurrent queries. “We needed to see how the system performed when scaled to multiple concurrent queries, and Oracle Exadata’s throughput was much higher than competitive offerings,” said Chris Wones, director of data solutions, dunnhumby, USA.
dunnhumby began its Oracle Exadata implementation in September 2012 and went live in April 2013. It has installed four Oracle Exadata machine units in the United States and four in the United Kingdom. The company is using three of the four machines in each country as production environments and one machine in each country for development and testing. dunnhumby runs an active-active environment across its Oracle Exadata clusters to ensure high availability.
