Dolphin SuperSockets have proven performance, robustness and fault resilience to scale business critical database performance with MySQL Cluster.
Capgemini UK plc ("Capgemini") has developed a nationwide GB seat reservation enquiry system based on MySQL Cluster and Dolphin Interconnect technology to meet challenging performance requirements in throughput and response times. The system is accessed from sales points, call centers and Internet applications and is capable of performing in excess of the 600 transactions per second required. The price/performance requirements could only be met through use of standard high volume server technology coupled with Dolphin's high performance interconnect. At application level, the solution was 58% faster and resulted in 35% more transactional throughput than with Gigabit Ethernet. When going live, the system was configured with two Dolphin adapters and double network interfaces in each server to provide fault resilience for this business critical application.

"We were looking for a cost-effective solution for our customers that could handle their tough requirements for both performance and fault resilience," said Roelof Kleinsmiede, senior technical architect at Capgemini, UK.  "MySQL Cluster and the Dolphin technology delivered on all of these.  We were also very happy with Dolphin's software and support -- they ported the library to PowerPC on short notice. Whenever we had a question, we got a mail reply back within minutes rather than hours."

Einar Rustad, Dolphin VP Business Development, said, "Dolphin SuperSockets brings high performance and fault resilient communication to any application using the Berkeley Sockets API. The software library utilizes Dolphin's unique interconnect technology features to provide the lowest latency and highest bandwidth sockets communication for databases combined with high availability features like instant fail-over and automatic rerouting. Dolphin has been working closely with the MySQL Cluster team to optimize the solution, outperforming any other alternative. It is very encouraging to see companies like Capgemini choosing innovative platforms for development of business critical solutions for their customers."

MySQL Cluster is a special high-end version of the world's most popular open source database -- specifically designed for fault-tolerant, mission-critical applications that need strict scalability and high-availability. It stores data in memory and utilizes a shared-nothing approach to clustering, enabling linear Scale-Out and high performance.

The Dolphin SuperSockets, library is specifically targeted at applications requiring efficient inter-process communication with high volumes of short transactions. With Dolphin SuperSockets, all applications communicating through TCP/UDP/IP protocols need no modifications to take full advantage of the Dolphin hardware, offering users a major improvement in performance and scalability. Dolphin products support major operating system platforms including Linux, Solaris and Windows
"Dolphin expects the market for database servers to be of vital interest for our company in the coming years," said Kåre Løchsen, Dolphin CEO. "The price/performance level that can be achieved through use of commodity servers being applied with our high-speed interconnect solutions will challenge the traditional large systems in more and more application areas in the time to come."

Bertrand Matthelié, director of EMEA marketing for MySQL AB, said, "MySQL is being used throughout the travel industry for these online 'Look-to-Book" reservation systems due to its high-performance, scalability and low TCO.  We appreciate Capgemini's trust in our open source database clustering software - as well as Dolphin's support and assistance in integrating our technologies to be able to meet the most demanding high volume enterprise applications."
