MySQL AB & Red Hat Expand Partnership; Will Offer Optimized 'Scale Out' Solutions for Enterprise Customers.

SANTA CLARA, Calif. -- Open Source Leaders Collaborate on Technical Support and Clustering Solutions

MySQL AB, developer of the world's most popular open source database, today announced that it has strengthened its partnership with Red Hat, Inc. (NASDAQ: RHAT), the world's leading provider of open source solutions to the enterprise.

In keynotes at this week's MySQL User Conference, senior executives from the two companies pledged to work together to provide their common customers with better products and services for implementing high-demand database applications using an increasingly popular, more affordable and effective IT architecture called "Scale-out".

Marten Mickos, CEO of MySQL AB, said, "Compared to traditional "Scale-Up" methods using expensive hardware and proprietary software, the open source LAMP stack is well-suited for driving high-volume Web Sites, Data Warehouses and other business applications - leveraging low-cost, commodity hardware. As two of the leading proponents of the LAMP software stack, Red Hat and MySQL will support our customers with significant new joint initiatives."

Michael Tiemann, Vice President of Open Source Affairs at Red Hat, said, "MySQL and Red Hat are clear leaders in the open source software arena. Our companies share many customers in common, so it is natural to step up our collaboration to deliver more integrated, reliable and affordable solutions to the market."

MySQL & Red Hat Partnership

The expanded relationship includes plans for the companies to work together on a number of joint initiatives, including:

--Red Hat and MySQL have already started to deliver integrated, collaborative technical support to customers using MySQL on Red Hat Enterprise Linux. Each of the companies' technical support teams have implemented common processes to jointly support and resolve complex customer issues through TSANet, the industry standard network for collaborative support.

--MySQL and Red Hat plan to test the MySQL database with Red Hat's Cluster Suite and Global File System (GFS). Red Hat GFS allows a cluster of MySQL servers to simultaneously read and write data to a single shared file system on a SAN, achieving high performance and reducing the complexity and overhead of managing redundant data copies. With Red Hat Cluster Suite and GFS, MySQL customers can get a highly available clustered database solution based on all open source technologies.
