Jean Bozman, research vice president for IDCs worldwide server group, said in a statement that Linux server revenues and unit shipments have accelerated in recent quarters, with Linux servers posting a 49.8 percent growth in revenue for the third quarter of 2003 compared with the second quarter. HP will also announce on Thursday new enterprise customers like Video Monitoring Systems, which is running HP ProLiant servers for its always-on environment. That Linux solution was "substantially less expensive than the Sun Solaris platform and delivered higher quality and far better performance than the Dell systems we previously used in our infrastructure," said Gerry Louw, chief information officer at VMS.In addition, HP will unveil several new Linux reference architectures, including commercial Linux reference architectures based on Oracle Database/9iRAC and BEA WebLogic Server and an open-source reference infrastructure architecture based on open-source software from MySQL, JBoss, Apache and OpenLDAP.The Linux reference architectures are being deployed on industry-standard HP ProLiant servers and will be deployed later on HP Integrity servers. "These solutions are tailored to enterprise customers migrating from Solaris, AIX and Tru64 to save them time and money," Fink said. HP will also announce updates to its Linux notebooks. The new HP Compaq t5300 and t5500 thin clients, priced at $299 and $349, respectively, feature Transmeta central processing units and high-resolution ATI Rage XC video. They come standard with a three-year limited hardware warranty, the company said.
