IBM will debut Linux database cluster packages at this week's LinuxWorld conference in San Francisco. The DB2 Integrated Cluster Environment can scale up to 1,000 nodes, IBM says. The prepackaged, pretested systems reduce the time needed to install clustered database servers running on Linux. The packages include DB2 Universal Database and DB2 Express; IBM servers, including the xSeries and the new eServer 325 based on Advanced Micro Devices Inc.'s Opteron chip; Linux operating software from Red Hat Inc. or SuSE Linux AG; and IBM's Tivoli System Automation for Linux. Pricing starts at $8,700 for a two-node system.
