A processor that supports a 64-bit address space may provide access to in-memory databases that range from tens of Gigabytes to thousands of Terabytes. In contrast, traditional 32-bit processors most often only address a maximum of 4 GB. Multiple databases that required large amounts of memory and previously had to be distributed across several machines can now be consolidated onto fewer machines, taking advantage of the larger addressable linear address space. Key database software available for Itanium 2 systems include: IBM DB2® Universal Database™ 8.1 (both Linux and Windows versions) Microsoft SQL Server 2000 Oracle 9i Database (Linux/Windows) IBM DB2 Universal Database The DB2 Universal Database offers increased performance, reliability, and scalability on Windows and Linux platforms by exploiting the IA-64 servers built around the Itanium Processor Family of chips from Intel. The 64-bit version of DB2 delivers significantly higher levels of performance and reliability by exploiting the capabilities of the new systems. As the adoption of IA-64 architecture continues to move forward with most major server system OEMs using Windows and Linux operating systems, IBM DB2 Universal Database leads the software industry in providing business database application content to the IA-64 server platform. IBM DB2 Universal Database is currently enabling the most robust and varied database software application performance on the IA-64 architecture. By investing in IBM DB2 Universal Database application software designed for the IA-64 architecture, starting with the Itanium microprocessor, companies will be assured of having a solid foundation for their electronic business far into the future. Client/server configurations supported in this release are: 64-bit client to 64-bit DB2 UDB engine 64-bit client to 64-bit DB2 Connect™ gateway to DRDA® host 64-bit DB2 Connect Personal Edition to DRDA host 2.7.2 Business logic More and more enterprise applications such as ERP, SCM, CRM, and BI are released or announced to be released on a 64-bit platform. Such applications process large amounts of data and the large flat memory model means that this 48 IBM xSeries 455 Planning and Installation Guide Eserver
