The popular DB2 best practices paper DB2 databases and the IBM General Parallel File System is now updated and includes DB2 V10.1 support.
The examples in this paper are based on DB2 V10 fix pack 2 and GPFS 22.214.171.124 efix13 installed on AIX 6.1 TL6 SP5 but can be extended to more recent versions and other supported platforms. All versions of GPFS are supported with DB2 for Linux, UNIX, and Windows, however, the latest supported fix packs are recommended to ensure the best quality experience.
Technical paper summary:
In today’s highly competitive marketplace, it is important to deploy a data processing architecture that not only meets your immediate tactical needs, but that also provides the flexibility to grow and change to adapt to your future strategic requirements. To help reduce management costs, add flexibility, and simplify the storage management of your DB2® for Linux®, UNIX®, and Windows® installation, you need to choose a file system that is designed to provide a dynamic and scalable platform. The IBM® General Parallel File System™ (GPFS™) is a powerful platform on which to build this type of relational database architecture. This paper describes why GPFS is the right file system to use with DB2 databases by outlining the benefits and providing best practices for deploying GPFS with DB2 software. In addition, a section has been added to this paper to describe the DB2 pureScale feature, and how it configures and uses GPFS.
