Deploying the DB2 pureScale Feature with EMC Symmetrix VMAX

In today's highly competitive marketplace, it is important to deploy a data processing architecture that not only meets your immediate tactical needs but also can grow and change to adapt to your future strategic requirements. In December 2009, IBM introduced the DB2 pureScale Feature for Enterprise Server Edition software (DB2 pureScale Feature). The DB2 pureScale Feature builds on familiar and proven design features from the IBM DB2 for z/OS database software (DB2 for z/OS), bringing the industry-leading technology and reliability of DB2 for z/OS to the open systems platform.

A key aspect of the IBM® DB2® pureScale® solution is related to the capabilities of the underlying storage. The storage must not only provide best-of-breed performance but must also possess best-of-breed availability characteristics. In addition, the DB2 pureScale Feature takes advantage of specific storage capabilities to enhance the solution. This paper takes you through the value proposition of deploying DB2 pureScale databases on EMC® Symmetrix® VMAX® storage arrays, demonstrating a solution that meets the needs of even the most demanding businesses.

The DB2 pureScale feature helps to meet the availability and capacity needs of your organization by providing the following:

  • Extreme capacity. The ability to scale out your system by easily adding additional server systems to your cluster.
  • Application transparency. The ability to use your existing applications with minimal or no changes.
  • Continuous availability. The inherent redundancy that an active-active architecture provides.
  • Reduced total cost of ownership (TCO). Savings through simplified deployment and management of advanced technology.

In this paper

  • DB2 pureScale Feature exploitation of storage
  • DB2 cluster services tiebreaker disk
  • Ultra-fast failover using SCSI-3 persistent reserve
  • Device drivers and storage protocols
  • Multipath I/O drivers
  • Supported storage subsystems
  • Configuring EMC Symmetrix VMAX for pureScale storage
  • Validation matrix
  • Advantages of using the DB2 pureScale Feature
  • Deploying the DB2 pureScale Feature on an EMC Symmetrix VMAX storage array
  • Validating the configuration of a DB2 pureScale deployment
  • Configuring multipath I/O with EMC Symmetrix VMAX in a pureScale environment
  • Configuring AIX MPIO for VMAX
  • Configuring the Device Mapper Multipath module on Linux operating systems
  • Enabling and testing SCSI-3 PR with Symmetrix EMC VMAX storage controllers
  • Appendix A. Storage provisioning in Symmetrix VMAX with Enginuity code 5874 and higher
  • Appendix B. List of references for more information
