    Executive summary In todays IT organizations, the demands of rapid database implementations continue to escalate. Faster transaction processing speeds, capacity-based scaling, increased flexibility, high availability and business continuity are required to meet the needs of the 24/7 business.

    This Reference Architecture is intended to provide customers with the expected performance implications associated with deploying Oracle Real Application Clusters (RAC) 12c on HPE ProLiant DL380 Gen9 and HPE 3PAR StoreServ 8450 All Flash storage, and also demonstrate scaling from one to four server nodes while providing a highly available Oracle database. This while paper will help customers in planning to provide the appropriate level of performance and continue to meet the SLAs that are a key requirement for their business enterprises.

    Testing performed as part of this Reference Architecture establishes a baseline level of performance based on a Single-Instance version of the Oracle database. That baseline was then compared to 1, 2, 3 and 4-node Oracle RAC deployments. While Oracle RAC One Node performed at a level somewhat less than that of the Single-Instance deployment, the testing exhibited a near linear scaling effect when adding nodes to the cluster.

    Target audience: This Hewlett Packard Enterprise Reference Architecture (RA) is designed for IT professionals who use, program, manage, or administer large databases that require high performance. Specifically, this information is intended for those who evaluate, recommend, or design new and existing IT high performance architectures. Additionally, CIOs may be interested in this document as an aid to guide their organizations to determine when to implement Oracle RAC and the performance characteristics associated with that implementation.

    This RA describes testing completed in August 2016.

    Document purpose: The purpose of this document is to describe a Reference Architecture that organizations can utilize to plan for their deployment of Oracle RAC whether they are converting from an Oracle Single-Instance Database design model or adding servers to their existing Oracle RAC databases.

    Introduction Information Technology departments are under pressure to add value to the business, improve existing infrastructure, enable growth and reduce overhead. As Oracle database footprints grow, IT departments have to make a decision whether to grow their database infrastructure to a larger Single-Instance server, or whether to grow their database infrastructure horizontally using a number of cooperating servers in a clustered, Oracle RAC environmen
