    Oracle Database Enterprise Edition White Paper

    Executive summary

    Customers require an open, scalable, tiered, highly available and high performance infrastructure to run their critical Oracle database systems. Their IT organizations must strive for better performance and increased efficiency in their Oracle infrastructure and Oracle database and storage administration operations. To achieve these goals, they need to:

    Reduce capital expenditures and operational expenditures by deploying an open, non-lock-in technology.

    Consolidate many Oracle databases (Oracle database versions 10gR1 to 11gR2 and Oracle 12c) and database workloads, including online transaction processing (OLTP) and Data Warehouse, to maximize the efficiency of the data center infrastructure.

    Deliver maximum performance while effectively utilizing the existing storage arrays and computing infrastructure for Oracle databases.

    Maintain high performance levels and provide predictable throughput to deliver the quality of service required in these Oracle mixed-workload environments.

    EMC proven high performance solution for Oracle Real Application Clusters (RAC) on EMC VNX is an open architecture that incorporates a choice of Intel servers with EMC server-side flash storage (EMC XtremSF) and EMC VNX storage arrays.

    The solution uses optimal servers to balance performance, scalability and Oracle license costs. The use of EMC Xtrem technologies, including XtremSF cards and EMC XtremCache software in the servers, provides distinct performance and operational advantages over equivalent systems that do not contain server-side flash technologies.

    To accelerate an Oracle RAC environment, XtremCache:

    Features an ultra-performance tier: XtremCache accelerates any application that benefits from low-latency, high bandwidth physical read I/O, meaning that:

    The most frequently accessed data resides on database server flash.

    The data is as close to the Oracle Database server CPU as any storage model will allow.

    Cooperates with Oracle Clusterware: Oracle Clusterware is the final authority on all node membership information in an Oracle RAC deployment.

    Offers optimized performance: VNX arrays do not need to handle read IOPS once the data is read into XtremCache, leaving more bandwidth for handling writes. EMC Fully Automated System Tiering (FAST) enables automatic data placement as data goes from hot to cooler usage.

    Improves performance with FAST Suite: Enabling the FAST Suite feature in VNX including FAST VP and FAST Cache improves the performance when the workload increases and the working set grows beyond the total capacity of the XtremCache.

    Business challenge

    Technology solution: open architecture components

    Delivers high performance levels: This solution delivers high performance for mixed workloads in Oracle database environments. The Key results and recommendations section provides details.

    Open standards benefits

    This solution is based on open standards. Advantages resulting from the open standards commitment include the following:

    A flash everywhere architecture, which produces the optimal use of flash from the Oracle database server to the EMC storage platform

    Mitigation of I/O bottlenecks to deliver maximum Oracle read performance, enabling the VNX to serve more I/Os for other applications

    Flexible adaptation to existing and future customer needs and open industry standards

    Lower capital investment and operational expense without the need to use a specific vendor

    Operational advantages

    EMC open architecture not only supports different releases of Oracle Database software (10g, 11g, and 12c), but it also allows different databases to run concurrently.

    Open architecture and flexible adaptation means that application modification is not required for database deployment for this solution. This lessens the potential impact to business operations and systemic data flow throughout the enterprise.

    The purpose of the solution is to build an EMC high performance solution for Oracle RAC on a VNX infrastructure based on an open architecture and demonstrate the following capabilities of the infrastructure:

    High performance and flexibility

    Low operational costs

    Reduced risk

    This white paper validates the performance of the solution and provides guidelines to build similar solutions.
