  • Faster Oracle Performance with IBM Flashsystem 2 Faster Oracle Performance with IBM Flashsystem
    IBM Systems and Technology Group May 2013 Thought Leadership White Paper Faster Oracle performance with IBM FlashSystem 2 Faster Oracle performance with IBM FlashSystem Executive summary The result is a massive performance gap, felt most painfully This whitepaper discusses methods for improving Oracle® by database servers, which typically carry out far more I/O database performance using flash storage to accelerate the most transactions than other systems. Super fast processors and resource-intensive data that slows performance across the massive amounts of bandwidth are often wasted as storage board. devices take several milliseconds just to access the requested data. To this end, it discusses methods for identifying I/O performance bottlenecks, and it points out components that are the best candidates for migration to a flash storage appliance. An in-depth explanation of flash technology and possible implementations are also included. The problem of I/O wait time Often, additional processing power alone will do little or nothing to improve Oracle performance. This is because the processor, no matter how fast, finds itself constantly waiting on mechanical storage devices for its data. While every other component in the “data chain” moves in terms of computation times and the raw speed of electricity through a circuit, hard drives move mechanically, relying on physical movement around a magnetic platter to access information. In the last 20 years, processor speeds have increased at a Figure 1: Comparing processor and storage performance improvements geometric rate. At the same time, however, conventional storage access times have only improved marginally (see Figure 1). IBM Systems and Technololgy Group 3 When servers wait on storage, users wait on servers.

  • IBM Power® Systems for SAS® Empowers Advanced Analytics Harry Seifert, Laurent Montaron, IBM Corporation
    Paper 4695-2020 IBM Power® Systems for SAS® Empowers Advanced Analytics Harry Seifert, Laurent Montaron, IBM Corporation ABSTRACT For over 40+ years of partnership between IBM and SAS®, clients have been benefiting from the added value brought by IBM’s infrastructure platforms to deploy SAS analytics, and now SAS Viya’s evolution of modern analytics. IBM Power® Systems and IBM Storage empower SAS environments with infrastructure that does not make tradeoffs among performance, cost, and reliability. The unified solution stack, comprising server, storage, and services, reduces the compute time, controls costs, and maximizes resilience of SAS environment with ultra-high bandwidth and highest availability. INTRODUCTION We will explore how to deploy SAS on IBM Power Systems platforms and unleash the full potential of the infrastructure, to reduce deployment risk, maximize flexibility and accelerate insights. We will start by reviewing IBM and SAS’s technology relationship and the current state of SAS products on IBM Power Systems. Then we will look at some of the infrastructure options to deploy SAS 9.4 on IBM Power Systems and IBM Storage, while maximizing resiliency & throughput by leveraging best practices. Next, we will look at SAS Viya, which introduces changes to the underlying infrastructure requirements while remaining able to be deployed alongside a traditional SAS 9.4 operation. We’ll explore the various deployment modes available. Finally, we’ll look at tuning practices and reference materials available for a deeper dive in deploying SAS on IBM platforms. SAS: 40 YEARS OF PARTNERSHIP WITH IBM IBM and SAS have been partners since the founding of SAS.

    Front cover IBM FlashSystem 9200 Product Guide Jon Herd Redpaper IBM FlashSystem 9200 Product Guide This IBM® Redbooks® Product Guide publication describes the IBM FlashSystem® 9200 solution, which is a comprehensive, all-flash, and NVMe-enabled enterprise storage solution that delivers the full capabilities of IBM FlashCore® technology. In addition, it provides a rich set of software-defined storage (SDS) features, including data reduction and de-duplication, dynamic tiering, thin-provisioning, snapshots, cloning, replication, data copy services, and IBM HyperSwap® for high availability (HA). Scale-out and scale-up configurations further enhance capacity and throughput for better availability. The success or failure of businesses often depend on how well they use their data assets for competitive advantage. Deeper insights from data require better information technology. As organizations modernize their IT infrastructure to boost innovation, they need a data storage system that can keep pace with highly virtualized environments, cloud computing, mobile and social systems of engagement, and in-depth and real-time analytics. Making the correct decision about storage investment is critical. Organizations must have enough storage performance and agility to innovate because they must implement cloud-based IT services, deploy a virtual desktop infrastructure (VDI), enhance fraud detection, and use new analytics capabilities. Concurrently, future storage investments must lower IT infrastructure costs while helping organizations derive the greatest possible value from their data assets. IBM FlashSystem storage solutions can accelerate the transformation of modern organizations into an IBM Cognitive Business®. IBM FlashSystem all-flash storage arrays are support the organization's active data sets. IBM FlashSystem solutions offer a broad range of industry-leading storage virtualization and data management features that can provide improved storage system performance, efficiency, and reliability.
