The text document uploaded to TUGRAZonline is identical to the present master's thesis.

Das in TUGRAZonline hochgeladene Textdokument ist mit der vorliegenden Masterarbeit identisch. Datum Unterschrift Abstract Speculative execution is a feature integrated into most modern CPUs. Although intro- duced as a way to enhance the performance of processors, the release of Spectre attacks showed that it is a significant security risk. Since CPUs from various vendors, includ- ing Intel, AMD, ARM, and IBM, implement speculative execution, all different kinds of devices are affected by Spectre attacks, for example, desktop PCs and smartphones. Spectre attacks exploit the branch prediction mechanisms of the CPU and then use a cache covert channel to leak secret data. Several attack variants have been discovered since the release, including Spectre-PHT which targets the Pattern History Table of the CPU.

IBM FlashSystem A9000 storage system uses the IBM FlashCore® technology to help realize higher capacity and improved response times over disk-based systems and other competing flash and solid-state drive (SSD)-based storage. FlashSystem A9000 offers world-class software features that are built with IBM Spectrum™ Accelerate. The extreme performance of IBM FlashCore technology with a grid architecture and comprehensive data reduction creates one powerful solution. Whether you are a service provider who requires highly efficient management or an enterprise that is implementing cloud on a budget, FlashSystem A9000 provides consistent and predictable microsecond response times and the simplicity that you need. As a cloud optimized solution, FlashSystem A9000 suits the requirements of public and private cloud providers who require features, such as inline data deduplication, multi-tenancy, and quality of service. It also uses powerful software-defined storage capabilities from IBM Spectrum Accelerate, such as Hyper-Scale technology, VMware, and storage container integration. FlashSystem A9000 is a modular system that consists of three grid controllers and a flash enclosure. An external view of the Model 425 is shown in Figure 1.

  • 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.
