  • Impact of the New Generation of X86 on the Server Market
    Impact of the New Generation of x86 on the Server Market Gartner RAS Core Research Note G002012320, George J. Weiss, Jeffrey Hewitt, 3 June 2010, R3598 07042011 Intel and OEMs have driven performance and reliability of the Intel Xeon 7500 processor series (code-named Nehalem-EX) to a level overlapping what Gartner judges to be about 80% of the RISC/Itanium function/feature set, but at a much lower price point. The result will cause increased server technology consolidation toward a bipolar distribution: x86-based platforms and one primary market-share-leading RISC technology (IBM Power), complementing the prevailing legacy of mainframes. Key Findings • A bipolar technology distribution of one strong RISC (Power) and x86 will drive at least 70% to 80% of the market’s total revenue, while other technologies subsist with minor single-digit revenue share; beyond this decade, a unipolar market will exist in which x86 technology becomes the standard, predominant server technology. • Unix has receded by $4 billion in the past three years. Migrations from Unix to Linux or Windows continue, according to Gartner client discussions. • Users continue to optimize costs (such as through virtualization, lower hardware costs, open-source software and cloud computing) primarily on x86. • Of the three non-x86 technologies, IBM’s has had a recent track record of sustained market share growth. Recommendations • Calculate an approximate x86 total cost of ownership (TCO) equivalence or line item cost analysis for comparison as if these applications were to be hosted on x86 for similar performance/availability, when considering Unix upgrades. • Make the comparison to an approximately equivalent x86 configuration when evaluating price quotes.

  • Magic Quadrant for Blade Servers
    Magic Quadrant for Blade Servers Gartner RAS Core Research Note G00207244, Andrew Butler, George J. Weiss, 17 January 2011, V3RA4 01202012 This Magic Quadrant for Blade Servers focuses on a market that is growing in complexity and sophistication, due to the emergence of related form factors, such as skinless servers, and the fast-growing interest in cloud computing, virtual input/output and fabrics. WHAT YOU NEED TO KNOW Blades represent an important stage in the evolution of servers as separate, discrete platforms give way to modular designs, and the boundaries between servers, storage and networking become increasingly blurred. This creates an increasing overlap of functionality between product categories that were previously more clearly delineated. These boundaries will be further tested as fabric-based computing becomes more prevalent, and all blade servers are examples of a fabric-enabled architecture, due to the switch-based backplane or midplane that they exploit. Blades represent a more proprietary investment, due to the lack of hardware form factor interoperability standards and the growing dependence on proprietary management tools and virtual input/output (I/O) solutions. Due to their modular nature, blades offer compelling operational benefits, such as improved cabling, rapid hardware provisioning, high compute density, energy-efficient design and increasing management automation. However, blades deliver few, if any, incremental application benefits, compared with their rack- and tower-based peers. Blades are not the only choice for modular deployment; rack-optimized servers deliver some modularity benefits, and skinless servers now represent an even more extreme class of high-density deployment. Because many vendors position their blade and skinless servers as part of a standard “modular server” portfolio, the nascent market status of skinless servers is reflected in this year’s blade server Magic Quadrant.

  • System on Fabrics Utilising Distributed Computing
    SYSTEM ON FABRICS UTILISING DISTRIBUTED COMPUTING by Partheepan Kandaswamy A Doctoral Thesis submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University June 2018 © by Partheepan Kandaswamy To my parents Shanthi and Kandaswamy ii ABSTRACT The main vision of wearable computing is to make electronic systems an important part of everyday clothing in the future which will serve as intelligent personal assistants. Wearable devices have the potential to be wearable computers and not mere input/output devices for the human body. The present thesis focuses on introducing a new wearable computing paradigm, where the processing elements are closely coupled with the sensors that are distributed using Instruction Systolic Array (ISA) architecture. The thesis describes a novel, multiple sensor, multiple processor system architecture prototype based on the Instruction Systolic Array paradigm for distributed computing on fabrics. The thesis introduces new programming model to implement the distributed computer on fabrics. The implementation of the concept has been validated using parallel algorithms. A real-time shape sensing and reconstruction application has been implemented on this architecture and has demonstrated a physical design for a wearable system based on the ISA concept constructed from off-the-shelf microcontrollers and sensors. Results demonstrate that the real time application executes on the prototype ISA implementation thus confirming the viability of the proposed architecture for fabric- resident computing devices. iii ACKNOWLEDGEMENTS I would like to thank my supervisors Dr. James Flint and Dr. Vassilios Chouliaras for their continuous support, guidance, exceptional advice and shared knowledge throughout my PhD.

    White Paper The Federal Perspective Ethernet Fabrics for the Cloud: “...use cloud- Setting the Stage for the Next-Generation based solutions Data Center whenever a An IDC White Paper by Lucinda Borovick, March 2011 In late 2010, the U.S. federal government announced its “Cloud First” policy. It requires secure, reliable, federal agencies to use cloud-based solutions “whenever a secure, reliable, cost- cost-effective effective cloud option exists.” Cloud computing provides highly reliable, scalable resources quickly, addressing a cloud option number of issues impacting the current government IT environment. However, today’s traditional Ethernet networks dominate existing data centers, and employ inefficient exists.” architectures that can be both complex to manage and costly to operate. Why Ethernet Fabrics? This white paper contends that next-generation data centers should employ an Ethernet fabric architecture. Specifically, it defines an Ethernet fabric as “a bigger, flatter network that preserves the low cost and simplicity of Ethernet, requires no reconfiguration or change in port configurations when resources move, and uses all paths available through the data center(s) for the most efficient transport of virtual machines (VMs) and their data.” The white paper explains in detail how Ethernet fabrics can better support the demands of the cloud and the IT resource demands of enterprises, which are remarkably similar in many ways to the needs of government agencies. Ethernet fabrics are: • Simpler to build and manage • Far more flexible
