  • As every human being, company, organization, city, nation, natural system, and man-made system is becoming interconnected, instrumented, and literally made more intelligent. In this new world, we believe there are 3 questions to be considered:
    How can we take advantage of the wealth of information available from our new smarter things to make more intelligent choices? – New Intelligence
    How can we work smarter supported by flexible and dynamic processes modeled for the new way people buy, live & work – Smart Work
    How do we align our goals and behaviors with our new responsibilities, so that caring for our planet and its people is no longer perceived as generosity or sacrifice? - Green & Beyond
    How do we create an infrastructure that drives down cost, is intelligent and secure, and is just as dynamic as today’s business climate? – Dynamic Infrastructure
    Let’s discuss each of these in more detail. Why are they important? What are the pressures we face? Where can we look for solutions? How have enterprises already been working on smart solutions to their problems?
    New Intelligence
    Volume of Digital Data: The data explosion, of course, but also shifts in the nature of data. Once virtually all the information available to be "processed" was authored by someone. Now that kind of data is being overwhelmed by machine-generated data – spewing out of sensors, RFID, meters, microphones, surveillance systems, GPS systems and all manner of animate and inanimate objects.
    By 2010, the amount of digital information will grow to 988 Exabytes (equivalent to a stack of books from the sun to Pluto and back)
    Every day, 15 Petabytes of new information are being generated. This 8 times more than the information in all U.S. libraries
    The number of emails sent every day is estimated to be over 200 billion
    By 2010, the codified information base of the world is expected to double every 11 hours
    Variety of Information (diversity and heterogeneity): With this expansion of the sources of information comes large variance in the complexion of the available data -- very noisy, lots of errors -- and no time to cleanse it in a world of real-time decision making.
    80% of new data growth is unstructured content, generated largely by email, with increasing contribution by documents, images, and video and audio
    38% of email archiving decisions receive input from a C-level executive and 23% from legal/compliance professional
    The average car will have 100 million lines of code by 2010; the Airbus A380 alone contains over 1 billion lines of code
    Velocity of Decision Making: This is about optimizing the speed of insight generated as well as confidence that the decisions and actions taken will yield the best outcomes based on more proactive, planning around the management and use of information sources, and creating far more advanced predictive capabilities:
    Every week, the average information worker spends 14.5 hours reading & answering e-mail, 13.3 hours creating documents, 9.6 hours searching for information, 9.5 hours analyzing information
    For every 1,000 knowledge workers, $5.7 million is lost annually in time wasted reformatting information between applications.
    Not finding the right information costs an additional $5.3 million per year
    An Institute for Business Value Agile CFO Study in 2007 indicated that only 9% of senior finance executives believe they excel at gathering, interpreting & conveying information to senior management
    42% of managers say they inadvertently use the wrong information at least once per week
    Finally, shifts in the nature of what we can analyze: Traditionally, that's been the analysis of a standalone business process or sub-processes, or activities like airline crew scheduling. More and more, enterprises and governments -- as well as biologists, life scientists and environmentalists -- will have to take a broader, systems-based approach to what they examine and attempt to optimize. So crew scheduling, combined with weather patterns, combined with fuel prices, combined with marketing promotions and the status of labor negotiations, as one example; or the ability to tap into the collective intelligence of people across the value chain through social media and associated Web 2.0-3/0 technologies..
    Business intelligence is rated as the top IT spending category with 80% of C-level execs respondents rating it as high or medium priority
    Stream Computing and Event Processing capabilities are enabling the consumption and analysis of extreme volumes, speeds, and complexity of event scenarios real time (events generated from water streams, applications, news feeds, services; with technology able to analyze 5 million events per second).
    Smart Work
    A whole host of rapidly accelerating changes are unfolding: mergers of hundred year old companies, creation of new industries and the demise of others, the emergence of new economies, the opening of long isolated markets, the imposition of new government regulations and the relaxation of others, and so on. Organizations are driven to change and become more dynamic by these identified evolving forces:
    Economic Pressures: The emergence of a global economy is applying pressure on businesses to reduce costs and build better visibility into their business processes to mitigate risk and optimize profit.
    Global Competition: The emergence of a global economy is moving businesses to create more responsive processes to achieve improved agility within a worldwide competitive marketplace
    The Demanding Consumer: The expectations of customers and employees have never been higher, requiring businesses to supply a personalized and responsive environment. Such expectations for a personalized, custom, user experience are driving requirements back to the business and service provider to deliver innovative new services anytime, anywhere.
    Emergence of New Technology: New technologies like Cloud, Web 2.0 and pervasive digitally connected objects are empowering the business user and driving the convergence of business and IT and blurring the lines between companies, business partners and customers!
     
    In this fast paced, opportunistic and at times volatile environment, organizations need to be dynamic, resilient and efficient in how they build, assemble, reassemble, loosely couple, and link resources in the organization. Static, rigid, monolithic, and fragile will be the descriptors of the organizations that get left behind.
    Dynamic Infrastructure
    Multiple forces are driving a transformation of business and government of all sizes
    Business innovation can drive competitive advantage, but wreck havoc with existing IT infrastructures.
    98% of CEOs expect their business models to change, while a rapidly growing percentage recognizes they lack the ability to handle that change effectively
    New technologies, like Web 2.0, petaflop super computers, cloud computing
    Enterprises report that IT operational overhead = up to 70% of IT budget and growing
    The thrust of the discussion around dynamic infrastructure will center on three benefits: reducing costs, improving service and managing risk.
    Reducing cost
    Dramatically improve the total cost of both the underlying IT infrastructure and management costs associated with the need to speed delivery of IT services as well as managing the growing convergence of intelligent, instrumented business and IT assets - while successfully addressing mounting economic pressures, shifting consumer demands, service delivery expectations and the emergence of new technology.
    Improving Service
    Respond quickly and flexibly to business opportunities and customer demands with a superior business-driven service model that provides visibility, control and automation of the underlying business and IT infrastructure; align physical and IT assets to the business to enable rapid, agile response to changing business circumstances.
    Managing Risk
    Instill trust with key constituents and experience improved service reliability, respond effectively to regulatory and compliance requirements, and adapt quickly to changing conditions with the peace of mind that the business and IT infrastructure is secure and resilient, including the extended infrastructure created by “smart” and mobile devices, external networks, supply chains and explosion of data.
    Green & Beyond
    Businesses have been at the center of the converging pressure to go green… The public is demanding greener practices and is putting pressure on the government to introduce tougher regulations. The customers are resisting business attempts to pass on energy induced price hikes and are demanding greener products and policies. The environment is resonating as a critical issue affecting shareholder value across geographies. And the governments are creating tough new regulatory standards to control energy use and carbon emissions, or at least threatening to do so if businesses do not act first.
    Private enterprises, public organizations, communities, regions and entire industries are faced with how to develop strategies and solutions for becoming more energy and environmentally responsible that also generates new revenue opportunities and lower costs and risk.
    Intelligent energy and carbon management improvements are about adding intelligence to passive or “dumb” systems to create “smart systems” that are dramatically more efficient and reliable and therefore enabled to save energy and resources. Intelligent Utility Networks, Transportation Systems, and Oilfields all become more efficient. These are real solutions, available today, that harness and leverage the power of built-in intelligence to:
    •improve energy management
    •make our energy have less impact to the environment and be more reliable
    •reduce traffic congestion and associated greenhouse gas emissions
    •reduce energy demand
    Energy demand doubling● IT unable to keep pace
    99% of installed base of volume servers is inefficient today
    On average● only 3 out of 100 units are used for productive computing
    Only 28% respondents to IBM benchmarking tool report they know the energy consumption of IT
    e-waste cannot be ignored – 1 billion computers potential scrap by 2010
  • Consider how much energy we waste.
    According to published reports, the losses of electrical energy because grid systems are not “smart” range as high as 40 to 70 percent around the world.
    In distributed computing environments 85% of computing capacity sits idle. In six years, the power consumption of a server has risen from 8 watts to more than 100 watts per $1,000 worth of technology. On average, for every 100 units of energy piped into a data center, only 3 units are used for actual computing. More than half goes to cooling the servers.
    And, of course, consider the crisis in our financial markets.
    The current crisis will be analyzed for decades, but one thing is already clear: Financial institutions spread risk but weren't able to track risk – and that uncertainty, that lack of knowing with precision, undermined confidence.
  • Green represents unannounced products
    Auto HA solutions are Virtualization Engine-based offering for rapid provisioning and reprovisioning of server resources. Expected VE announce is May 2004
    Investment protection is the name of the game for BladeCenter.
    IBM will offer a full portfolio of BladeCenter based offerings. 64-bit blades, NEBS-compliant platforms, InfiniBand and iSCSI are all on the technology roadmaps.
    This is not a disclosure chart, and does not speak to the individual offerings, it is merely a guideline to what IBM thinks are appropriate technologies for the blade marketplace.

    4 times the cores (16 vs 4)**
    ** Statement refers to the maximum size of a logical partition or virtual machine in terms of CPUs. VMware Infrastructure 3 Enterprise supports a maximum of 4 virtual CPUs per virtual machine (source: VMware Infrastructure 3 Online Library, section “Virtual Machine Maximums” at http://pubs.vmware.com/vi301/config_max/config_max.1.2.html. The IBM System p 570 supports up to 16 CPUs per Logical Partition.
    10 times memory/per core (48 vs 4)***
    *** Statement refers to the maximum amount of memory supported in a virtual machine. VMware supports a maximum of 4 CPUs and 16 GB of RAM per virtual machine (source: http://pubs.vmware.com/vi301/config_max/config_max.1.2.html) . This translates to a total of 4 GB of RAM per CPU. IBM System p 570 supports up to the full memory and CPU configuration of the system for LPARs, which translates to 16 CPUs and 768GB of RAM. Thus, the p570 supports up to 48GB of RAM per core.
    Reduce impact of planned outages
    Relocate workloads to enable growth
    Provision new technology with no disruption to service
    Save energy by moving workloads off underutilized servers
  • This is a good overview slide to see how each of the DS storage systems are positioned.
    Starting with the DS3000 series. This is affordable entry-level storage platform designed for the small to medium business as well as departmental and remote office customers seeking cost-effective, reliable and simple storage. The DS3000 supports SAS, iSCSI or FC host connectivity with support for up to 48 SAS and/or SATA drives.
    We then continue to scale upward with the DS4000 and DS5000 series of storage systems. The DS4000 and DS5000 are fully-featured performance-driven midrange and enterprise storage designed for wide-ranging open systems environments. Ideally suited for compute-intensive applications and consolidation, the DS4000 and DS5000 series includes robust management software designed for the advanced storage administrator. This series also supports FC host connectivity with support up to 256 FC and/or SATA drives
  • And we will quickly gloss over this slide as I would like to suggest printing it out and getting it out when you are discussing and suggesting the DS series to your customers.
    Some of the key items your customer is looking for are listed in the left column and includes IOPs and megabytes performance, scalability, consolidation size, and replication features offered.
    And as an example, if my customer is looking for good scalability for their midrange environment, but large block performance that we know to be Megabytes per second is not critical, we may suggest the DS4800. However, if you have a smaller company in which replication features such as mirroring is not important but cost is, we would suggest the DS3000 series of arrays.

    4. 4. 4 En 6 años el consumo de energía de un server ha crecido de 8 a 100 watts por cada u$s1000 en tecnología. En promedio, cada 100 unidades de energía que ingresan a un data center, sólo 3 unidades se usan para procesamiento propiamente dicho. Más de la mitad se pierde en enfriar servidores. ¿ Cómo usamos los recursos de TI ? En entornos distribuidos el 85% de la capacidad de cómputo está ociosa.
