  • Virtualization allows you to right size IT hardware to processing demand. While using the processing capacity (memory, storage, I/O capacity) to its maximum level instead of having many computers more or less running in idle mode, the question is no longer „how many servers do you need“ but „how much computing power do you need“. In a car pooling situation you would no longer ask for the number of cars needed, but for the number of seats...
  • Virtualization has clear and unambiguous benefits from the IT perspective, and these continue to be validated as virtualization continues its march toward becoming routine. So... data centers virtualize in the first place to improve efficiency... namely PROCESSING efficiency. And the gains there can be dazzling... 8 to 1... sometimes even 10 to 1 server efficiency gains are possible. And that directly lowers capex and opex. So from a MICRO perspective, inside the servers, the operational and energy benefits are obvious. BUT.... on the MACRO level, some surprising causes and effects emerge. And THAT’s what our message is. Once the IT systems are virtualized, and those capex and opex gains are beginning to appear, the virtualization story doesn’t end. The data center can become MORE unstable and costly as a direct result of virtualization... and the power and cooling infrastructure can become a wildcard if you don’t know how to do it right.
  • So, to summarize… virtualization is a fantastic tool in the efficiency tool box, but it has serious power and cooling implications beyond the well-publicized IT issues that you see all over the IT press these days. It should come with a warning label about the implications that many users may not understand, or even KNOW about. Ignoring that warning label can cost you big bucks that are waiting to be claimed, if only you know what to do to make it right.
  • To learn more about virtualization and how to optimize power and cooling to maximize benefits, APC White Paper #118 is the best all-around reference to consult. This white paper provides a lot of additional background and amplifying information on the topic of virtualization and it was a primary source of technical information used in developing this presentation. (Review the topics addressed by the white paper.) New slide/notes.

  • Virtualizarea î ntre extaz ş i agonie Eduard Bodor Data Center BDM for Central Europe Beneficii aduse şi provocări introduse
  • Increasing pressure Data Center … on data center planning and operation We created – and continue to improve – a new way to plan, design, install, manage, and maintain data centers In response … Energy and service cost control Increasing availability expectations Regulatory requirements Server consolidation Dynamic power variation Uncertain long-term plans for capacity or density Cloud computing Energy efficiency Virtualization
  • What is Virtualization?
    • Essentially, virtualization allows Right Sizing of hardware to the processing demand
    • This is the same message and value proposition InfraStruXure provides for the rack, power, cooling and management of the server room or data center
    One server Running many VMs Many servers Each running one OS/Application VM VM VM VM
    • Increased CPU utilization and efficiency
      • Typical server utilization rate: ~10-15% (usually higher in storage)
      • Virtualized utilization rate: Up to 80%
    • Server consolidation
      • Decreased need to purchase additional servers
    • Increased rack space
      • Reduced “white space” requirements
    • Improved continuity and disaster recovery
      • Virtualized servers can be mirrored in case of failure
    • Reduced labor costs
      • Easier hardware provisioning and maintenance
    Virtualization benefits
  • Where are customers using virtualization?
    • Enterprise customers were first to adopt
    • SMB adoption is early, but accelerating
      • Server consolidation - Virtualization technology to host several servers on one physical server
      • Disaster recovery - Maintain disaster recovery site without using same number of physical servers. For example, the daily backup can by placed on a standby virtual machine for rapid disaster recovery.
      • Test and development - Use of virtual machines to quickly provision and scale test machines and rapidly transition to newer projects
      • Client consolidation - Host several clients on high capacity servers, reducing the manageability burden associated with stand-alone clients
    • Low and inflexible utilization of computing infrastructure
    • Typically 10-15% server utilization
    • Idle and wasted capacity/power!
    Before After VM VM VM
    • Reduced total power draw of server population (Good)
    • Reduced floor footprint (Good)
    • BUT… power and cooling needs attention!
    • Less TOTAL power (because fixed loss of idle capacity is eliminated), so less TOTAL heat in the data center (Remember, kW power = kW heat)
    • If servers are physically consolidated into a smaller space , that smaller total amount of heat becomes intense and localized
    Heat is spread out Lots of wasted power due to “fixed losses” of idle capacity that is plugged in but not used for computing Application Operating System Application + OS Application Operating System Application + OS Application Operating System Application + OS Application Operating System Application + OS Application Operating System Application + OS Application Operating System Application + OS Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System

  • BEFORE virtualization: Room cooling is working Constant load day and night
  • AFTER virtualization: Pop-up hot spots 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  • Hot spots move around 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  • Hot spots move around 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  • Close-coupled cooling for hot spots
    • CRACs placed IN the rows, closer to hot spots
    • Unneeded perimeter CRACs removed

    • InfraStruxure Operations PRO Pack for Microsoft System Center Virtual Machine Manager
      • Provides insight into how virtual machines relate to physical servers and their location, automatically migrating virtual machines to secure host environments enabling customers to maintain Service Level Agreements and view and manage network health.
    • From power failure to IT impact
      • Problem:
        • The impact of critical power events are not effectively propagated to Virtual Machines (VMs)
      • Solution:
        • The critical events are translated into server impact analysis
        • VMs at risk are automatically migrated to healthy hosts
    • APC Solution requirements
