Maximize Your Data Center for Virtualization Initiatives


Published on

Presentation focuses on the impact virtualization initiatives have on the data center and more importantly the critical
physical infrastructure supporting the data center. Virtualization is an IT strategy that can easily and quickly impact, with potential negative consequences, the reliability and availability of the data center. Understand the effects and some considerations in the implementation of virtualization.

  • Software based virtual machines allow for a great deal of flexibility in the datacenter.Virtual machines can:Power On/Off as needed -> Basing these applications on virtual machines provides for easy turn on/off capabilities when coupled with an IT Virtualization Management platform.Moves/Live Migration -> Virtual machine applications may start to push the physical server resources available on a host server. The IT Virtualization management platform can monitor and easily migrate the virtual machine to another physical server with the needed resources.Consolidation -> Perhaps an IT department would like to scale back virtual machine activities and consolidate virtual machines to a few servers. All of these scenarios described impact the datacenter physical infrastructure. What if the physical environment goes into alarm to power/cooling event? Where should the virtual machine go?If all physical servers are no longer hosting virtual machines can cooling devices be turned down?Tracking and Mapping physical infrastructure resources with physical and virutal servers is critical to maintaining a highly available data center environment.
  • (1) Running simulations is important for planning purposes (2) Supply/Demand split has shifted in a cloud environment demand is on storage space, compute and network access….(3)

    10. 10. Challenge 1: Power Density• Virtualization instantly drives up power densities at a rack level•Cooling challenge •Per tile airflow of 300-600 cfm hard to maintain •Raised flooring and perimeter cooling not the right choice•Power distribution Challenge •Need new breakers •New voltage supply levels•Weight-bearing capacities should be reviewedAPC by Schneider Electric – Pjilip Fischer – March 2011
    11. 11. Challenge 2: Dynamic Power/Cooling Is Mandatory ● Use power-capping with integration of DCIM and VM ● Need cooling system which can dynamically regulate cooling capacity ● DCIM works with VM Manager allowing for informed decision makingAPC by Schneider Electric – Pjilip Fischer – March 2011

    18. 18. Why Integrate Virtualization and Datacenter Management? ● Automate ● Virtual machine migration when an issue arises in the physical infrastructure ● Solve the issue ● Of keeping virtual machines running during physical infrastructure incidents ● Map dependencies ● Of physical servers to physical infrastructure ● Ensure your enterprise applications ● perform with the highest availability and performance ● Build up business continuity ● through improved disaster recovery solutions and deliver high availability throughout the datacenterAPC by Schneider Electric – Pjilip Fischer – March 2011
    19. 19. DCIM Definition ● A data center infrastructure management (DCIM) system collects and manages information about a datacenter’s assets, resource use and operational status. ● This information is then distributed, integrated, analyzed and applied in ways that help managers meet business and service-oriented goals and optimize their datacenter’s performance. ● In practice, DCIM systems may vary widely in focus, and complete solutions are likely to consist of a framework or suite of products, from one or many suppliers, that are designed to interoperate or complement each other. ● The close interworking of IT and mechanical/electrical systems will increasingly lead to the deployment of solutions that span data-center facility infrastructure, physical IT assets, and virtual IT assets.APC by Schneider Electric – Pjilip Fischer – March 2011
