  1. 1. Virtualizarea î ntre extaz ş i agonie Eduard Bodor Data Center BDM for Central Europe Beneficii aduse şi provocări introduse
  2. 2. 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
  3. 3. What is Virtualization? <ul><li>Essentially, virtualization allows Right Sizing of hardware to the processing demand </li></ul><ul><li>This is the same message and value proposition InfraStruXure provides for the rack, power, cooling and management of the server room or data center </li></ul>One server Running many VMs Many servers Each running one OS/Application VM VM VM VM
  4. 4. <ul><li>Increased CPU utilization and efficiency </li></ul><ul><ul><li>Typical server utilization rate: ~10-15% (usually higher in storage) </li></ul></ul><ul><ul><li>Virtualized utilization rate: Up to 80% </li></ul></ul><ul><li>Server consolidation </li></ul><ul><ul><li>Decreased need to purchase additional servers </li></ul></ul><ul><li>Increased rack space </li></ul><ul><ul><li>Reduced “white space” requirements </li></ul></ul><ul><li>Improved continuity and disaster recovery </li></ul><ul><ul><li>Virtualized servers can be mirrored in case of failure </li></ul></ul><ul><li>Reduced labor costs </li></ul><ul><ul><li>Easier hardware provisioning and maintenance </li></ul></ul>Virtualization benefits
  5. 5. Where are customers using virtualization? <ul><li>Enterprise customers were first to adopt </li></ul><ul><li>SMB adoption is early, but accelerating </li></ul><ul><ul><li>Server consolidation - Virtualization technology to host several servers on one physical server </li></ul></ul><ul><ul><li>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. </li></ul></ul><ul><ul><li>Test and development - Use of virtual machines to quickly provision and scale test machines and rapidly transition to newer projects </li></ul></ul><ul><ul><li>Client consolidation - Host several clients on high capacity servers, reducing the manageability burden associated with stand-alone clients </li></ul></ul>
  6. 6. <ul><li>Low and inflexible utilization of computing infrastructure </li></ul><ul><li>Typically 10-15% server utilization </li></ul><ul><li>Idle and wasted capacity/power! </li></ul>Before After VM VM VM <ul><li>Reduced total power draw of server population (Good) </li></ul><ul><li>Reduced floor footprint (Good) </li></ul><ul><li>BUT… power and cooling needs attention! </li></ul><ul><li>Less TOTAL power (because fixed loss of idle capacity is eliminated), so less TOTAL heat in the data center (Remember, kW power = kW heat) </li></ul><ul><li>If servers are physically consolidated into a smaller space , that smaller total amount of heat becomes intense and localized </li></ul>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
  7. 7. Power and cooling need to be optimized too! POWER infrastructure COOLING infrastructure Right-sized, efficient, LEAN power and cooling Right-sized, efficient, LEAN server utilization Actual POWER needed Actual COOLING needed Less TOTAL power, less TOTAL heat, but now LOCALIZED Need to decommission unused capacity to save electrical cost of “fixed losses” of power and cooling systems THE GOAL: PLUS BEFORE virtualization AFTER virtualization and consolidation Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System VM VM VM Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System Application Operating System 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
  8. 8. BEFORE virtualization: Room cooling is working Constant load day and night
  9. 9. AFTER virtualization: Pop-up hot spots 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  10. 10. Hot spots move around 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  11. 11. Hot spots move around 7am – 8 am 9am – noon Lunchtime 1pm – 4pm 4pm – 6pm 6pm – 7am 8am – 9am
  12. 12. Close-coupled cooling for hot spots <ul><li>CRACs placed IN the rows, closer to hot spots </li></ul><ul><li>Unneeded perimeter CRACs removed </li></ul>Perimeter CRAC removed Perimeter CRAC removed
  13. 13. Expanding integrations <ul><li>InfraStruxure Operations PRO Pack for Microsoft System Center Virtual Machine Manager </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>From power failure to IT impact </li></ul><ul><ul><li>Problem: </li></ul></ul><ul><ul><ul><li>The impact of critical power events are not effectively propagated to Virtual Machines (VMs) </li></ul></ul></ul><ul><ul><li>Solution: </li></ul></ul><ul><ul><ul><li>The critical events are translated into server impact analysis </li></ul></ul></ul><ul><ul><ul><li>VMs at risk are automatically migrated to healthy hosts </li></ul></ul></ul><ul><li>APC Solution requirements </li></ul><ul><ul><li>InfraStruxure Operations & InfraStruxure Capacity v6.1 </li></ul></ul><ul><ul><li>InfraStruxure Operations PRO Pack – SKU: SFVMM2008R261 (free download) </li></ul></ul>
