Mastering P2V: Best Practices for Maintaining Service Levels upon Migration


Published on

No doubt you are familiar with the established benefits of virtualization: improved efficiency and resource availability at a lower overall cost. Many IT departments, however, have discovered that virtualizing applications can create new and unexpected performance problems.

As businesses drive towards the distributed IT infrastructure model, how can you be sure that your application performance and service levels will not be sacrificed following P2V migration?

Join Correlsense and Emulex for an online seminar on how your business-critical applications can survive P2V migration without a performance degradation. During this session, we will discuss:

-The growing complexity of the modern IT infrastructure and the accelerating pace of change
-The challenges of guaranteeing service levels before, during and after a P2V migration
-The importance of end-to-end visibility in monitoring application and storage performance

We will conclude with a discussion of the Correlsense and Emulex solutions plus Q&A.

  4. 4. Why Application and I/OPerformance are Crucial for P2V
  5. 5. What The Experts Are Saying … 50% “..half or more of the database time is attributable to storage I/O” Storage - Gartner’s Sept 2011, “Magic Quadrant for Application Performance Monitoring” Wait Time “It is vital to understand the value of performance for each environment and particular application.”“Improving [storage I/O “The cost for I/O response time needs to be part of thecompletion time] will have data center cost structure.”a dramatic effect on - IDC, ‘Data Center I/O Performance Issues and Impacts’[application] transactionrate and scalability.”– Pure (Matt Kixmoeller) “Measuring application response time and transaction throughput is the only way to ensure acceptable performance before, during, and after [migration] to a virtualized or private cloud environment.” – Virtualization (Bernd Harzog) © 2012 Emulex Corporation & Correlsense Inc. 5

  7. 7. The End-to-End (E2E) Challenge Complexity is growing in the data center – Virtualization brings efficiency gains but complexity challenges – Service-oriented architectures mean performance management now a holistic undertaking Administrators are being pressured to – Reduce the time to deploy new applications and technologies – Increase the number of applications and technologies supported – Extend the performance of existing infrastructure The challenge… – How to manage application availability and performance SLAs? – Domain-specific monitoring lacks holistic visibility © 2012 Emulex Corporation & Correlsense Inc. 7
  8. 8. Unspoken Fear of P2V Traditional physical hardware is predictable and dedicated Virtual infrastructure introduces sharing, over-subscription Application performance before migration will not match application performance post migration. Solutions may be out of our control as the hardware resources are not managed by others. There is no way to go back. © 2012 Emulex Corporation & Correlsense Inc. 8
  9. 9. Why Application Owners Should CareAbout storage – and Vice Versa New storage configuration options – Application performance enhanced by fine-tuning storage components – Server hardware performance gains increased significance of storage performance – Data analytics increases reliance on robust storage performance Application vs. Storage – “Who’s problem is it, anyway?” Problem Application Storage Web-site performance To many embedded objects? Static content is on a slow storage device? On-line app Missing index? DB lock? Bad Peak usage is causing large performance query? storage queues, making app wait?

  10. 10. P2V Best Practices
  11. 11. Are You Ready for P2V? Don’t start without a plan – Identify dependencies for apps and storage – Prioritize order of virtualization Plan Baseline ‘real-world’ infrastructure performance – Establish where you are now and where you want to be Baseline Establish robust SLAs Create – Measure from end user through to storage SLAs Early warning & continuous monitoring – Automate SLA monitoring Monitor, R eport, Rea – Pro-active alerting based on dynamic performance thresholds ct © 2012 Emulex Corporation & Correlsense Inc. 11
  12. 12. Will You Have E2E visibility When You Migrate? Traditional tools are insufficient for end-to-end performance management “CPU and “PING works, “SAN has low “Plenty of Storage & Memory are OK” Temp is OK” utilization” No hardware failures” Application Database X Server Server Fabric Storage Target Application Server SAN Performance SW Mgmt. SW Mgmt. SW Array Mgmt. SW SRM Tools “Plenty of capacity” © 2012 Emulex Corporation & Correlsense Inc. 12
  13. 13. P2V Checklist Assure service-levels while migrating to a virtualized environment – e.g. under-provisioning of application nodes, over utilization of LUNs!? Cross the stack service level assurance - don’t move without it Physical server / port oversubscription 8:1 Unintended spindle LUN 0 ! contention Target Port A RAID LUN 1 Set 1 ! ! Target Port B LUN 0 RAID ! Set 2 ! LUN 1 Virtual Physical Storage Storage Virtual oversubscription 160:1 (20 guest / hypervisor) © 2012 Emulex Corporation & Correlsense Inc. 13
  14. 14. The 5 Layers of User Frustration Here, with pro- active monitoring 1. User notices slow application and ignores 2. User hounded by slow app and tries When does IT their own fix (e.g. refresh/restart) find out? &%#! 3. User frustrated by slow app and &%#!s to friend or co-worker Here, with reactive “monitoring” 4. Severe disruption - user complains to IT or Customer Service 5. System unusable © 2012 Emulex Corporation & Correlsense Inc. 14
