  3. 3. What is ITIL (v3)?<br />Good practice for IT Service Management<br />Based on the Service Management Lifecycle<br />Service Strategy<br />Service Design<br />Service Transition<br />Service Operation<br />Continual Service Improvement<br />
  4. 4. ITIL Capacity Management<br />Goal<br />Purpose<br />Objectives<br />Scope<br />
  5. 5. ITIL Capacity Management<br />Three levels of Capacity Management<br />Business<br />Service<br />Component<br />Requirements most often flow “top-down” and data and information “bottom-up”<br />
  6. 6. Capacity Management Activities<br />Iterative activities<br />Monitoring, Analysis, Tuning, Implementation<br />Demand Management<br />Modeling<br />Application sizing<br />Modeling<br />Storing data in the CMIS<br />Completing the Capacity Plan<br />
  7. 7. Capacity Management: Basic questions that need answers<br />What is the expected business growth next year, and how will it affect our IT infrastructure?<br />Which infrastructure items (servers and logical components) are serving which business applications and services?<br />How will the relationship between the underlying components affect services levels and in a wider context the business that uses them?<br />Which infrastructure components can be consolidated without degrading service levels?<br />
  8. 8. Today’s Capacity Management Challenge<br />Planning ahead to achieve service levels while managing:<br />
  9. 9. Many kinds of data needed<br />Business data<br />Service data <br />Component data<br />Financial data <br />Relationships<br />
  10. 10. Sharepath from Correlsense<br />Allows you to monitor all real-user transactions in production<br />Allows you to capture statistics from all the hops in the infrastructure<br />Builds a map that shows the relationships between IT components even in very complicated environments<br />Provides statistics for many different functions in an organization, including Capacity Management<br />

  12. 12. How SharePath Works<br />Patent pending technology<br />No need for code change<br />Stores 100% of all traffic – by design<br />No manual modeling<br />Negligible overhead <br />Individual Transaction Path Detection<br />Transaction and Application Modeling<br />Auto-detection of dependency topology<br />
  13. 13. Aligning Business and IT for Optimized Planning<br />Transactions are the missing link that tie together infrastructure, applications and the business<br />
  14. 14. Aligning Business and IT for Optimized Planning<br />By tracking transactions through all hops, SharePath creates valuable, business-contextual data<br />
