This document provides an overview and summary of key points from a presentation on designing virtual infrastructures and hypervisors. It discusses pre-requisites, assessing which servers are good candidates for virtualization, measuring server performance, determining the right amount of RAM for virtual machines, different types of virtualization technologies, high availability options, and live migration capabilities.

14. The Virtualization Assessment

15. The Virtualization Assessment Relatively Low Processor Use, but…

16. The Virtualization Assessment High Memory Pages/sec Ridiculous % Disk Time Crazy High Context Switches & Threads

19. Assessing the Right vRAM 2G of on-board RAM … minus… .5G of available RAM Let ’s consider a physical machine with 2G of on-board RAM … equals… Initial assignment of 1.5G of vRAM

21. Step 1 Purchase & Implementation

22. Consolidation = Cost Savings 8:1 15:1 20:1 Small Server $6,000 1:1 $6,000 per Server Large Server $15,000 Virtualization $5,000 $20,000 Large Marginal Cost Increases per Additional Server $2,500 per Server Smaller Marginal Cost Increases + Power + Cooling + Provisioning Labor $1,333 $1,000

30. Step 2 P2V

34. Step 3 High Availability

36. What Really is Live Migration? Part 1: Protection from Host Failures

37. What Really is Live Migration? Part 2: Load Balancing of VM/host Resources

42. Step 4 Backups Expansion

45. Three Types of Backups

48. Step 5 Virtualization at the Desktop

50. Step 6 DR Implementation
