State of Adoption of Server Virtualization
Operational Challenges / Barriers
Server Virtualization Technologies ,[object Object],The goals:  Enable more VMs on a single chip, minimize cpu overhead for IO, and enable monitoring & management Technology Example 1 Example 2 Differentiators Virtualization Software WMware’s  vSphere/ESXi Microsoft’s Hyper-V (W2008 Server) ,[object Object],[object Object],Processor architecture Intel Xeon 7500 8-core AMD Opteron 6000 12-core ,[object Object],[object Object],Disk IO Interface iSCSI FCoE ,[object Object],[object Object],Network Interface Broadcom iSoE Intel I/OAT ,[object Object],[object Object],Management Utilities VMware’s vCenter MS Virtual Machine Manager ,[object Object],[object Object]
Six Critical Factors for Testers ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
1 - Anatomy of a Virtual System ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Type 1 Virtualized Server
2 - Virtual Workload Modeling ,[object Object],[object Object],[object Object],[object Object],4 Key Questions: Web App Files DB Hardware
2a - VMware Capacity Planner ,[object Object],[object Object],[object Object],[object Object]
3 - VM Bottlenecks & Vulnerabilities ,[object Object],[object Object],[object Object],[object Object],App servers on different hosts
4 - Performance Testing Techniques ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
5 - System Resources to Measure ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
5a - Monitoring Host Resources VCenter monitoring host resources kry, in addition to monitoring resources on individual VMs, to id IO path bottlenecks
6 – Presenting Comparative Results Business process end-end response over load on same graph Overall response profiles btwn dedicated and virtual platforms similar
6a – Comparative Page Times Differences btwn dedicated and Virtual page response times over load Average difference: Virtual 7% faster on average Max difference: “a wash” (Virtual 1% faster on average)
6 b – Comparative CPU VM utilizations higher than on dedicated servers, but still low
6c – Comparative Bandwidth Bandwidth usage similar in magnitude, profile
Case Study: SAMPLE ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Solution Business Challenge ,[object Object],[object Object]
Environment Migration 18 dedicated, underutilized servers… … migrated to 3 Virtual Hosts… … with proven performance & reliability
Customer Benefits ,[object Object],[object Object],[object Object]
In Conclusion ,[object Object],[object Object],[object Object]
