DESCRIPTION
Did you know that 53% of all companies have VMware servers with Performance degradation due to Memory Swap In/Swap Out? This presentation details a survey of the top 5 VMware performance issues. We will share how businesses can evaluate and evolve their network infrastructure performance and get the most out of their VMware Infrastructure. This presentation explores the VMware Troubleshooting Guide and how to use that information to improve your environment. - Which overlooked items can have the most impact on your VMware performance - How to use information that is available at your fingertips - How to gather this information in your own environment - And the best practices for delivering high-performance VMware to support your business

- 10. # 5 Most Common VMware Issue 33% of businesses have CPU
oversubscription within their VMware hypervisors Learn More: VMware
recommends less than 5% ready time for all VMs

- 13. # 2 Most Common VMware Issue 63% of VMware systems have
swap wait
- 14. # 1 Most Common VMware Issue 64% 26% 64% of organizations
have receive packet loss occurring on virtual switch ports and 26%
have transmit packet loss occurring on virtual switch ports
- 15. Survey Question What Vmware Performance & Monitoring
Tools Are You Using?
- 16. Before After Establishing a Performance Baseline
- 17. Infrastructure Performance Statistics 10 In order to
establish an effective baseline, you have to focus on more than ONE
dimension. 9 8 7 6 5 4 3 2 1 Infrastructure Performance Statistics
CPU Usage
- 18. Cross-Functional Analysis Data Center 54% Vmware Perf
Problems 33 % Oversubscribed Line Cards 47 % Storage Perf Problems
73 % Network Perf Problems 1. 2. 3. 4. 5. Dont Just Focus on CPU
usage Analyze Disk I/O Analyze Network I/O Capture Network Traffic
Look at the network relations and dependency
- 19. Analyze, Dont Monitor VS
- 20. Collect (at least) the following data CPU Usage % % Steal
time OR % Ready Time Data Collection Memory Swap In/Out Rate
(hypervisor if virtual) CPU % Wait Time (can show disk slowness for
swapping) VM Swap Wait Disk IOPS (I/O Per Second) I/O Block Size
Latency and Queue Length Network Packet Loss % Delay
- 21. How to analyze my Environment?
- 22. Gather Data General usage info for CPU, Memory, Disk
Current usage and impact on performance Current network performance
information Virtualized environment analysis
- 23. Benchmarking Clearly identify specific areas of opportunity
Set performance expectations Validate infrastructure assumption
Monitor company performance and manage change
- 24. Resources Performance and Troubleshooting Guide
