You Will Learn How To
- Diagnose and troubleshoot configuration issues in the vSphere environment
- Exploit built-in graphical and command-line tools for problem analysis and correction
- Optimise memory and CPU resource allocation to mitigate performance issues
- Resolve networking and accessibility failures within the storage architecture
- Restore optimal DRS cluster management by eliminating vMotion errors
- Enforce resiliency by identifying and correcting HA operational problems
Course Benefits
As organisations increasingly adopt virtualisation, they must ensure rapid response time to issues that can affect system availability and cause costly downtime. In this course, you diagnose and correct configuration issues, ensure optimal resource allocation and availability, and apply a series of proven tools and techniques to troubleshoot potential problems.
Who Should Attend
Network and storage analysts, administrators and anyone who wants to troubleshoot the vSphere infrastructure. Experience with vSphere at the level of Course 171, "Deploying VMware vSphere", is assumed.
Hands-On Training
Hands-on exercises provide practical experience troubleshooting VMware vSphere, and include:
- Utilising CLI for problem resolution
- Uncovering performance metrics using esxtop
- Setting up a syslog system
- Analysing memory management mechanisms
- Troubleshooting vSwitch configuration
- Isolating and correcting DRS problems
- Evaluating admission control in clusters
- Resolving DRS migration failures
- Mitigating host isolation response in clusters
