Taking charge of VM allocation, troubleshooting methods

Last updated:February 2018

Editor's note

Virtualization admins are responsible for ensuring data center operations are running smoothly, but as with most jobs in IT, that's easier said than done. Virtual infrastructures are made up of many moving parts -- virtual machines, applications, workloads and so on -- and even a small problem left unresolved can lead to downtime or system failure.

Admins need to make sure their hardware resources can support the virtual machines (VMs) they need to run, and that their environments can scale as workloads increase. As more organizations consider virtualizing mission-critical workloads, and the IT industry shifts toward a software-defined future, getting the highest VM performance is becoming even more important.

As such, effective data center management needs to include capacity planning, VM allocation, troubleshooting methods and the right monitoring tools. This essential guide will cover the basics, as well as more advanced tips for admins to optimize server and VM performance.

1Choose proper management tools

As virtualization infrastructures grow in size and complexity, they're becoming more difficult to manage. Although there are tools that can help virtualization admins better manage their VMs and workloads, selecting the best tool can be a challenge. Even after doing careful research and choosing a management tool, admins need to plan for implementation. Make sure you're laying the proper groundwork to take full advantage of these tools.

2Troubleshoot common virtual infrastructure problems

Finding an issue in the data center is one thing, but solving the problem is another matter entirely. Unfortunately, both tasks can be challenging and time-consuming, as performance issues can be caused by any number of things, including overprovisioning and VM sprawl. By implementing best practices and taking advantage of certain tools, virtualization admins can minimize downtime and get data center operations back to normal.
