VDI Performance Monitoring: How to Improve Your VDI Performance

Posted by VIOLIN SYSTEMS on Jan 6, 2021 5:05:04 PM

Virtual desktop infrastructure (VDI) has been described as, “The remote worker’s dream.” As a form of desktop virtualization, VDI hosts many desktops on a single, central server, which can be accessed by authenticated users.

This not only makes it easy to work from home—a practice which the importance of cannot be undersold in 2020 and beyond—but it makes it easy for employees to work from home securely. With VDI, organizations can access applications, operating systems, and information through a secure portal without sacrificing security, making it far easier to work remotely. VDI can even save companies as much as 30 percent on IT administrative costs

Sounds too good to be true, right? Sometimes it can be. When implemented or used incorrectly, VDIs offer poor, latency-ridden performance, especially if everyone tries to log in at once. 

The solution to these kinds of problems? VDI performance monitoring. 

Things You Should Know About VDI Performance Monitoring

What is VDI performance monitoring? Virtual desktop infrastructure performance monitoring is all about optimizing the performance of your virtual desktops. It’s the process of reviewing, monitoring, and managing the operations within the VDI environment to enhance performance, troubleshoot issues, and improve security. Performance monitoring is used to make sure that virtual desktops perform the way you need them to by fine-tuning the desktop environment. 

VDI monitoring can be a detailed process. It’s a series of steps and methods that span the IT and user sides of the virtual desktop environment. VDI monitoring can be done through a virtual machine monitor or a VDI-specific monitoring application like a virtual desktop manager (VDM). 

What kinds of things are monitored throughout the VDI?

  • User activity
  • Operational status and security of each virtual desktop
  • The total infrastructure
  • Resource utilization per desktop instance

Watch for These Areas Killing Your VDI Performance

A virtual desktop infrastructure can be useful anytime, but especially now while so much of our workforce is working from home. Organizations looking for secure ways to enable remote working have found a reliable solution in VDI, but only if they are operating in peak performance.

Without optimizing performance, VDIs can be slow to respond and tough to manage. Certain things can be affecting your VDI’s performance. Here are a few ways that the speed and efficiency of your VDI may be impacted:

Security Practices

As more and more organizations adopt virtualization technologies, they sometimes forget to change the way they handle malware protection and antivirus technologies. Physical and virtual servers call for very different approaches to remain secure. 

For physical servers, you would install unique antivirus and antimalware software on each server, which would have full access to the full machine on which it’s been installed. In this case, antivirus scans may impact performance a little bit, but not in a way that truly inhibits daily processes. 

In a virtual environment, antivirus and antimalware software need to be handled differently. When servers are virtualized and regular antivirus scans are run the same way they would be in a physical environment, it can really limit performance and place heavy burdens on resources. Instead, organizations need to implement virtualization-aware AV software to improve performance.


VDI environments leverage shared storage across multiple desktops—that’s what they’re designed to do. The problem is this splits the total number of available inputs/outputs per second (IOPS), which can dramatically slow down a desktop if not handled wisely.

To improve VDI storage and performance, it’s a good idea to carve out space in your physical array that’s dedicated solely to your organization’s physical desktop, so your VDI doesn’t have to compete for performance or contend with a connection broker to get its fair share of IOPS. What else can help with performance?

Using a solid-state drive.

You should always power your VDI from a solid-state drive (SSD) to optimize performance.

Endpoint Monitoring Tools

For far too long, troubleshooting a VDI was a mysterious process that usually involved rebooting it and hoping for the best. VDIs can be complicated to assess and fix, which means that many users accepted as fact that they would have a poor user experience. This meant that user adoption rates would be low and employees would be frustrated.

However, this doesn’t have to be the case anymore. With robust tools in place to monitor the end-user experience, you can boost performance, improve adoption rates, and locate issues when they arise to make the process of addressing issues an easier one.  

Your Network

Just like it makes sense to dedicate part of your array to powering your VDI, you should reserve network segments to your VDI workload as well. If you’ve been in the VDI game for a while, you may have already done this, but it’s worth mentioning since VDI performance can be deeply affected by a lack of network segmentation.

Think of it as a dedicated carpool lane on a busy highway. In a virtualized environment, your network is constantly active; it’s like a backbone that connects virtual memory (VM) to management, monitoring, and administrative tools and is responsible for communication to network-attached storage. All of these operations use a lot of your network resources, so by allocating a segment of your network to VDI in particular, you don’t lose out on performance because of a lack of network power. 

Benefits to Running Your VDI from a Powerful Array

Having a successful speedy VDI is more important now than ever before, and it’s critical to deliver a great end-user experience for your team members who are working remotely. The best way to make this happen is to power your VDI from a storage platform that’s built for the task.

We’ve already established that an SSD is the most solid choice for running a VDI, but an all-flash array is truly the way to go. VIOLIN’S QV2020 all-flash array isn’t just fast, it offers secure and consistent performance whether you need a simple virtualization infrastructure or you’re planning to run your VDI from a public or private cloud. Even during boot storms and at peak capacity, the QV2020 delivers steady, unwavering performance to keep your VDI environment moving quickly.

The VIOLIN QV2020 Powers:

  • Exceptional User Experience
  • Fortified Security
