About Login VSI, Inc.

Login VSI provides performance insights for virtualized desktop and server environments. Enterprise IT departments use Login VSI products in all phases of their virtual desktop deployment—from planning to deployment to change management—for more predictable performance, higher availability and a more consistent end user experience.

6 steps for the best VDI performance

Desktop virtualization promises flexibility, centralized management and data, and better security. But at the end of the day, VDI success comes down to one thing: End user experience. Whether you are using Citrix, VMware or Microsoft, the inherent complexity of your environment, compounded by constant application updates, can and will affect performance in your VDI environment. To help you to deliver a predictable performance, higher availability and a more consistent end user experience in every phase of your deployment, we would like to introduce the VDI lifecycle.

What our customers are saying

Chris Gebhardt

“We use Login VSI to make sure that what we are recommending to our customers is much better than what their guesses are. Because if you don't do proper assessment and if you don’t use Login VSI, your architecture is just a guess.”

Chris Gebhardt, Senior Technical Marketing Engineer at NetApp

Kelly Murphy

"Ultimately, VDI is about performance. If a customer's virtual experience is not as fast as the physical experience, they don’t use it. Login VSI is great in helping us to really quantify and to show performance, to test systems and design those systems in such a way to ensure that you can deliver that kind of performance."

Kelly Murphy, CTO and Founder at Gridstore

Dan O'Farrell

"The primary goal of our VDI appliances is to simplify and to take the guesswork out of VDI, and the Login VSI tests help us to do that from a performance expectation capability. When we offer one of our appliances to our customers, we deliver benchmarks that are validated using multiple Login VSI workloads. When compared to a customer’s workload, these Login VSI-enabled benchmarks allow precise sizing estimations to be created."
