The IT-Industry Has Benefitted with Login VSI


For many years now, Login VSI has been the undisputed IT-industry standard in VDI performance load-testing and benchmarking.

All IT vendors (both hardware and software) that are serious about providing their customers with a well-performing virtual desktop infrastructure (VDI), rely on Login VSI software solutions to design and build their products, and to communicate the tangible results to the public. The results of these research and development efforts are visible in many technical publications.

Technology vendors benefit from the Login VSI Vendor Edition (*) in three ways:

1. As a key component of the (behind the door) R&D process 
2. As the performance benchmark to communicate to the market
3. In POC's and pilots to compare infrastructure options, for sizing and scaling
and to do a full scale pre-production load-test/stress-test before production
(*) Login VSI’s Vendor Edition is the new name for classic load-testing solution Login VSI 4.1.

Avoid Problems with Login VSI Vendor Edition

Statistics from Login VSImax and Login VSIbase are widely used by all major IT vendors in VDI reference architectures, validated designs, white papers and presentations. They have grown into the de-facto industry standard statistics to communicate the scalability (VSImax) and the baseline end-user experience (VSIbase) of any centralized virtual desktop environment including VMware Horizon View, Citrix XenApp and XenDesktop, and Microsoft Remote Desktop Services (RDS), formerly known as Terminal Services.

As of 2017 the unique Login VSI testing methodology is officially patented. In addition to the methodology, the patent protects the metrics VSImax, VSIbase and the VSI threshold.

The Login VSI Vendor Program

For IT-vendors who want to position themselves more firmly in the Virtual Desktop Infrastructure space we offer the opportunity to showcase their publications on our website, and in our newsletter (60,000+ relevant readers). This service is available for vendors of hardware like servers, storage, appliances, network components, processors, and vendors of virtual desktop and other (e.g. security) software. We offer two formal programs to our vendor customers: ‘Tested with Login VSI’ and ‘Validated by Login VSI’.

Expert Testimonials:

Randy Groves - Teradici

"As the developer of the PCoIP protocol, we do a lot of our own internal benchmarking to make sure that we’re continuing to improve our protocol. But we can’t actually publish our internal benchmarks because everybody might think that the tests are biased. So when we want to publish results, we use Login VSI. That way, if a customer wants to repeat our results they can.”

Randy Groves, CTO at Teradici

Todd Mace - PernixData

"Login VSI has been a great partner for us. Customers use PernixData with Login VSI to help validate their user experience. Login VSI helps to see what their performance bottlenecks are and our software helps to mediate some of that. Login VSI has been a kind of defacto standard to be able to help that validation and help the customer to be able to come up with a solution to fix it."

Todd Mace, Product Manager at PernixData

Dan O'Farrell - Dell

"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."

Dan O'Farrell, Director, Product Marketing, Cloud & Client at Dell

Chris Gebhardt - NetApp

“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

  • "Login VSI is about quantifying the number of users I can get on VDI. It's a fantastic thing."

    Brian Madden - EUC guru and blogger at VMware

  • "Login VSI is the industry standard for benchmarking software. It's a key solution."

    Ruben Spruijt - Senior Technologist at Nutanix

  • "With Login VSI, we know what the impact is of new products and new Windows builds"

    Rob Beekmans - Technical Marketing Manager - Citrix

  • "The biggest benefit is gaining visibility of the performance of your environment."

    Christiaan Brinkhoff - Cloud Architect & Technical Evangelist - Microsoft

  • "Login VSI and Login PI allow us to provide a better user experience."

    Kilian Arjona - CTO - Flexxible IT

  • "I actively use Login PI for active monitoring. It helps track user-trends, see degradation through updates and Windows maintenance"
