Non-Volatile Memory Express (NVMe) is becoming the primary protocol for interconnecting modern storage technologies both within storage arrays and between storage arrays, storage networks, and...
Virtualizing desktops is no small undertaking as architects make decisions based on user requirements, use cases, platforms, devices and features to support, as well as what IT infrastructure is required to support their organization’s VDI needs.
Looking at an organization’s needs, task workers will perform work in ways that are different from office workers, sales people, remote developers or contractors. Vertical industries vary greatly in requirements for VDI. In education, students and teachers work differently from businesses and K-12 schools will differ in VDI needs from universities or technical schools. In healthcare, nurses and doctors require the ability to roam from patient to patient and access medical records quickly and securely. Other verticals that typically deploy VDI include state and local government, financial organizations, and manufacturing where security, mobility, and performance requirements can vary greatly.
Once VDI specifications and strategy are nailed down, the IT infrastructure required to support VDI needs to be architected. The success of a VDI project hinges on the satisfaction of your end-users, and that often starts and ends with the performance of the infrastructure put in place. Successful VDI projects depend heavily on highly performant storage. There are many options out there to consider, from traditional disk systems, to hybrid, converged infrastructure, hyper-converged or all-flash solutions.
Whether you choose to build your own, or choose a pre-engineered and validated solution, check out the full results of our white-paper published on FlashStack Converged Infrastructure with Citrix XenDesktop.
This FlashStack Converged Infrastructure is a validated reference architecture for VDI using Cisco UCS servers, Nexus switches, Pure Storage all-flash arrays and Citrix XenDesktop.
During the testing of this solution, we used an industry-recognized load testing tool. Login VSI simulates virtualized desktop systems and scales from a few virtual machines to thousands. By simulating scaling of VMs and desktops the tool is able to accurately show the absolute maximum number of VMs that can be deployed on a given host or cluster of hosts, using pre-defined classes of workloads that closely mimic real-world users. Using Login VSI enables customers to make educated decisions when evaluating various VDI architectures.
Here are a few of our top takeaways enabled via use of Login VSI:
Login VSI’s industry standard VDI test suite showed exceptional scaling of Citrix XenDesktop 7.6.1 from hundreds to thousands of users. While we did this testing, we also decided to showcase Pure Storage’s all-flash resilience. Our our engineer disconnected a fiber-channel cable during our 8 server, 1200 user simulation run and still experienced sub-ms latency throughout the simulation. As expected (and shown below), an error message showed up on our Pure Dashboard and an automated email alert was sent out, all while the system continued to perform flawlessly.
Here’s a sneak peek at what that will look like. Is that cool or what?
Here are a few more ways you can learn about how Pure Storage helps customers successfully deploy VDI with our all-flash storage solutions:
