Citrix XenDesktop on Nutanix is a powerful solution that offers unrivaled user experience, simple administration, and web-scale flexibility and economics. In this reference architecture, we make recommendations for the design, optimization, and scaling of XenDesktop deployments on AHV. We used Login VSI and an intelligent scripting framework on Nutanix to simulate real- world workloads in a XenDesktop environment. The Nutanix Enterprise Cloud Platform offers high IOPS and low latency. Our testing demonstrates that host CPU resources drive desktop user density, rather than concerns about I/O or resource bottlenecks—you can easily deploy 150 knowledge worker desktops per node, with four nodes per 2RU appliance. In addition to desktop and application performance reliability, when deploying XenDesktop on Nutanix you get unlimited scalability, data locality, AHV clones, and a single datastore. Nutanix also takes the Citrix commitment to simplicity to another level, with streamlined management, reduced rollout time, and lower operating expenses.
