DOWNLOAD [NUTANIX] - Citrix XenDesktop on vSphere Reference Architecture
This document makes recommendations for the design, optimization, and scaling of Citrix XenDesktop deployments on Nutanix.
It shows the scalability of the Nutanix virtual computing platform and provides detailed performance and configuration information about the cluster’s ability to scale when used for XenDesktop deployments.
We used Login VSI to simulate real-world workloads and the conditions of a XenDesktop environment using MCS and PVS on Nutanix. The sizing data and recommendations in this document derive from multiple testing iterations and thorough technical validation.
We completed the solution and testing data with Citrix XenDesktop deployed on VMware vSphere, both running on the Nutanix virtual computing platform.
In a Citrix XenDesktop deployment on Nutanix, desktop user density will be based primarily on the available host CPU resources, not I/O or resource bottlenecks for MCS and PVS deployments on Nutanix. Login VSI Office Worker test results showed that densities of over 120 Office Worker desktops per node (counting four per 2U appliance) are possible. However, most VDI deployments are relevant to the Knowledge Worker category.
The Login VSI Knowledge Worker test demonstrated that this category is capable of accommodating more than 100 desktops per node, including four per 2U appliance.
We determined sizing for the pods after carefully considering performance and after accounting for additional resources for N+1 failover capabilities.
