Virtual desktop infrastructure (VDI) plays a crucial role in today's business transformation initiatives. VDI is the most efficient way to present Microsoft Windows applications to users in their digital workspaces and provides a consistent user experience across devices for the modern-day mobile workforce. Organizations increasingly rely on VDI to provide the agility, security, and centralized management that is so important for their workforce.
It is often challenging for organizations to set up a VDI infrastructure. This challenge is mainly because a typical VDI infrastructure involves the integration of multiple data center components such as storage, network, and compute. The multivendor profile of these components often creates challenges during deployment and can also affect the system's performance if it is not optimized for VDI.
To consistently maintain a multicomponent and multivendor environment with a specialized skill set is challenging for most organizations. The effort to maintain a stable VDI infrastructure can have a negative impact on your total cost of ownership (TCO).
Dell EMC Ready Architectures for VDI based on Dell EMC XC series appliances is a perfect solution for your VDI workloads. These hyperconverged appliances integrate Dell EMC PowerEdge servers, Nutanix software, and a choice of hypervisors to run any virtualized workload you choose. You can deploy an XC cluster in 30 minutes and manage it without specialized IT resources. XC Series solutions eliminate the need for over-provisioning and capital expenditures that are based on anticipated capacity and performance requirements.
System performance and capacity can be easily expanded one node at a time with zero downtime, offering customers linear and predictable scale-out expansion and pay-as-you-grow flexibility. A fault-tolerant architecture and self-healing capabilities provide system reliability and help ensure data integrity. You will have an enterprise-level infrastructure with rapid deployment, less time needed for routine management tasks, faster system restoration, and integrated enterprise class data protection. Moreover, Dell EMC's Global Service and Support organization fully supports all XC Series hardware, software, and deployments.
For customers who have chosen a Nutanix-based environment, Dell EMC recommends XC Family devices that are optimized for VDI workloads to run VMware Horizon 7 VDI infrastructure. VMware Horizon 7 has a streamlined approach to delivering and managing virtual desktops and applications, providing a consistent user experience across devices and locations while keeping corporate data secure and compliant. XC series appliances—the XC740xd-24 (2U) and the XC640-10 (1U)—are designed for compute- and performance-intensive workloads in VDI. XC740xd-24 devices also support GPU hardware for graphics-intensive desktop deployments.
The Dell EMC Ready Architectures for VDI team tests VDI solutions to ensure their validity. As part of the testing process, engineers tune the system to maximize performance and efficiency, and document best practices. Finally, a separate team of experts evaluates the test results to ensure that the systems are properly configured and sized for customers. In the validation effort described in this guide, we have used the Login VSI tool, which is an industry standard tool for benchmarking VDI workloads. We tested typical Login VSI workloads such as Task worker, Knowledge worker, Power worker, and Multimedia worker with each workload being accompanied by an appropriate desktop virtual machine (VM) profile (that is, vCPU count, memory configured on the VM and so on.). This document provides a detailed analysis that is based on those test results. We recommend user density figures for these workloads while giving the utmost importance to the user experience.
