This section describes the key hardware and software components of the solution.
PowerEdge rack servers provide the highest performance for a diverse set of workloads. They’re designed to speed deployment and improve application performance for VDI environments. As workloads and workplaces become more complex, it becomes more important than ever for businesses to have end-to-end solutions that work together seamlessly. Powerful, simplified, and automated OpenManage tools help to manage large clusters easily and effectively, while robust security is built into the servers to protect against malicious activity.
Because PowerEdge servers do not offer life cycle management and additional bundled software, Dell Technologies recommends customized deployment services and at least three years of ProSupport Plus. Add VMware Horizon 7 Advanced or Enterprise to license your PowerEdge servers for a full VDI deployment.
The Dell EMC PowerEdge R6515 is a 1-socket, 1U rack-based server that is designed to run complex workloads, using highly scalable memory, I/O, and network. The system is based on the 2nd Gen AMD EPYC processor (up to 64 cores), has up to 16 DIMMs, PCI Express (PCIe) 4.0-enabled expansion slots, and a choice of LAN-on-Motherboard (LOM) riser technologies.
The R6515 is a general-purpose platform capable of handling demanding workloads and applications and is the ideal AMD EPYC-based platform for hosting the VDI management components.
For more information, see PowerEdge R6515 Rack Server.
The Dell EMC PowerEdge R7525 is a 2-socket, 2U rack-based server that is designed to run complex workloads using highly scalable memory, I/O capacity, and network options. The system is based on the 2nd Gen AMD EPYC processor (up to 64 cores), has up to 32 DIMMs, PCI Express (PCIe) 4.0-enabled expansion slots, and OCP 3 Mezzanine networking options.
The R7525 is a highly adaptable and powerful platform capable of handling a variety of demanding workloads while also providing flexibility. This server is the ideal AMD EPYC-based platform for hosting the VDI compute components.
For more information, see PowerEdge R7525 Rack Server.
For graphics-intensive desktop deployments, we recommend the VDI-optimized 2U servers that support GPU hardware.
The R7525 can be configured with or without GPUs. Dell Technologies also offers similar configurations in a 1U/1 node appliance, although fewer graphics configurations are available on these platforms.

vSAN is available in hybrid or all-flash configurations.
After vSAN is enabled on a cluster, all disk devices that are presented to the hosts are pooled together to create a shared data store that is accessible by all hosts in the VMware vSAN cluster. VMs can then be created with storage policies assigned to them. The storage policy dictates availability, performance, and available capacity.
vSAN provides the following configuration options:
NVIDIA vGPU brings the full benefit of NVIDIA hardware-accelerated graphics to virtualized solutions. This technology provides exceptional graphics performance for virtual desktops and virtual workstations when sharing a GPU among multiple users.
NVIDIA vGPU is the industry's most advanced technology for sharing or aggregating true GPU hardware acceleration between multiple virtual desktops without compromising the graphics experience.
NVIDIA vGPU offers four software variants to enable graphics for different virtualization techniques:
Dell EMC Ready Solutions for VDI can be configured with the following NVIDIA GPUs for an optimum user experience that is hosted from your data center:
As a best practice, ensure that members of a VMware vSAN-based cluster are identical or as homogeneous as possible in terms of hardware, software, and firmware. This practice is primarily to reduce operational complexity and maintenance requirements. When deploying NVIDIA vGPU and the associated NVIDIA GPUs in a PowerEdge environment, a mixed GPU environment may be necessary or beneficial for several reasons, including:
If a mixed GPU configuration is unavoidable, consider the following information when planning and designing within a VMware Horizon VDI environment:
Consult your Dell Technologies account representatives to discuss a long-term hardware life cycle plan that gets the best value out of your investment and solution.
Ready Solutions for VDI solutions allow for flexibility in networking selections. VDI validations have been successfully performed with the following hardware, although several other choices are available:
Designed for true linear scaling, PowerEdge servers use a leaf-spine network architecture, which consists of two network tiers: an L2 Leaf and an L3 Spine that is based on 40 GbE and non-blocking switches. This architecture maintains consistent performance without any throughput reduction.
VMware vSphere provides a powerful, flexible, and secure foundation for business agility that accelerates the digital transformation to cloud computing and promotes success in the digital economy.
vSphere provides the following benefits for VDI applications:
The architecture that this guide describes is based on VMware Horizon 7, which provides a complete end-to-end solution delivering Microsoft Windows virtual desktops to users on a wide variety of endpoint devices. Virtual desktops are dynamically assembled on demand, providing users with pristine, yet personalized, desktops each time they log in.
VMware Horizon 7 provides a complete virtual desktop delivery system by integrating several distributed components with advanced configuration tools that simplify the creation and real-time management of the virtual desktop infrastructure.
The core Horizon components include:
Horizon clone technology
VMware Horizon 7 offers the following methods for cloning desktops:
