Overview
The Dell VDI team has provided extensive performance testing results and guidance based on the PAAC testing carried out with the Login VSI Task Worker workload. The 3rd Generation Intel Xeon Scalable processors in our "Memory optimized" configuration provide performance, density, and agility for your VDI workloads.
The configurations for the VxRail appliances are optimized for VDI. We selected the memory and CPU configurations that provide optimal performance.
User density recommendations
The recommended user densities in the following table were achieved during the performance testing on VxRail appliances. We followed the VMware best practices of FTT = 1 and configured a reserved slack space of 30 percent. Login VSI Task Worker was tested with Windows Server 2022 and Microsoft 365 with Office Apps. We implemented all mitigations to patch the Spectre, Meltdown, and L1TF vulnerabilities at the hardware, firmware, and software levels to ensure an improved performance impact, which is reflected in the achieved user densities.
The following table shows the recommended user densities:
Node configuration | Workload | Windows version | User density | Users per instance |
Memory Optimized | Login VSI Task Worker | Server 2022 21H2 | 260 | 4 |
