The VxBlock System 1000 converged infrastructure platform provides a highly scalable and resilient system for VDI workloads along with exceptional user experience. Analysis of the results have shown that storage, network and memory were not a bottleneck during the testing we performed with the C7 configuration. However, CPU utilization was close to the threshold we set and was a decisive factor in recommending the user densities outlined in this document. The Login VSI results shows that VSI Max never reached the VSI threshold for the knowledge worker workload tested, which indicates a stable system with excellent EUE.
The configurations for the VxBlock System 1000 converged infrastructure have been optimized for VDI. We selected the memory and CPU configurations that provide optimal performance. You can change these configurations to meet your own requirements, but you should be aware that changing the memory and CPU configurations from those that have been validated in this document will affect the user density per host.
With the introduction of the six-channels-per-CPU requirement for Skylake processors, the C7 memory configuration recommendation has increased from the previous guidance of 512 GB to 768 GB. This change was necessary to ensure a balanced memory configuration and optimized performance for your VDI solution. The additional memory is advantageous, considering the resulting increase in operating system resource utilization and the enhanced experience for users when they have access to additional memory allocations.
With a flexible choice of fully integrated Dell EMC storage and data protection, Cisco UCS servers and networking options backed by VMware virtualization, the VxBlock 1000 platform provides the capability to run an enterprise-level VDI environment. VxBlock 1000 is also capable of running a multiworkload environment that includes VDI and high-value applications, data analytics and so on.
