For this test, six PowerEdge R6525 servers are configured to host the VDI workload. vCenter is used to manage these servers as a cluster. Hosts with Intel or AMD processors support Horizon VDI workloads.
Careful planning is required to avoid bottlenecks that impact the user experience, such as hosts with inadequate or oversubscribed memory, CPU, or network bandwidth.
Host CPU oversubscription is a common practice with VDI and other virtual workloads. However, testing is recommended to determine the amount of CPU oversubscription that is supported for your workload without a degradation in performance.
Note: If the total VDI VM memory demand exceeds the available physical memory on a host, caching to disk is used. Caching can negatively impact the VDI user experience. Oversubscribing server memory should be avoided.
