Sizing guidelines

  • Memory

    The VDI memory size allocated to the VDI and AI VMs must be considered on this solution. As all memory is reserved on virtual machines with vGPU acceleration, the total amount of memory reserved by the VMs cannot exceed the amount of physical memory in the host.

    Populate memory in units of eight DIMMs per CPU to yield the highest performance. Dell Technologies PowerEdge servers using third generation Intel Xeon Scalable processors have eight memory channels per CPU, which are controlled by four internal memory controllers, each handling two memory channels. To ensure that your environment has the optimal memory configuration, use a balanced configuration, where each CPU supports a maximum of 16 DIMMs (or 32 DIMMs for a dual-CPU server). The most effective configuration is 16 DIMMs (8 per processor) with Intel Xeon Scalable processors.
