Designing a large-scale VMware View solution is a complex task. The challenges faced in large deployments may be faced in small deployments if VMware-validated maximums and limits are not observed.
There are tools to help administrators understand requirements and constraints from graphics, CPU, memory, and storage perspectives. Other tools help to calculate the infrastructure size based on the number of virtual desktops, average IOPS, memory size, percentage of shared memory, percentage of used memory, percentage of read/write IOPS, and so on.
No matter what results these tools provide, the VDI architect should always ensure that the numbers are within VMware vSphere and VMware View limits.
