Understanding sizing requirements

Performance bottleneck of any infrastructure is linked directly to the sizing of its base infrastructure components. So, it's very important to ensure that any new environment that is being designed is built efficiently using proper sizing guidelines.

In this section, we will cover the basic sizing requirements of a XenDesktop environment, which is the key for a successful deployment.

For any XenDesktop deployment, you need to work on sizing the following components:

• Number of infrastructure servers

• vRAM and vCPU requirements for the infrastructure servers

• vRAM and vCPU requirements for VMs

• Base hardware required for the hypervisor layer

• SQL databases

• Storage

• IOPS requirements

• Bandwidth requirements

• vGPU and HDX 3D Pro sizing

Earlier, we sized the environment based on the data captured by enabling Perfmon counters on the VDI/server to measure the concurrent user load, memory/CPU stats, IOPS calculation, and so on. The method is still relevant and is used by many administrators...
