How it works…

To calculate the amount of memory required to support the current workloads, the following formula is used:

Number of Workloads x Memory Usage = Current Memory Required
100 x 5.2 GB = 520 GB

The memory overhead of a virtual machine must also be accounted for when calculating memory requirements. The amount of memory required for an overhead depends on the configuration of the virtual machine.

The number of vCPUs allocated to the virtual machine, the amount of memory allocated to the virtual machine, and the virtual hardware configured for the virtual machine, will all have an impact on the amount of memory required for overhead:

Memory overhead example

Typically, the memory overhead required for a virtual machine is between ...
