Memory calculations

Based on the previous example, 25 VMs can be deployed per compute node. Memory sizing is also important to avoid making unreasonable resource allocations.

Let's make an assumption list (keep in mind that it always depends on your budget and needs):

• 2 GB RAM per VM
• 8 GB RAM maximum dynamic allocations per VM
• Compute nodes supporting slots of: 2, 4, 8, and 16 GB sticks
• RAM available per compute node:

8 * 25 = 200 GB

Considering the number of sticks supported by your server, you will need around 256 GB installed. Therefore, the total number of RAM sticks installed can be calculated in the following way:

Total available RAM / MAX Available RAM-Stick size

256 / 16 = 16
