Common misconception on infrastructures
Following points are gathered from the Microsoft training,
It includes some best practices also

1. Virtualization may be the smartest way of handling your infrastructures.
But having DAtabase server on virtualization seriously affect the performance of AX system. It reduces 14.5 % performance down compared to physical servers.

2. Putting more Memory and Processin...g power Wouldnt help if you dont know the sizing   guidelines
For example,
AOS Server Sizing,
5K Lines Per Hour Per Core (usually 4 to 12 core box)
2 GB Memory for Each Core (usually 4 to 8 GB per AOS instance)
User Concurrency is a good Marker. Based on Transaction Complexity, between 50 Users Per Core to 150 Users Per Core (average of 60)

3. Database Thumb rule is 2 to 6 GB memory for each CPU core. Next you have to set SQL Server maximum server memory correctly. Always leave a percentage for OS and other services running on the box
