As a guideline, the following vCPU:pCPU ratios can be considered a good starting point for a design:
– 1:1 to 3:1 is not typically an issue
– With 3:1 to 5:1, you might begin to see performance degradation
– 6:1 or greater is often going to cause a significant problem for VM performance
IT seems “A” may be right answer…
Answer: D
Some respondents indicate that they have received guidance that suggests no more than a 1.5:1 vCPU to pCPU ratio, but guidance from industry experts suggests that vSphere real-world numbers are in the 10:1 to 15:1 range. Still others indicate that VMware itself has a recommended ratio range of 6:1 to 8:1.
