There are several factors that must be considered when calculating CPU resources' requirements, such as the amount of CPU resources required to support the current workloads, the amount of CPU resources required to support future growth, and the maximum CPU utilization threshold.
The following discovery information from Chapter 3, The Design Factors, will be used to calculate the CPU requirements:
Currently, there are 100 physical servers, each hosting a single application. Each application services 10 customers.
The business expects to add 50 new customers over the next year.
Support growth over the next 5 years.
Each application server is configured with two dual core 2.7 GHz processors. The peak usage of a single application server is approximately 10% of the total or approximately 1 GHz.
Determine the amount of CPU resources required to support the current workloads:
Number of Workloads x CPU Speed in MHz or GHz = Current CPU Resources Required...
