One of the challenges in provisioning a WSC is determining the proper power load, given the facility size. As described in the chapter, nameplate power is often a peak value that is rarely encountered.

a. Estimate how the per-server TCO changes if the nameplate server power is 200 W and the cost is $3000.

b. Also consider a higher power, but cheaper server option whose power is 300 W and costs $2000.

c. How does the per-server TCO change if the actual average power usage of the servers is only 70% of the nameplate power?
