Tier Size Determination Star
Student Project Tier size forms the basis of calculation of many
cost factors Star Student Project such as H/W, S/W, and power
costs. We define a vector Star Student Project whose ith
element si denotes the number of servers for the tier Star Student
Project i of the multitiered application as is the
Peak-to-Average ratio Star Student Project the range of years
in the ith refresh Star Student Project cycle, and the vector
R the per-tier marginal capacity in request/second Star Student
Project of the reference servers we obtained from profiling as
described in Star Student Project is multiplied to adjust the
current average workload to the peak workload.
