HP Virtualization Manager and HP Capacity Advisor: an introduction

Table 18-1 lists the workloads to be consolidated in this example scenario. The workloads in
this example have been chosen for illustration purposes. In a real-world situation, it would be
unlikely for the payroll, web, and backup workloads to be candidates for consolidation on the
same system because of their unrelated business purposes. Nevertheless, these workloads have
characteristics that are important to understand from a capacity-planning perspective and re-
sult in an insightful example.
As shown in Table 18-1, all of the workloads are hosted on separate nPartitions that contain
four CPUs and 8 GB of memory. The web workload is the primary web portal for the work-
group. This workload has cyclical usage patterns that are similar each day of the week and from
one week to the next. The second workload, payroll, runs on a biweekly basis. Finally, the backup
workload runs every night and has a predictable daily usage pattern. The table also represents
the expected growth in each of the workloads over the next year. This information will be used
to adjust the forecast for each workload.
