r Three-year cost of hardware
maintenance
r Three-year cost of support and
subscription for the software
In the cost comparison shown in
Figure 5 (left), the System z mainframebased solution has a 58 percent lower cost
than the Intel hypervisor-based solution.
Overall, the study demonstrates the
impact of various workload management
mechanisms when choosing hosting
platforms.

The Results Are In
Research demonstrates that System z
workload management is nearly perfect
when mixing workloads. Low-priority
workloads give up resources to highpriority ones when required, but soak up
unused resources when available. More
importantly, the performance of higherpriority workloads doesn’t degrade when
lower-priority loads are added.
In contrast, the common Intel
hypervisor platform is unable to maintain SLA of the high-priority workload
when a lower-priority workload is added.
This results in severe degradation in
throughput and response-time metrics
for the high-priority workload when
mixing workloads. In this case, the
only practical solution is to deploy the
various workloads into separate environments. Therefore, the need to maintain
multiple environments directly affects
the total cost of the solution. As the case
study shows, a System z solution can
cost much less than an Intel hypervisorbased solution.
