IBM Power Systems with PowerVM technology
IBM Power Systems — with the superior performance of PowerVM virtualization technology and with features such as reliability, security, high availability, and resiliency — are well positioned for cloud computing and smarter planet solutions today and in the future.
Virtualization has become a pervasive means of consolidating workloads on fewer systems, controlling server sprawl and minimizing costs. With IBM Power Systems and PowerVM virtualization technologies, organizations can achieve virtualization with outstanding performance. IBM Power Systems with PowerVM technology demonstrated superior performance and greater efficiency in using system capacity at higher utilization, as well as at higher resource contention (over-commit levels), and superior scaling with higher throughput performance.
Feature at a glance :
In summary, the study has shown that IBM POWER7 systems and PowerVM technology have demonstrated:
- Higher throughput performance for both AIM7 and TPoX benchmarks, ranging from 50 percent better to as much as 200 percent better.
- Higher efficiency in resource over-commit mode (higher consolidation ratio), with the response time on PowerVM virtualization technology two to six times shorter, compared to response time for VMware vSphere 4.1 update 1, as the number of VMs scaled from five to 40 VMs.
- Higher processor affinity by default (40 VMs sharing eight cores), retaining 2.3 times better performance than HP Intel/VMware vSphere 4.1 update 1 technologies, even with reconfiguration using CPU affinity (VMware Scheduling Affinity group) on VMware vSphere 4.1 update 1.
- Efficient leveraging of maximum configured processor capacity.
- Accurate accounting of resource usage within a VM.
- Tighter integration across system, hypervisor, and guest OS.
- Better performance overall than Intel Xeon 7560 /VMware vSphere 4.1 update 1.
The charts that follow summarize the results :
The first — the AIM7 performance benchmark 32-core VM scaling (scale-up) results — shows that PowerVM on POWER7 delivers superior scale-up efficiency that outperforms VMware vSphere 4.1 update 1 by up to 115 percent while running the same Linux workloads and virtualized resources.

32 VM Scale-out on 32 cores
In fact, PowerVM on POWER7 retains its superiority even configured with an additional
virtual CPU per VM.
The second — the TPOX performance benchmark 5 VM per core (scale-out) — shows that PowerVM on POWER7 delivers robust scale-out efficiency that outperforms VMware vSphere 4.1 update 1 by up to 201 percent while running the same workloads and virtualized resources.

PowerVM maximizes workload performance and system resources while running
multiple virtual machines on a core better than does VMware vSphere 4.1 update 1.
