Virtualization Foundation Solutions
Based on the POWER® processor, Power Systems servers are architected to achieve maximum performance and efficiency for both the system and its virtual machines. Intelligent work-load based resource allocation with dynamic processor thread switching and logical memory expansion deliver optimal performance for critical Cloud services.
Power Systems provide a choice of hypervisor with IBM’s own PowerVM® or the open source PowerKVM. PowerVM makes efficient use of system resources and imposes a negligible impact on performance because PowerVM is built directly into the firmware of all Power Systems, as opposed to x86-based virtualization products which are typically third-party software add-ons. Being part of the firmware also means PowerVM is secure by design, with zero reported Common Vulnerabilities Exposures for the PowerVM hypervisor (versus more than 200 reported for VMware) in the US Government NIST Database.1
PowerKVM presents a choice for customers looking for an open source virtualization solution for Linux on Power Systems built on POWER8 technology. PowerKVM provides support for Red Hat® Enterprise Linux, SUSE® Linux Enterprise Server, and Ubuntu® guests and is optimized for the Power Systems platform with support for processor and memory sharing over-commit for higher utilization, dynamic addition and removal of virtual devices, and live VM migration.
Advanced virtualization management is available with PowerVC (Virtualization Center). Built on OpenStack, it allows Power Systems cloud infrastructure to plug into a broad array of management solutions. It also enables high utilization of Power Systems with its advanced placement algorithms for VMs and easy to use interface that helps administrators quickly react to changing business demands for IBM AIX®, IBM i, or Linux environments.
For truly elastic, pay-per-use cloud like capabilities, Power Systems provide Capacity on Demand which enables additional memory and compute resources to handle temporary spikes in system usage.
With platform management technologies on Power Systems, businesses have the tools to automatically deploy, optimize, and maintain these systems at maximum effectiveness, energy efficiency, and cost control.
