IBM Powervm Lx86 Expands the Ability of IBM System P and Bladecenter Servers to Run X86 Linux Applications
IBM Canada Ltd. Announcement A08-0079, dated January 29, 2008 IBM PowerVM Lx86 expands the ability of IBM System p and BladeCenter servers to run x86 Linux applications Reference information ............................... 2 At a glance PowerVM Lx86, a standard feature of all PowerVM Editions, is available at no additional charge to support the installation and running of most 32-bit Linux on x86 applications1 on any System p model with IBM POWER5, POWER5+, or POWER6 technology. PowerVM Lx86: • Creates a Linux on x86 application environment running on Linux on System p servers by dynamically translating and mapping Linux on x86 instructions to POWER5, POWER5+, and POWER6 processors • Requires no native porting or application upgrade for supported applications Overview IBM is offering new and expanded options for POWER5™, POWER5+™, and POWER6™ processor-based System p™ servers so that clients can run x86 Linux™ applications that are not available as a native port on an IBM POWER™ platform running Linux. This enables clients to take advantage of the feature-rich IBM PowerVM Virtualization (formerly called System p Virtualization), high performance, and superb Reliability, Availability, and Serviceability (RAS) features available with System p and BladeCenter® servers. The PowerVM Lx86 feature expands the capabilities of POWER5, POWER5+, and POWER6 processor-based System p servers and PowerPC® and POWER6 processor-based blade servers to install and run most x86 Linux applications1. This new feature creates a virtual x86 Linux environment that will dynamically translate x86 instructions to POWER instructions and cache them to enhance performance, as well as map Linux on Intel® system calls to Linux on POWER system calls. -
A Comparison of Powervm and X86-Based Virtualization Performance
A Comparison of PowerVM and x86-Based Virtualization Performance October 20, 2009 Elisabeth Stahl, Mala Anand IBM Systems and Technology Group IBM PowerVM Virtualization Virtualization technologies allow IT organizations to consolidate workloads running on multiple operating systems and software stacks and allocate platform resources dynamically to meet specific business and application requirements. Leadership virtualization has become the key technology to efficiently deploy servers in enterprise data centers to drive down costs and become the foundation for server pools and cloud computing technology. Therefore, the performance of this foundation technology is critical for the success of server pools and cloud computing. Virtualization may be employed to: • Consolidate multiple environments, including underutilized servers and systems with varied and dynamic resource requirements • Grow and shrink resources dynamically, derive energy efficiency, save space, and optimize resource utilization • Deploy new workloads through provisioning virtual machines or new systems rapidly to meet changing business demands • Develop and test applications in secure, independent domains while production can be isolated to its own domain on the same system • Transfer live workloads to support server migrations, balancing system load, or to avoid planned downtime • Control server sprawl and thereby reduce system management costs The latest advances in IBM® PowerVM™ offer broader platform support, greater scalability, higher efficiency in resource utilization, and more flexibility and robust heterogeneous server management than ever before. This paper will discuss the advantages of virtualization, highlight IBM PowerVM, and analyze the performance of virtualization technologies using industry-standard benchmarks. PowerVM With IBM Power™ Systems and IBM PowerVM virtualization technologies, an organization can consolidate applications and servers by using partitioning and virtualized system resources to provide a more flexible, dynamic IT infrastructure. -
Migrating Linux Applications from X86 to IBM Power Systems a Discussion of Best Practices
IBM Systems and Technology Computer Services Technical White Paper Migrating Linux applications from x86 to IBM Power Systems A discussion of best practices Executive summary Contents With IBM® Power Systems™ servers and blades based on the IBM POWER® processor architecture, IBM has significantly elevated 1 Executive summary system performance, throughput and resiliency. These servers are capable of running your choice of operating systems (Linux, IBM AIX® and 2 Best practices for workload IBM i) in whatever combination you choose. Most importantly, the new selection architecture also integrates IBM PowerVM® virtualization to provide 6 Best practices during extreme scalability, flexibility and robustness.1 As a result, enterprise workload migration workloads deployed in PowerVM virtual machines (VMs) not only run faster on POWER-based platforms, but they can also scale further and 6 Capabilities be optimized more efficiently. 6 Valuable intellectual property PowerVM is a complete virtualization solution that is integrated and 10 Conclusion packaged with Power Systems. This is a very robust implementation of virtualization developed by IBM, based on best practices learned over the course of four decades of experience with the IBM mainframe. With each new Power Systems generation, IBM continues to grow its virtualization offerings beyond just the hypervisor, using features such as Live Partition Mobility and Active Memory Sharing. Reducing costs, improving service and managing risk are three focus areas virtualization customers are interested
