PowerVM™ Virtualization with IBM Power Servers The IBM Power system are designed to handle consolidation projects of all different sizes, leveraging virtualization technology to drive multiple operating systems, business applications, and other workloads to run on a single, larger system designed to save costs by maximizing utilization, which in turn reduces the total cost of ownership, including maintenance and support contracts, administrative overhead, and power and cooling costs. All IBM Power Systems can run mixed workloads simultaneously on Linux, AIX, and IBM i (formerly i5/OS).
IBM’s new POWER6 technology includes a wide variety of virtualization technologies. POWER Hypervisor™ comes standard with all the new Power Servers, and includes well-established virtualization technologies designed to enable consolidation of multiple workloads, reducing TCO and maximizing flexibility.
Some of the advantages of virtualization include:
All of IBM’s Power servers with POWER6 processors includes the POWER Hypervisor technology. This virtualization technology enables logical partitioning (LPAR), which allows resources to be pooled and optimized across multiple operating environments and application workloads.
Dynamic LPAR enables LPAR technology to pool resources across multiple application environments, which the system automatically adjusts by provisioning resources from an idle partition to another partition experiencing higher workload demands.
Virtual LAN is a technology included in the Hypervisor which enables high-speed memory-to-memory communications between partitions. This allows multiple communication paths to be set for various TCP/IP applications.
Partitions can be utilized for testing and application development with its advanced partition isolation and security features.
PowerVM Express Edition is an optional component available for the Power 520 Express and Power 550 Express models, and increases the virtualization capabilities available. With PowerVM Express Edition, up to three partitions can be enabled on the server, and the disk and optical devices can be virtualized with VIOS (virtual I/O server) to increase the types of resources that can be shared across your system, and enables fault avoidance of I/O devices.
Virtual I/O server (VIOS) enables the sharing of virtual SCSI and virtual networking resources between LPARs. This eliminates the need for dedicated network adapters, disk adapters, and disk drives for each partition.
PowerVM Lx86 enables the dynamic execution of x86 instructions on Power servers, and then caching those instructions to optimize performance, and enable mapping of x86 Linux system calls to Linux on Power system calls. This enables almost all x86 Linux applications to run on Power systems.
Shared Processor Pool enhances administration of your virtualized environment on the Power systems by enabling the setting of prioritization of partitions, and allowing to Hypervisor to automate allocation processing power according to these prioritization levels.
The Integrated Virtualization Manager (IVM) featured in the Express Edition of PowerVM is a browser-based, point-and-click interface that simplifies the administration of your consolidated workloads. Create partitions and manage virtual storage and Ethernet resources, create and manage serviceable events via Service Focal Point, and view application logs and device inventory with this integrated management software.
The PowerVM Standard Edition includes all of the features of the PowerVM Express Edition, including VIOS with IVM, Lx86, and enhanced the granularity of resources that partitions can be provisioned, with Micro-Partitioning. Micro-partitioning enables up to 10 micro-partitions to be setup for each processor.
The Shared Processor Pool feature included with PowerVM Express Edition is enhanced in this Standard Edition with Multiple Shared Processor Pools. This feature enables non-disruptive balancing of processing power between partitions within shared pools of processing resources.
PowerVM Standard Edition includes a feature called Shared Dedicated Capacity, which helps to further increase performance and server utilization. With this feature, spare CPU cycles can be temporarily provisioned from dedicated processor partitions to Shared Processor Pools. The dedicated processor partition maintains priority over the resource for dedicated CPU cycles, enabling mission-critical workloads to maintain required performance levels as needed.
PowerVM Enterprise Edition is new, and only available on IBM’s new Power6 systems. Building on the virtualization technologies provided via PowerVM Express and Standard Editions, the Enterprise Edition of PowerVM and includes a new capability called Live Partition Mobility (LPM).
LPM maximizes the availability and resiliency of your virtualized environments and workloads by enabling the transparent migration of a running partition from one physical server to another. By being able to move a partition from one physical server to another without application downtime, planned downtime as a result of system maintenance, provisioning, or workload management can be virtually eliminated.
