- What's new in PowerVM Editions
Read about new or changed information in the PowerVM Editions topic collection since the previous update. - PowerVM Editions overview
Learn about the editions of the PowerVM Editions hardware feature. - Entering a PowerVM Editions activation code
You can enter the activation code for PowerVM Editions by using the Integrated Virtualization Manager, or the Hardware Management Console (HMC). A Trial Live Partition Mobility code can be entered only by using the HMC. - Power Integrated Facility for Linux (IFL)
Power Integrated Facility for Linux (IFL) is an optional lower cost per processor core activation for Linux-only workloads on Power Systems. - Micro-Partitioning technology
When you enable the Micro-Partitioning® technology, you can configure multiple partitions to share system processing power. - Active Memory Sharing
When you enable the PowerVM Active Memory™ Sharing technology, you can configure multiple partitions to share system memory. - Virtual I/O Server
Manage the Virtual I/O Server and client partitions by using the Hardware Management Console (HMC), and the Virtual I/O Server command-line interface. - Integrated Virtualization Manager
You can use the Integrated Virtualization Manager (IVM), a component of the PowerVM Editions hardware feature, to manage your Virtual I/O Server and client partitions. - Live Partition Mobility
Live Partition Mobility, a component of the PowerVM Enterprise Edition hardware feature, provides the ability to move AIX® and Linux partitions from one system to another. The mobility process transfers the system environment including the processor state, memory, attached virtual devices, and connected users. - Virtual I/O Server and Integrated Virtualization Manager commands
Find a list of command reference information for the Virtual I/O Server (VIOS) and the IVM. - Virtual I/O Server release notes
Find a list of release notes for different versions of the VIOS. - Thin provisioning
Thin provisioning helps reduce the amount of unused storage allocated to applications or users. - Thick provisioning
Thick provisioning helps reserve storage space for virtual disks, thus ensuring that there are no failures because of lack of storage space. - Virtual fibre channel (NPIV)
With N_Port ID Virtualization (NPIV), you can configure the managed system so that multiple partitions can access independent physical storage through the same physical Fibre Channel adapter. - Shared storage pools
A shared storage pool provides distributed storage access to all VIOS partitions in the cluster. Each cluster consists of one or more networked VIOS partitions. - Shared processors pools
You can assign priorities to partitions and the hypervisor allocates processing power as needed by the applications. This feature allows for automatic nondisruptive balancing of processing power between partitions assigned to shared pools resulting in increased throughput and the potential to reduce processor-based software licensing costs. This feature is supported on POWER6® and POWER7® processor-based servers. - Partition Suspend/Resume
A running AIX, Linux, or IBM® i partition can be suspended along with its operating system and applications. When a partition is suspended, the state of the partition is saved on persistent storage, and the server resources that were in use by that partition are made available for use by other partitions. At a later time, the operation of the suspended partition and its applications can be resumed. 
PowerSC - Trusted Boot
Trusted Boot is a feature of PowerSC and you can enable Trusted Boot in PowerVM. You can use the Trusted Boot feature to confirm whether the operating system running on a partition has booted in a known and trusted state. Trusted Boot uses the Virtual Trusted Platform Module (VTPM) software implementation on an AIX partition.- PowerSC - Trusted Firewall
Trusted Firewall is a feature of PowerSC and you can enable Trusted Firewall in PowerVM. You can use the Trusted Firewall feature to provide a virtual firewall that allows network filtering and control within the local server. The virtual firewall improves performance and reduces the consumption of network resources by allowing direct and secure network traffic between partitions that are present on different VLANs of the same server. - PowerVP Overview
Power Virtualization Performance (PowerVP) is a performance monitoring solution that provides detailed and real-time information about virtualized workloads that are running on Power Systems. You can use PowerVP to understand how virtual workloads use resources, to analyze performance bottlenecks, and to make informed choices about resource allocation and virtualized machine placement. - Single root I/O virtualization
Single root I/O virtualization (SR-IOV) is a Peripheral component interconnect express (PCIe) standard architecture that define extensions to PCIe specifications to enable multiple partitions running simultaneously within a system to share PCIe devices. The architecture define virtual replicas of PCI functions known as virtual functions (VF). A partition can connect directly to an SR-IOV adapter VF without going through a virtual intermediary (VI) such as a POWER Hypervisor™ or Virtual I/O Server. This provides for a low latency and lower CPU utilization alternative by avoiding a VI. - Remote restart
Remote restart is a high availability option for logical partitions. When an error causes a server outage, a partition that is configured with the remote restart capability can be restarted on a different physical server. Sometimes, it might take longer to start the server, in which case the remote restart feature can be used for faster reprovisioning of the partition. This operation completes faster as compared to restarting the server that failed and then restarting the partition. - Virtual Network Interface Controller adapter
A logical partition to which single root I/O virtualization (SR-IOV) logical ports that are assigned cannot be migrated. To overcome this limitation, a virtual Network Interface Controller (vNIC) can be assigned to a logical partition. A vNIC is a type of virtual adapter that can be configured on client logical partitions to provide a network interface. Each vNIC client adapter is backed by an SR-IOV logical port that is owned by the Virtual I/O Server (VIOS).
