IBM PowerVM® delivers industrial-strength virtualization for AIX and Linux environments on POWER processor-based systems. It has been enhanced with a virtualization-oriented performance monitor, and performance statistics are available through the HMC. These performance statistics can be used to understand the workload characteristics and to prepare for capacity planning.

Mobile application platform

Speeds development and management of mobile applications. It includes a development environment, runtime middleware, a private enterprise application store and a management and analytics console to: Co-locate applications on a scalable server; streamline access to data and applications with virtual networking; accelerate deployment; and reduce overhead by using existing production and disaster recovery infrastructure.

Included analytics software

Includes: IBM Solution for Analytics Power Systems Edition—a flexible, integrated solution that provides options to preload and configure one or more IBM analytics applications with data warehouse acceleration. It delivers IBM Cognos® Business Intelligence capabilities. IBM BLU Acceleration Power Systems Edition—IBM Db2® dynamic in-memory, columnar data warehouse acceleration that enables you to use both row-based and columnar data storage simultaneously.

Memory subsystem RAS

Memory has error detection and correction circuitry so that the failure of any one specific memory module within an ECC can be corrected absent of any other fault. A spare DRAM per rank on each memory port provides for dynamic DRAM device replacement during runtime operation. Dynamic lane sparing on the DMI link allows for repair of a faulty data lane.

Processor availability functions

The POWER9 processor performs processor instruction retry for some transient errors and alternate processor recovery for a number of core-related faults. This significantly reduces exposure to both hard (logic) and soft (transient) errors in the processor core.

Partition availability priority

In the PowerVM environment, if an alternate processor recovery event requires spare processor resources in order to protect a workload, when no other means of obtaining the spare resources is available, the system will determine which partition has the lowest priority and attempt to claim the needed resource to allow that capacity to be first obtained from, for example, a test partition instead of a financial accounting system.

Cache availability

The L2 and L3 caches in the POWER9 processor and L4 cache in the memory buffer chip are protected with double-bit detect, single-bit correct error detection code (ECC). In addition, a threshold of correctable errors detected on cache lines can result in the data in the cache lines being purged and the cache lines removed from further operation without requiring a reboot in the PowerVM environment.

Live partition mobility

With Live Partition Mobility, users can migrate an AIX, Linux, or IBM i partition running on one POWER partition system to another POWER system without disrupting services. The migration transfers the entire system environment, including processor state, memory, attached virtual devices and connected users. It provides continuous operating system and application availability during planned partition outages for repair of hardware and firmware faults.

Service processor

The service processor provides the capability to diagnose, check the status and sense the operational conditions of a system. It runs on its own power boundary and does not require resources from a system processor to be operational.
