New Powervm Version 2.2.2 Features - IBM Power 750 Technical Overview And Introduction

3.6 New PowerVM Version 2.2.2 features

Power Systems server coupled with PowerVM technology are designed to help clients build a
dynamic infrastructure, reducing costs, managing risk, and improving services levels.
IBM PowerVM V2.2.2 includes VIOS 2.2.2.1-FP26, HMC V7R7.6 and Power Systems
firmware level 760 and contains the following enhancements for managing a PowerVM
virtualization environment:
Supports for up to 20 partitions per processor, doubling the number of partitions supported
per processor. This provides additional flexibility by reducing the minimum processor
entitlement to 5% of a processor.
Dynamically add virtual I/O adapters to or dynamically remove them from a Virtual I/O
Server partition.
The HMC V7R7.6, or later, automatically runs the add or remove command (cfgdev or
rmdev) on the Virtual I/O Server for the user. Prior to this enhancement, the user had to
manually run these commands on the Virtual I/O Server.
Ability for the user to specify the destination Fibre Channel port for any or all virtual Fibre
Channel adapters.
Improved Virtual I/O Server setup, tuning, and validation using the Runtime Expert.
Live Partition Mobility supports up to 16 concurrent LPM activities.
Shared Storage Pools create pools of storage for virtualized workloads, and can improve
storage utilization, simplify administration, and reduce SAN infrastructure costs. The
enhancements capabilities enable 16 nodes to participate in a Shared Pool configuration,
which can improve efficiency, agility, scalability, flexibility, and availability.
Shared Storage Pools flexibility and availability improvements include the following items:
– IPv6 and VLAN tagging (IEEE 802.1Q) support for intermodal shared storage pools
communication.
– Cluster reliability and availability improvements.
– Improved storage utilization statistics and reporting.
– Nondisruptive rolling upgrades for applying service.
– Advanced features that accelerate partition deployment, optimize storage utilization,
and improve availability through automation.
New VIOS Performance Advisor analyzes Virtual I/O Server performance, and makes
recommendations for performance optimization.
PowerVM has the following new advanced features enabled by VMControl that accelerate
partition deployment, optimize storage utilization and improve availability through
automation.
– Linked clones allow for sharing of partition images, which greatly accelerates partition
deployment and reduces the storage usage.
– System pool management for IBM workload provides increased flexibility and resource
utilization.
