1) Advanced POWER Virtualization (APV) is an optionally orderable feature on IBM System p, 2) Partition Load Manager (PLM) is not supported on OpenPower / Linux Partitions, 3) Only available on select models, 4) “Business Case for IBM System p5 Virtualization,” Economic Benefits of IT Simplification. International Technology Group, 02/10/2006. Study methodology: Companies in financial services, manufacturing and retail with $15 Billion+ revenues and total 200,000+ employees focusing on UNIX® large enterprise environments with multiple, broad-ranging applications. Study compared the cost of the company's workload running on multiple vendor servers and employing minimal virtualization to the cost of the company's workload running on the p5-510, 550, 570, 590 and 595 – all using Advanced POWER Virtualization [APV]. APV is standard on System p5 590 and 595. Other System p servers have the option to add APV except the System p5 185. This cost analysis was performed for financial services, manufacturing and retail example environments with an overall average savings of up to 62% in TCO savings by virtualizing and consolidating on the System p servers. For further information, see the white paper at: http://www-03.ibm.com/systems/p/library /consult/ itg_p5virtualization.pdf Total Cost of Ownership may not be reduced in each consolidation case. TCO depends on the specific customer environment, the existing environments and staff, and the consolidation potential. , 5) IBM sales Statistics, *All statements regarding IBM future directions and intent are subject to change or withdrawal without notice and represent goals and objectives only.

POWER6 Virtualization Enhancements

Partition Mobility: Active and Inactive LPARs Active Partition Mobility Active Partition Migration is the actual movement of a running LPAR from one physical machine to another without disrupting* the operation of the OS and applications running in that LPAR. Applicability Workload consolidation (e.g. many to one) Workload balancing (e.g. move to larger system) Planned CEC outages for maintenance/upgrades Impending CEC outages (e.g. hardware warning received)

Inactive Partition Mobility Inactive Partition Migration transfers a partition that is logically ‘powered off’ (not running) from one system to another.

Partition Mobility supported on POWER6™ AIX 5.3, AIX 6.1 and Linux 41

What Are Workload Partitions? Separate regions of application space within a single AIX image • Partitioned system capacity • Each Workload Partition obtains a regulated share of the processor and memory resources • Each Workload Partition has separate network and filesystems and many system services (e.g. telnetd, etc.) • Separate Administrative control • Each partition is a separate administrative and security domain • Shared system resources • I/O Devices • Processor • Operating system • Shared Library and Text

Workload Partitions

➼ ➼

Consolidations: Virtual Servers or Application Regions? Goal: Consolidation

Partition Mobility (Part of APV) Each Application Has Its Own AIX LPAR, Multiple LPARs Per Server

Each Application Is In Its Own AIX WPAR, Multiple WPARs Per AIX

Fault Isolation

Full isolation: OS faults will only impact the specific LPAR

Limited isolation: OS faults will bring down all regions, but happen infrequently

Security Isolation

Complete isolation between OSes â&#x20AC;&#x201C; shared nothing

Only user space level isolation; kernel level is still exposed

OS levels

Different OS levels in LPARs possible

Has to be the same across all WPARs

OS Service/Fix Level

OS service fixes can be applied to individual LPAR OS images

OS service fixes affect all WPARs, negatively impacting multi application - OS dependency

ISV Software Cost

ISVs will count only the number of processors in LPAR

Many ISVs price based on number of CPUs, they will count all processors in OS image

Efficiency

Good, but little sharing of OS resources leads to lower efficiency than with region approach

Very good, due to extensive sharing of OS resources such as code or text

System Admin costs

System admin costs donâ&#x20AC;&#x2122;t go up linearly per OS image as cluster sys mgmt tools lower costs for managing multiple OS images

TCO analysis based on number of OS images would favor regions, although in reality system administration costs will shift to per region level

Resource Granularity

Fine grained

Very fine grained

Mobility

Active LPAR movement in 2007 Requires POWER6

Active WPAR movement in 2007 Requires AIX 5.4 (Can run on P4 and up)

Each approach comes with pros and cons, so the choice depends on customer needs and preferences. 48
