Advanced POWER Virtualization on IBM System p

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.

“The centralized, virtualized CRM environment powered by eServer p5 [System p] servers provides superior infrastructure support, improved efficiency in our people and systems and truly optimized operations.”6

Help improve application performance…and increase business responsiveness

These companies reported increased application performance with IBM technologies including System p virtualization:

KCA DEUTAG: Reduced SAP reporting from 2.5 hours to 20 minutes1

Alstrom: Doubled SAP transactions per second2

Sinopec: Completed ERP reporting in 30-35% less time3

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)

Active Partition Mobility Active Partition Migration is the actual movement of a running LPAR from one

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.

• Each Workload Partition has separate network and filesystems and many system services (e.g. telnetd, etc.)

Consolidations: Virtual Servers or Application Regions?

Goal: ConsolidationPartition 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 IsolationFull 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 – shared nothingOnly 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 CostISVs will count only the number of processorsin 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 costsSystem admin costs don’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

MobilityActive LPAR movement in 2007Requires POWER6

Active WPAR movement in 2007Requires 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.
