IBM’s 39-year history of leadership in virtualization:

5 IBM’s 39-year history of leadership in virtualization IBM develops hypervisor that would become VM on the mainframe IBM announces first machines to do physical partitioning IBM announces LPAR on the mainframe POWER LPAR design begins 1967 1973 1987 IBM introduces LPAR in POWER4™ based systems with AIX 5L™ Advanced POWER™ Virtualization ships 2004 2001 1997 Timeline reference http://www.levenez.com/unix/history.html#01 Customer quote source: rku.it case study published at http://www.ibm.com/software/success/cssdb.nsf/CS/JSTS-6KXPPG?OpenDocument&Site=eserverpseries “In our opinion, they [System p servers] bring mainframe-quality virtualization capabilities to the world of AIX®.” - Ulrich Klenke, CIO, rku.it January 2006 Advanced POWER Virtualization on IBM System p™ servers


6 IBM APV Benefits Can help lower the cost of existing infrastructure Can increase business flexibility and reduce the complexity to grow your infrastructure Deployed in production by a significant number of System p clients 5 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.

40 POWER6 Virtualization Enhancements

Partition Mobility: Active and Inactive LPARs:

41 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


42 Move active Micro-Partitions between systems Reduce the impact of planned outages Relocate workloads to enable growth Provision new technology with no disruption to service Virtualized SAN and Network Infrastructure IBM System p – Partition Mobility https://www.pass4sureexam.com/C4040-252.html

What Are Workload Partitions?:

43 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 Partition A AIX 6.1 Image Workload Partition C Workload Partition B Workload Partition D Workload Partition E Separate regions of application space within a single AIX image What Are Workload Partitions? https://www.pass4sureexam.com/C4040-252.html

What is AIX Application Mobility?:

44 Workload Partition QA AIX # 2 Workload Partition Data Mining What is AIX Application Mobility? Workload Partition Database Workload Partition Web AIX # 1 Application Partition Dev The ability to move a Workload Partition from one server to another Provides outage avoidance and multi-system workload balancing Workload Partition ERP Policy based automation can provide more efficient resource usage Workload Partition Manager Policy Workload Partition Billing

When to use Workload Partitions:

47 When to use Workload Partitions Requirement MicroPartitions Workload Partitions Hardware enforced Isolation Minimal number of AIX images Server Consolidation Greatest Flexibility Cross system workload management Move workload between systems https://www.pass4sureexam.com/C4040-252.html

Consolidations: Virtual Servers or Application Regions? :

48 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 – 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 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 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. https://www.pass4sureexam.com/C4040-252.html
