Watson
 IBM Research built a computer system able to compete with humans at the game of Jeopardy:
Human vs. Machine contest.
 Code-named “Watson,” Computer is designed to rival the human mind
 Answering questions in the Jeopardy! format poses a grand challenge in computer science:
– Broad range of topics , such as history, literature, politics, popular culture and science
– Nature of the clues, requires analyzing subtle meaning, irony, riddles and other complexities
 Based on the science of Question Answering (QA), differs from conventional search
 Critical for implementing useful business applications such as:
– Customer relationship management
– Regulatory compliance
– Help desk support
 Watson and Workload Optimized Systems
 Watson’s success in the Jeopardy! challenge is inspiring a new era of optimized systems design. Based on commercially
available IBM Power® 750 servers, Watson’s advances in deep analytics and its ability to process unstructured data and
interpret natural language will now be tailored to fit the requirements of new solutions in science, healthcare, financial services
and other industries. Download the white paper and read more about Watson and workload optimized system design.

PowerVM Virtualization

IBM Power Systems
100
Virtualization – a substitution process
Creates virtual resources from real resources.
Primarily accomplished with software and/or firmware.
Resources
Components with architected interfaces/functions.
Usually physical. May be centralized or distributed.
Examples: memory, disk drives, networks, servers.
Virtual Resources
 Substitutes for real resources: same interfaces/functions, different attributes.
 Often of part of the underlying resource, but may span multiple resources.
 Separates presentation of resources to users from actual resources
 Aggregates pools of resources for allocation to users as virtual resources

Virtualization
Roles:
Consolidations
Dynamic provisioning/hosting
Workload management
Workload isolation
Software release migration
Mixed production and test
Mixed OS types/releases
Reconfigurable clusters
Low-cost backup servers
Benefits:
Higher resource utilization
Greater usage flexibility
Improved workload QoS
Higher availability / security
Lower cost of availability
Lower management costs
Improved interoperability
Legacy compatibility
Investment protection
In the final analysis, the virtualization benefits take three forms:
• Reduced hardware costs
Higher physical resource utilization
Smaller footprints
• Improved flexibility and responsiveness
Virtual resources can be adjusted dynamically to meet new or changing needs
and to optimize service level achievement
Virtualization is a key enabler of on demand operating environments
• Reduced management costs
Fewer physical servers to manage
Many common management tasks become much easier
 However, server
virtualization
introduces some
complexity
and requires skills
 This partially offsets the
benefits, but the net gains
are generally substantial

Outlook:
• Bare metal hypervisors with high efficiency and availability will become dominant for servers
• Hosted hypervisors will be mainly for clients where host OS integration is important
• Hardware partitioning will die out as an approach
Server is subdivided into fractions
each of which can run an OS

Progressive Phases of IT Transformation
Virtualization and integration will be used to reduce IT complexity
and cost and to improve IT qualities (agility, resilience, security, …)
IT In The Future
IT Today
Workload optimized
systems and solutions
Lower IT Costs, Higher IT Quality
Consolidations
• Better hardware utilization
• Improved IT agility
• Lower power consumption
Pools
• Manageable like single systems
• Reduced scale-out complexity
• Lower operational expense
• Improved resilience / security
Clouds
• Utility model; self-service
• Lower cost; massive scalability
• Public, private, and hybrid

IBM Power Systems
113
REDUCE COST by consolidating with Power Systems
 Resource sharing
 Sharing system resources through virtualized
consolidation reduces unused system overhead
 Virtualized consolidated systems are evidenced by
high utilization rates
 High utilization means less hardware
 Environmentally friendly
 Less power and cooling is required
 Less floor space is required
 Fiscally responsible
 Fewer processor cores drives less software costs
 Newer systems are more reliable and less costly to
maintain than older systems
 Fewer systems translates to reduced people costs

IBM Power Systems
114
Why is scalability important?
 The #1 reason IT managers deploy virtualization solutions is workload
consolidation
– Put simply, the more workloads that can be encapsulated within VMs and combined
onto a single server, the higher the consolidation ratio and greater the cost
reduction
– The integrated combination of the POWER architecture and PowerVM makes
possible to achieve far higher consolidation ratios than scale-out scenarios

IBM Power Systems
116
Reduce cost with Active Memory Sharing (and/or Active
Memory Expansion)
 Dynamically adjusts memory available on a
physical system for multiple virtual images
based on their workload activity levels:
– Different workload peaks due to time zones
– Mixed workloads with different time of day
peaks (e.g. CRM by day, batch at night)
– Ideal for highly-consolidated workloads with
low or sporadic memory requirements
 Available with PowerVM Enterprise Edition
– Supports AIX®, IBM i and Linux workloads
 Blends Power Systems hardware, firmware
and software enhancements to optimize
resources
– Supports over-commitment of logical memory
 Systems built on the POWER7 processor can
use Active Memory Expansion to achieve
apparent memory of as much as 2X true

Reduce cost and complexity with Virtual LAN
 Virtual networking for server-to-server communication can sustain
performance while reducing network utilization and physical points-of-failure
 Removes the need for network adapters and switches for communication
between LPARs
 Can drastically improve network recovery in the event of a disaster – no
physical cables to re-connect or diagnose
Reduce network latency
Increase server network
throughput up to 3X!

AIX 7 -- The Future of UNIX
*All statements regarding IBM's future direction and intent are subject
to change or withdrawal without notice, and represent goals and objectives only.
Some features require the purchase of additional software components.

IBM Power Systems
131
AIX Workload Partitions (WPAR)
 WPARs are designed to save
administrator work by reducing
the number of AIX instances to
patch
 WPARs have much lower
memory resource requirements:
68 MB vs 1GB for an LPAR
 WPAR takes seconds to create
and LPARs minutes
 Application mobility much simpler
to organize than LPM
 Lots of WPARs on one AIX is
simpler to monitor and control
than monitoring across many
LPARs.
 Rapid cloning is easy and lets
you use "disposable images" -
simple to create, experiment and
throw away
Virtualized AIX operating system
environments within a single AIX
image
Each WPAR shares the single
AIX operating system
AIX 7 added the capability to run
AIX 5.2 in a WPAR*
Applications and users inside a
WPAR cannot affect resources
outside the WPAR*
Each WPAR can have a
regulated share of processor,
memory and other resources
Two types of WPAR
- System WPARs have separate
security and appear like a
completely separate OS
- Application WPARs are
manageability wrappers around
a single application
Top reasons to use WPARs
What is it?

– NPIV-like, but can work on any Fibre Channel adapter
– Adds support for Fibre Channel tape
 Kernel Extensions for WPARs
– Trusted kernel extensions may be loaded by the WPAR administrator
– Extensions can be only for one WPAR or for entire system
 Support for VIOS disks in WPARs
– VSCSI disks can be exported to a WPAR
– This feature also available in AIX 6 Technology Level 6
 Run AIX 5.2 inside of a Workload Partition
– Consolidate older environments on POWER7 processor-based systems
– Requires AIX 5.2 WPARs for AIX 7 – available separately from AIX 7

IBM Power Systems
133
