The Mega Trends
n The three iron laws of IT that drive infrastructure
n Cloud Computing as seen from above n Integrated Systems: why the infrastructure
of the future looks a lot like the infrastructure of the past!
Moore’s Law
n Massive growth in computation, dramatic decline in unit cost n Problem is no longer CPU power or processing costs
n Issues are power efficiency, utilisation and I/O performance
n Number of cores doubles every 18 months n 10 core x64 CPUs today n 200+ cores/blade enclosure n Tri-gate transistors, better power and performance
n Fortunately DBMS, App Server & Web Servers and Hypervisors already scale to 100’s of cores!
Server Virtualisation
n Exploits Moore's law n Drives server consolidation
n Improves utilization & power efficiently
n Leverage for HA, DR and CO n Then move to policy and automation
n Mainstream but 60% have not virtualised mission critical apps
n Licencing n vSphere 5.0 changes n Application licencing
n Oracle OVM

Database consolidation
n Another way to exploit Moore’s law n VMs vs. Instance vs. Schema
n O/S & DB version n Patching and upgrading n Workload compatibility n Capacity management
Shugart’s Law n Cost per bit halves every 18 months
n About 37% pa or 10% per quarter n Delaying 1 quarter can save you 10%
n Constrains storage capital costs n On a 4 year H/W lifecycle a flat budget
supports 60%pa data growth
n Has enabled massive storage growth but… n Management complexity n Performance issues
n 3TB SATA this year n How do you exploit large, slow, cheap drives n Performance becomes is an issue
n Oracle ASM
Disruption of Storage n Evolution of storage arrays
n Commodity hardware, i.e., x64 servers n SATA for capacity mixed with Flash Cache for perf n Deduplication & Snapshots for storage optimisation n Clustered architecture & virtual appliances
n Examples n HP Left Hand & VMware vSA n Oracle zFS fileservers n Oracle Exadata Storage for DB n IBM XIV
n Disrupts current vendors/market n Like M/F vs. UNIX/RISC vs. Wintel/Lintel n Look beyond traditional modular storage
Storage Virtualisation
n Network based storage virtualisation has limited adoption n Additional cost is a major barrier (4K-6K/TB?) n Need to be very, very large to justify cost/benefit
n Vendors: IBM (SVC), HP, EMC v-Plex n EMC new to this market the market with v-Plex
n Use cases n Mostly used for data migration (SVC) n Cloud providers with unpredictable workloads.
Gilder's Law
n Optical fiber bandwidth doubles every 12 months
n Is driving IT centralisation n Branch offices are next
n What impact will the NBN have on your WAN strategy?
n What every you believe about networking now will be wrong in 7 years
Converged Networking n Core FCoE & CEE standards ratified
n Major vendors have products n Dominant storage protocol in long-run
n Demand driven by workload density n Moore’s Law and Virtualisation
n Benefits n Lower capital costs from lower port,
switch and cabling requirements n Greater I/O flexibility from dynamic
sharing of a higher bandwidth, common transport layer
n Capacity can be optimised and used more effectively
n Barriers n Existing large scale investment in Fibre
Channel n Cuts across server, storage and
networks silos, potentially changes the roles and relationships of these teams.
n Use an incremental adoption strategy, n High density servers use a converged
network at the server edge. n Integrate into the existing FC &
Ethernet infrastructures n Displace FC switches over time
Cloud Computing
• Different ways of thinking about the cloud • How do clients view “The cloud”? • What does the business want
Cloud as Technology
• Virtual machines • Clusters • Multi-tenancy • Internet • Web Protocols
Its time to stop thinking about the Cloud as a technology
Cloud as Services
n What is the cloud? • IaaS • PaaS • SaaS • Public/private
Think about the Cloud as an aspiration to create a “better IT environment”
Cloud as Capabilities Self-Service
Cost Transparency
Capacity on Demand
Utility Pricing
Location & Device
Independence
Commodity pricing
Think about Cloud as new capabilities that are aligned to the business’ needs
The Cloud as a Journey
n Levels of capability • Where are you now? • Where do you need to be? • Strategy for getting there?
Think of the Cloud as a journey to these new capabilities. Where do I start and where do I stop?
What are clients thinking • The cloud is not clearly defined in
user’s minds • Each vendor defines it around
their own product sets
• It means very different things to different people • IaaS, SaaS, Public, Private etc
• Many business and IT people are uncomfortable with • Security, governance, compliance
& cost • Often this is perception, rather
than reality
Potential for significant misunderstandings between users, vendors and partners
What does the business want?
• They are interested in the benefits of the cloud not the technology, i.e., • A more agile, more efficient IT infrastructure • Increased robustness, i.e., HA, DR, Continuous
Operations • Transforming IT from a CapEx intensive fixed asset to a
OpEx based utility • Self-service, transparent pricing
Talk about Service Capabilities and Benefits, not Technology Features and Functions
The empire, long divided, must unite; long united, must divide. Thus it has ever been.
-- Three Kingdoms
Layered Components n Started in ‘80s with Open Systems n Layers defined by standards n Pros: Vendor competition drives
n Lower component cost n Innovation at each layer
n Drawbacks: IT becomes an SI! n Defines specs, n Integrates components, n Maintains integration across
disparate product lifecycles
System integration costs and times now outweigh the benefits of competition
Integrated Systems n Still use open standards and
commodity components n A “Systems Architecture”, not
just “Factory Integration” n Who can do this?
n IBM, HP, Dell & Oracle
n Who is at risk n Cisco, EMC, NetApp n All the niche component players
Get out of the SI business and buy end-to-end designs from a single trusted systems vendor

Barriers to moving to an Integrated Systems model
Existing IT org structure and the investment in IT skills and infrastructure will be the major adoption barriers

Two approaches to adoption Mandate
n Smaller organisations n CIO mandates the use of
Integrated Systems n Triggered by refresh of
main Infrastructure n Staff skills less of an issue
Seeding n Larger organisations n CIO seeds a “hot house”
to develop new capability n Leaves “Old IT” alone n Steer specific new project
to the hot house
The key question becomes “when and how”. Because …

Questions 1. Transition from one model to the other is always the most difficult as it
is a 'sunk cost' While Integrated system may be better overall, the huge existing investment means transition costs are a major barrier.
2. What is the current take up/trend of the major Australian FI's around Oracle's Integrated System model
3. With an integrated model won't we loss some of the functionality offered by the Best-of-Breed solutions?
4. How would you rate the ease of upgrading each of the different stacks as the technologies on each stack improve over time?
5. Integration with other vendor technologies and ability to use historical infrastructure
6. How involved do you get when choosing an integrated solution. How much control do you give away ? Main concern is poor Oracle support
Questions 1. What type of resources are needed to support the Integrated
systems model 2. Should Customers be more concerned about vendor lock in when
following an integrated systems model? If not, why not? 3. By removing the Design and Integration layers of the model, how
can we ensure the technologies align with business requirements? Is there an expectation that the business will follow the technology?
4. What plans does Oracle have to eliminate complexity of licensing and provide financial incentive to leverage an integrated stack ? Why the Oracle licencing model is so complex? Why is Oracle so expensive?
5. Is going Oracle to support small business or target Corporate clients only?
