Enterprise Linux

“Today Linux has become the hottest thing in corporate America since e-mail…For some companies, the gains from converting are so large that CIOs get giddy talking about it.”

business landscape
Business Landscape
  • Customers require more ROI than their existing investments
  • Must provide more scalable, available solutions and yet REDUCE costs
  • Support and maintenance costs for larger SMPs are relatively expensive
  • Pace of technology change is increasing
  • Reaching max of current SMP machine requiring a much large server frame and more $$$
  • Too many servers, too expensive, hard to manage

drive towards technology
Drive towards technology
  • Need for a common infrastructure that allows organic / GRID computing
  • Leverage resources for other projects
  • Simpler to create server pools for all applications
  • Need more scalable and available software to glue common hardware together
  • Cannot change existing applications
  • Will not be locked into any particular technology
  • Must reduce management costs and server costs
  • Drive towards LINUX and RAC
  • In only 3 years taken 13.7% of $50.9 B server market

Is Linux ready for companies?
  • DiamlerChrysler uses it in car crash sims. 20% faster 40% cheaper than Unix
  • Morgan Stanley replacing 4K servers running other O/S and saving $100M over 5 years
  • Over 700 eBusiness suite Linux customers
  • Electronic arts found that a 2 proc Intel was equivalent to a 4 proc SMP. 10:1 price diff
  • Cnet got great performance and then sold it’s SMP machines on ebay for more than the Intel ones cost to buy!
  • LINUX is new (10yrs) and volatile but RAC helps

Internal Use of Linux at Oracle
  • Key internal systems migrated to Linux
    • Oracle Files Online
    • Oracle demo systems
    • Oracle outsourcing systems
    • Oracle financial systems
    • More planned

Linux + Oracle + RAC
  • Linux could be considered younger than other more mature operating systems
  • Rapid rate of addition although it’s reaching a level of maturity
  • Better and better enterprise support from vendors
  • Scaling to 4 Procs 2.4 and > 8 with kernel 2.6
  • Oracle RAC provides the mainframe stability and scale out for apps beyond 4 procs
key 9 i rac messages

RAC delivers unprecedented performance and scalability

RAC is the premier high availability database

RAC runs all applications out-of-the-box and unmodified

Bottom line: RAC reduces IT costs. Use all nodes. Nothing wasted

Key 9i RAC Messages

What is RAC?

  • Start small, pay as you grow, unlimited headroom
  • Works with ALL applications
  • Simplified management to rapidly add servers and disk
  • Use with Linux, HP, IBM, Sun, Windows NT

why rac
Why RAC?
  • Benefits of added scalability and added availability when you add extra nodes. Flexible.
  • No need for ANY application changes to run RAC
  • Data is shared amongst all the nodes in the cluster
    • Any application on any node sees all the data
    • When a node crashes no data is lost
  • Workload is partitioned automatically across the available nodes
  • Add and remove nodes flexibility. Runs of all major platforms. Grow with demand. Saves cost

RAC Today

  • Over 200 production reference customers.
  • Across all common hardware platforms.
  • 10i RAC version released
  • Wide delivery of Consulting accelerator services
  • Addition of cluster file systems
  • Certification of common platforms and applications
  • Single most scalable platform for enterprise solutions. Scale on demand and manage effectively.
  • Widely being used by gaming companies now. Electronic Arts, Sony online entertainment and others.

Some RAC References

  • Acxiom – World leader in multi-channel customer data integration
  • Austrian railways- Austrian Railways is the state-owned railroad of Austria
  • British Telecom – World leader in communications
  • Freemarkets– Connecting buyers of goods and services. Moved into production in less than a week!
  • Electronic Arts– Sims online. 20 clusters, 5 nodes, 300K SQL/s
  • Sony Entertainment – Large SMP clusters, scaling and HA
  • SAS – Statistical Analysis Software
  • SITA– State information technology agency
  • UPS – Leader in transportation of goods. 16K tps
  • Vector SCM– Track cars from plant to dealer
