Mandip BhullerFastest ROI: Linux RAC clusters

Oracle Corporation

“I'm doing a (free) operating system (just a hobby, won't be big

and professional like gnu) for 386(486) AT clones ….”

Linus Torvalds Usenet posting, 1991

“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

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

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

Oracle’s Commitment toLinux: Products

Every Oracle Product Runs on Linux Today

Oracle in the Linux Community

Integrated Development and Support– Oracle, Red Hat and United Linux development

teams integrated in a non-exclusive partnership– Oracle contributes to Linux kernel code

Quality Assurance– Oracle QA now part of Red Hat and United Linux

development process

Open-source Contributions

Established Linux kernel team making contributions to open-source under GPL

– Oracle Cluster File System

Worked with Red Hat, SuSE and the open source community to drive features into Linux

– Improved I/O throughput– Improved memory utilization– Improved SMP scalability– Graceful degradation under load

Oracle’s Commitment toLinux: Customer Support

Direct support of Linux worldwide– Red Hat Enterprise Linux AS and ES– UnitedLinux

Single point of contact for support Single point of solution for support No additional Oracle support contract required

Oracle’s Commitment toLinux: Security

Submitted for EAL2Defining the path for EAL4

“We run our whole business on Linux.”“We run our whole

business on Linux.”

Linux: Oracle’s Choice

Internal Use of Linux at Oracle

Key internal systems migrated to Linux– Oracle.com– 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 9i 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

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

Cache Fusion: Superior Performance of a SHARED CACHE

Only cluster database that scales out-of-the-box

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.
