INTRODUCTION
As business operations become more complex, the demand for change in IT increases
accordingly, as do the associated risks that must be mitigated. Today’s IT professionals
are asked to manage more information and deliver it to their users, with ever-increasing
quality of service, in a timely manner. And in today’s economic climate, IT must also
reduce budgets and derive greater value out of existing investments.
Oracle Database 11g Release 2, the latest release of the award-winning Oracle
Database 11g, enables IT professionals to deliver more information with higher quality of
service, make more-efficient use of their budgets, and reduce the risk of change in
datacenters. By deploying Oracle Database 11g Release 2 as their data management
foundation, organizations can utilize the full power of the world’s leading database to
• Reduce server costs by a factor of 5
• Reduce storage requirements by a factor of 10
• Improve mission-critical system performance by a factor of 10
• Increase DBA and developer productivity by a factor of 2
• Maximize availability and eliminate idle redundancy
• Maximize security and enable compliance
• Simplify their overall IT software portfolio
This white paper identifies the key capabilities in Oracle Database 11g Release 2 that
enable IT professionals to deliver more information with a higher quality of service—at a
much lower cost—than has ever been possible before.
Reduce Hardware Costs Through Consolidation
Most datacenters today are a mishmash of hardware and software that have evolved over time to
meet individual business requirements. Datacenters typically consist of a variety of server and
storage silos, plus a complex software portfolio to integrate everything together.
Mixed datacenter environments are very expensive to maintain. A large part of any IT budget—
estimated at as much as 30 percent—is spent on making sure that all these different components
work well with each other, and more importantly, continue to work through the lifecycle of each
component. Maintaining separate server and storage silos is also extremely inefficient. Individual
systems are often over-provisioned with spare processing and storage capacity, which can cause a
great deal of underutilization throughout the datacenter. Managing individual systems to meet
performance, availability, and security expectations is both inefficient and costly.
Unlock the Price and Performance of Commodity Hardware
In the past, organizations have used stand-alone SMP servers as a single shared platform to
consolidate multiple workloads, and Oracle Database 11g Release 2 works very well in this
environment. Oracle Database has 20 years of experience in getting the best SMP performance
and is supported by all major virtualization software, including Oracle VM and logical
partitioning (LPAR) software. Oracle Database 11g Release 2 also offers instance caging, which
enables databases to be confined to specific cores in the SMP environment, removing the need
for virtualization or LPAR software.
However, large SMP servers continue to be very expensive both in initial costs and in the
incremental costs of scaling. Alternatively, small commodity servers running open-source
operating systems such as Linux can be clustered together, offering similar processor and
memory capacity at 4-6x initial cost savings.
Consolidate All Data Processing onto Low-Cost Private Clouds
Oracle Real Application Clusters (Oracle RAC) enables a cluster of low-cost commodity servers
to work together as a single shared database grid or private cloud. Applications can then be
deployed without modification to provide the benefits of consolidation, higher availability, faster
performance, and scalability on demand.
Because you can allocate resources within a private cloud to different server pools, consolidating
multiple applications is easy. For example, a front-office server pool of nodes can be allocated to
run all the databases for CRM systems and Websites. Similarly, a back-office server pool can be
allocated for ERP databases. Nodes can also be allocated to a data warehouse and reporting
server pool. Any unallocated nodes are managed as a free resource server pool.
If, for performance or availability reasons, additional nodes are required for any server pool, they
can be dynamically assigned from the free pool, or re-assigned from another server pool with
lower priority to meet service level requirements in private cloud environments.
Oracle RAC One Node
Consolidation is not only for mission-critical applications. Many IT organizations want to use
this infrastructure to deploy the many departmental and line of business applications in their
management portfolio. Oracle RAC One Node allows organizations to consolidate their many
small to medium-scale databases onto the private cloud. Users get the fault tolerance and
flexibility of Oracle RAC, but databases are run on just a single server.
supports cluster failover, rolling upgrades of hardware and software, and the ability to move a
database between servers in a private cloud.
New grid plug and play features in Oracle Database 11g Release 2 also make it easier to provision
environments, and to add (or remove) additional servers to accommodate greater consolidation
and future business growth.
