Consolidating Oracle Databases on the Dell PowerEdge R820 Server Using Oracle VM
5
Executive summary
The Dell™ enterprise portfolio is evolving to incorporate better-performing, more energy-efficient, and
more highly-available products. With the introduction of Dell’s 12th generation server product line,
customers have an opportunity to improve their total cost of ownership by consolidating distributed
legacy environments.
With the advent of virtualization technology, datacenter resources can be better utilized.
Virtualization enables you to create multiple virtual servers within a single physical server. The latest
Dell PowerEdge 12
th generation servers are equipped with greater CPU, memory, and network
resources. Coupling virtualization with the latest and powerful Dell PowerEdge 12 th generation 12G
servers delivers benefits far beyond simple physical server consolidation: using Oracle VM
virtualization, multiple databases can now be consolidated into a single R820.
Dell strives to simplify IT infrastructure by consolidating legacy production environments to reduce
data center complexity while still meeting customers’ needs. The tools and procedures described in
this whitepaper can help administrators test, compare, validate, and implement the latest hardware
and database solution bundles.
This whitepaper explains how to:
 Consolidate multiple legacy servers to PowerEdge R820 Servers.
 Consolidate and run multiple oracle databases on a single PowerEdge R820 server using Oracle
VM virtualization.
 Optimize the TCO of Dell solutions.
 Achieve the benefits of consolidation and virtualization.
Key findings include:
 10:1 to 12:1 consolidation possibility
 50% Power Consumption Savings
Introduction
Server consolidation can be defined as maximizing the efficiency of server resources, thereby
minimizing the infrastructure, associated power and cooling, rack footprint, and licensing costs.
Consolidation essentially solves a fundamental problem—often referred to as server sprawl—in which
multiple, underutilized servers take up more space and consume more power resources than the
workload requirement indicates.
Server consolidation can be done in both physical and virtual infrastructures. This whitepaper discusses
the use of virtual consolidation using Oracle VM virtualization. Consolidation in a virtual environment
offers more flexibility to the customer.
 Resources can be used more flexible manner—add CPU, memory and network resources as and
when needed based on requirements
