Accelerating Database Infrastructure
Using Oracle Real Application Clusters 11gR2 and QLogic FabricCache

 Scalability. QLogic’s FabricCache adapters deploy caching at the HBA within each server in the
RAC cluster. By satisfying many read requests in the server-side cache, FabricCache effectively
offloads the SAN and storage array. This leaves more resources available for processing writes,
which can mean that write performance improves.
Recommendations
Deployment of QLogic FabricCache adapters is conceptually simple. However, to minimize
deployment time and risk, and to maximize the benefits you can realize from Oracle RAC and
QLogic’s FabricCache adapters, we recommend considering the following factors:
Partner with Oracle and QLogic
Oracle and Qlogic, both industry leaders, have been established partners for years. The depth and
maturity of this partnership means that customers can count on joint solutions such as Oracle 11g R2
RAC with QLogic’s FabricCache adapters. By partnering with both companies, customers can increase
value and reduce risk. This leads to smooth, rapid implementation, resulting in a solution that delivers
maximum performance and quality of service for minimal cost.
Start with a thorough assessment of your current database estate
To maximize value of an optimized infrastructure for your database estate, it is important to start with
a thorough assessment of the targeted database community, whether it is a Test/Dev/Qual
environment, production enterprise application implementation, database grid, or some combination
of these. In addition to assessing the Oracle RAC implementation(s) targeted for an optimized
infrastructure, it is also crucial to assess the existing hardware environment.
A thorough assessment will form the basis of an effective implementation plan, as well as assist you in
budgeting and planning the transition to an optimized database infrastructure.
Oracle and QLogic have worked together to establish a knowledge base of methods to completely
appraise your database environment and infrastructure, regardless of size or complexity. Your Oracle
and QLogic representatives will work together to ensure that you receive a complete assessment
package that is appropriate to your needs.
Evaluate the total cost of the solution
Oracle and QLogic will work with you to help you understand the cost and return on investment for
you FabricCache implementation.
Factors affecting cost include:
 Size of implementation
 Type of implementation (production, test/dev, etc.)
 Other implementation projects (consolidation, upgrades,
etc.)
FabricCache adapters:
 No change to Oracle RAC, server
hardware or storage system
 Little or no change to existing
operations
 Simple, rapid deployment
