The 4Gb HBA of Choice
In Oracle Environments
QLogic vs. Emulex 4Gb Fibre Channel HBA
Performance Benchmarking with Oracle
Workloads
Executive Summary
Today's mission-critical Online Transaction Processing (OLTP), Online Analytical Processing
(OLAP) and Web applications demand the highest levels of performance from their database
servers and storage infrastructure. To satisfy this demand, organizations are making the transition
to 4Gb Fibre Channel SANs, and IT decision makers are under pressure to select the right
components in order to ensure a cost-effective and scalable solution.
A critical element of overall SAN performance is the selection and deployment of a Host Bus
Adapter (HBA) with the right architecture. With the introduction of multi-processor CPUs coupled
with virtualization technologies, high performance database solutions need to be complemented
with high performance and scalable IO connectivity. A wrong choice can result in management
complexity and limit an organization's overall business agility to meet continually evolving business
needs.
To help IT decision makers make the best, most informed HBA choice, QLogic has performed a
series of head-to-head performance benchmarks showing the I/O performance and scalability
advantages of the QLogic SANblade™ Pro 2400 series HBAs over Emulex® LightPulse® HBAs in
a variety of real-world OLTP, OLAP and Web scenarios using SAN-attached Oracle databases.
QLogic compared the overall performance of the 4Gb HBAs when attached to industry leading
storage arrays and solid state drives to emulate a real-world SAN with maximum throughput
workloads. Our tests highlight the advantage delivered by QLogic's SAN Pro architecture in
Oracle environments.
Key Findings
For demanding enterprise database applications, choosing QLogic 4Gb FC HBAs provides:
•
33% Higher Performance
•
Using best-in-class Oracle™ and EMC™ components in OLTP, Web and
OLAP workloads indicative of real-world storage configurations, QLogic HBAs
demonstrated 33% better throughput than Emulex HBAs.
•
28% Superior Scalability
•
In high-performance database applications, emulated with Oracle workloads,
QLogic's SANblade 2400 series dual port HBAs deliver 28% higher IOPs
compared to the Emulex's 11000 series HBAs.

  • Page 2 QLogic vs. Emulex HBA Performance Benchmarking with Oracle Workloads Introduction The objective of this exercise was to test and compare the I/O performance of QLogic and Emulex 4Gb Fibre Channel HBAs in a representative selection of database-driven workloads, a configuration arrived at through a combination of customer requests as well as common reference within Oracle user groups.
  • Page 3 Test Procedure The test procedure using an enterprise storage array was as follows: 1. A QLogic 4Gb PCI Express to Fibre Channel HBA (QLE2460) was installed on the test server using the appropriate STORport miniport driver. 2. Eight LUNs of 60 GB each were created on the enterprise storage array and mapped to the first port.
  • Page 4 (LPe11000). Test Results Performance of the QLogic and Emulex HBAs was measured based on a critical parameter - the rate at which the data is parsed by the HBAs (megabytes per second, or MBps). Higher MBps values denote greater throughput and a higher level of performance.
  • Page 5 Dual Port Scalability with Oracle Workloads Test Setup The test setup consisted of the latest 4Gb HBAs from QLogic and Emulex, running on current commercially available drivers, housed in a Dell® PowerEdge™ 6850 server running Windows® Server™ 2003 operating system. The Dell server was connected to a RamSan-400 with 32 GB total capacity through a QLogic®...
  • Page 6 Fibre Channel HBA (LPe11002). Test Results To test the scalability of QLogic and Emulex HBAs, a set of OLTP tests were run using the RamSan configuration as described above, using dual port HBAs. OLTP is the most common workload in the enterprise giving a good indication of the HBA’s scalability in a production setting.

  • Page 7: Summary And Conclusion

    28% higher IOPs compared to Emulex HBAs. The key to the increased performance advantage can be attributed to the SAN Pro architecture that is designed into QLogic 4Gb FC ASICs and HBAs. Some of the key Performance Foundations of the SAN Pro architecture include:...
  • Page 8 Lower the hardware total cost of ownership (TCO) especially with emerging, high-performance database applications that will be used in conjunction with emerging server virtualization technologies and high-performance Grid-computing. QLogic HBAs provide higher IOPs and throughput to account for high bandwidth requirements to meet the needs of enterprise SANs. •...
