WHITE PAPER

Introduction

This paper provides performance testing information for two specific

QLogic solutions for Oracle database environments:

• FabricCache Fibre Channel Adapters featuring integrated flash-based

caching for application performance acceleration

• Standard Fibre Channel Adapters featuring high-performance and low-

power requirements for SAN attachment

For FabricCache Adapters, QLogic used Oracle’s Orion workload tool to

test end-to-end server, network, and storage performance operating in an

infrastructure that includes a Fibre Channel attached storage array with

standard hard disk drives as the target and the QLogic FabricCache 10000

Series 8Gb Fibre Channel Adapter as the device under test (DUT). QLogic

chose this configuration to characterize the operational performance of the

FabricCache Adapter in a real-world environment, where an existing legacy

SAN would typically be present. The results provide baseline performance

data for the configured environment without caching enabled, and with

various levels of caching enabled to provide a performance comparison.

Oracle’s Orion workload tool enables architects to effectively develop a

workload that can mimic and stress a storage array in the same manner as

applications designed with an Oracle backend database.

The test’s selected objectives enable the best understanding of application

performance and environmental usage under various user loads with key

indicators such as:

• Transactions Per Second (TPS)

• IOPS

For the testing performed on the standard Fibre Channel Adapters, QLogic

also used Oracle’s Orion workload tool, but used a solid-state storage

system as the target to facilitate a maximum performance environment for

the QLogic and Emulex Fibre Channel Adapters as the DUT.

Server-Side Storage Acceleration

Storage I/O is the primary performance bottleneck for data-intensive

applications such as Oracle. Processor and memory performance have

grown in-step with Moore’s Law—that is, getting faster and smaller—

while storage performance has lagged far behind. Over the past two

decades, delivering performance from data storage has become the bane

of application administrators, and recent challenges are poised to severely

constrain the capabilities of the infrastructure in the face of increasing

virtualization, consolidation, and user loads.

Today’s mission-critical database applications feature Online

Transaction Processing (OLTP) and Online Analytical Processing (OLAP)

workloads that demand the highest levels of performance from servers

and their associated SAN storage infrastructure. The introduction of

multi-processor CPUs coupled with virtualization technologies provide

the resources to meet these demanding requirements within Oracle

database servers, but compound the demand for high-performance,

low-latency, scalable I/O connectivity between servers and

SAN storage.

It is imperative to deploy a high-performance, scalable, server adapter

technology to meet this ever-growing requirement for I/O. The QLogic

FabricCache 10000 Series 8Gb Fibre Channel Adapter, featuring server-

based caching operation, and the QLogic 2500 Series 8Gb Fibre Channel

Adapter, featuring standard Host Bus Adapter operation, provide high-

performance, scalable solutions for database environments.

To help IT decision makers make the best, most informed adapter

choice, QLogic has developed a series of benchmarks showing the

performance and scalability of QLogic FabricCache 10000 Series 8Gb

Fibre Channel Adapters. The benchmarks also show the performance

and scalability advantages of the QLogic 2500 Series 8Gb Fibre Channel

Adapter over the Emulex 8Gb LightPulse

Adapter in a variety of real-

world OLTP and OLAP scenarios using SAN-attached Oracle databases.

QLogic compared the overall performance of the 8Gb adapters when

configured to emulate a real-world SAN with maximum throughput

workloads. These tests highlight the advantage delivered by the QLogic

10000 Series Adapters and the QLogic 2500 Series Adapters in Oracle

environments.
