Introduction
HP Open Source Middleware Stacks (OSMS) offer building block applications, such as the Web
Server; technical blueprints, and documents such as this Tomcat Sizing Guide which describes
the maximum workload that HP ProLiant c-Class Blade Servers are capable of supporting; and
consulting services to speed the successful implementation of an open source strategy.
Executive Summary
The HP Open Source Integrated Portfolio (HP OSIP) comprises a range of products and services
designed to verify that customers can successfully realize the cost and feature benefits of adopting
open source software in their IT environments. HP Open Source foundation components include
the base components of an open source-based ecosystem. HP servers and storage are validated
to run the Linux operating system together with the supported commercial Linux distribution.
The results published in this document were achieved using the Apache benchmarking tool and
Apche JMeter for each of the HP ProLiant c-Class Blade Servers. Various test configurations and
test environments were used and documented to provide readers an opportunity to understand
the testing methodology.
Intended Audience
The intended audience for this document is anyone who is interested in determining the Tomcat
user connection workload that can be supported on a given HP ProLiant c-Class Blade Server
and details for deploying a hardware environment based on the Tomcat environment requirements
of certain applications.
Scope and Purpose
This document presents the results of a series of benchmark tests performed using the Apache
Benchmarking tool and Apache JMeter. The tests were conducted running a Tomcat application
server to evaluate system performance when running a web application under a heavy load. The
following HP ProLiant servers were used in this test: BL460c, BL480c, and BL465c. The benchmark
data provided in this sizing guide can assist customers in determining which HP Proliant c-Class
Blade Server meets their Tomcat server requirements along with how-to information for
configuring the HP Proliant c-Class Blade Server and storage in a specific production environment.
HP provides quality assurance from extensive integration testing with open source software and
HP hardware so that you can confidently deploy the complete stack. Once you have completed
a successful evaluation, you have the flexibility to “do it yourself” or get assistance from HP to
incorporate open source stacks into your existing IT infrastructure.
