City of Chicago

redhat.com | Red Hat Solutions: "One of the most well known cities in the United States, Chicago prides itself on finding a better way to do things�from strengthening public education to inventing Cracker Jacks, lowering crime to building the first skyscraper. The city's infrastructure has historically been a multi-platform environment that included about 100 Solaris servers used to run a large number of Oracle Databases and applications.

BIS had three primary goals when they began to consider Linux:

* Reduce the server hardware, maintenance and operating costs
* Prove that Linux could effectively run enterprise-level applications
* Increase flexibility in choosing hardware vendors for significant potential cost savings

Realizing the potential for open source technology to reduce the cost of hardware and IT operating costs, BIS partnered with HP, Red Hat and Systems Solutions Inc. (SSI) to kick off a Red Hat Enterprise Linux pilot project. SSI's systems engineers installed the HP DL580 G2 Server with Red Hat Enterprise Linux AS v.2.1, Oracle 9i Database, and HP MSL Tape Library with backup software from Legato.

Sun Solaris benchmarked at 50,268 transactions per minute, while the HPDL580 G2 with Red Hat Enterprise Linux benchmarked at over 149,500 transactions per minute"
