Success Story: The Susquehanna International Group of Companies



November 20, 2006 12:00 am





SIG is a leading institutional sales, research and market making firm active in financial markets on five continents. The firm offers renowned execution expertise in listed and NASDAQ equities, options, program trading, American Depositary Receipts (ADRs) and is one of the largest liquidity providers in Exchange Traded Funds (ETFs). SIG has more than 1500 employees throughout the world.


SIG’s sophisticated financial trading systems were taxing its aging mid-range environment. With an ever increasing volume of market data, SIG’s back-office servers often came close to redline conditions. The IT staff was also struggling with power and cooling constraints in the data center. SIG needed to revamp its server environment, without sacrificing performance or scalability.

SIG is constantly creating new products and time-to-market is critical in the dynamic financial services market. This called for a refresh of its development environments. SIG needed an operating system platform that would support rapid development and deployment.

Novell Solution

SIG recognized the benefits of moving its UNIX* environment to Linux* would include better performance on AMD-based hardware. SIG evaluated several distributions before selecting SUSE Linux Enterprise Server to run on its servers.

“In the end, Novell’s offerings simply made more financial sense than other distributions, especially when including their respective support models,” said Norbert Thier, Manager of Server Systems at SIG. “Our strategy has been to look for value-based solutions that give us a competitive advantage. When it comes to Linux, SUSE Linux Enterprise Server is the best technology platform for our business.”

SIG runs a variety of mission-critical applications on the SUSE Linux Enterprise Server platform including its databases, several customized trading applications, a large grid computing environment, and Reuters Market Data System (RMDS). With anticipated market data increases of 50-100 percent, SIG now has both the performance and scalability to handle any market spikes for the foreseeable future.


By upgrading its server installation base to SUSE Linux Enterprise Server on x86-based hardware, SIG has increased the performance of its mission-critical systems at least fourfold, without any increase in server costs. The Linux environment simplifies the process of deploying new systems, allowing SIG to keep pace with a rapid growth rate of 30 percent per year.
