When brought in to help with Linux and SAN performance issues on their multi-tiered systems, Fortuitous provided key performance, design, and tuning expertise to improve performance and transition to higher capacity 64-bit systems.
Fortuitous was able to first tune the existing Linux and SAN systems so that accurate workload baseline data could be collected. Complete tuning recommendations for Linux, DB2, Tomcat, and SAN were provided. After all major Linux and SAN issues were resolved, all tuning goals were successful.
Once baselined and tuned, Fortuitous provided performance models to quantify a design to transition from Linux on 32-bit to 64-bit systems. Key workload and performance requirements were seamlessly mapped onto the new designs. Once implemented, all systems meet or surpass the client's goals.
