Iowa Network Services began offering Internet services starting in 1993, and is one of the largest independent Internet Service Providers (ISPs) in Iowa, supporting nearly 80,000 subscribers, hosting more than 1,000 web sites and providing services for 150 telecommunications companies across the state.
With Oracle Solaris, Iowa Network Services has substantially improved the availability and reliability of their services, achieving close to 99.999% uptime.
Using the built-in virtualization capabilities of Oracle Solaris Containers, Iowa Network Services initially ran 130 virtual servers housed on 36 physical servers, reducing hardware management needs, equipment costs and space requirements, increasing the flexibility of server resources and providing a 25% performance improvement from consolidation of services.
Consolidating the number of physical servers enabled Iowa Network Services to also reduce support costs, decrease power and cooling requirements and improve personnel efficiency, resulting in a 15% reduction in operational costs.
Iowa Network Services is also using Oracle Solaris Containers to establish isolation mechanisms that help improve resource use and provide all workloads with access to the appropriate amount of computing resources.
The Oracle Solaris Legacy Containers capability allows Iowa Network Services to run their Solaris 8 and 9 Oracle Solaris applications within multiple Oracle Solaris environments on a single system, immediately gaining scalability and performance benefits, without modifying existing applications.
Iowa Network Services has consolidated 36 servers onto four SPARC T-series servers, reducing its footprint by more than 85 percent.
Iowa Network Services is also evaluating Oracle Solaris 11 Express and expects to migrate to Oracle Solaris 11 in the future.
"Oracle Solaris on SPARC servers is a key component of our infrastructure. With Oracle Solaris Containers, we can create multiple private execution environments within a single instance of Oracle Solaris. With each environment having its own identity, it behaves as if it's running on its own system, making consolidation both easy and secure", stated Steve Guntly, Manager, Systems Administration, Iowa Network Services Inc. "We are looking forward to testing Oracle Solaris 11 technologies and features on the SPARC T3-1 server and leveraging the improved software and hardware integration and expanded virtualization capabilities, with hopefully even better performance and reliability."
