In the past, EnBW had been running its 350 SAP instances on Solaris servers. The company wanted to investigate whether it could achieve greater functionality, reliability and performance at lower cost, and decided to re-evaluate its IT strategy.
Thomas Schlindwein, Professional Systems Engineer at EnBW, said, “SUSE Linux Enterprise Server is SAP’s own preferred platform for application development, and we realized that migrating to the SUSE operating system would offer us fast access to the most advanced SAP application functionalities, which may only be released later for other platforms.
“Next, we began looking for a rock-solid platform for our mission-critical SAP systems, and decided to replace our existing SPARC infrastructure with state-of-the-art Fujitsu servers.”
Working with Fujitsu, EnBW deployed six Fujitsu PRIMERGY RX600 S6 servers plus ten Fujitsu PRIMERGY RX300 S7 servers featuring Intel processors. Most of the company’s business-critical systems run on SUSE Linux Enterprise Server, while its productivity software runs on Microsoft Windows. To meet demands for data storage, EnBW also deployed high-performance NetApp devices.
EnBW uses VMware vSphere 5 technology on the Fujitsu servers to run more than 900 virtual instances.
“We asked our partner, B1 Systems, to help us find a tool for central system and configuration management,” said Thomas Schlindwein. “On the B1 Systems team’s recommendation and with support from SUSE, we decided to deploy SUSE Manager software to help our IT team manage the huge number of servers efficiently.”
SUSE Manager provides management, provisioning and monitoring capabilities for SUSE Linux Enterprise Server systems. Using the software enabled EnBW to automate much of the work involved in the migration, saving time and reducing the risk of human error. Once the migration was complete, EnBW began using the tool to automate other tasks such as patch and package management, in order to accelerate its IT administration processes.
The new platform is extremely reliable, meaning that EnBW is experiencing less unplanned downtime for the systems.
Deploying the SUSE solution with SUSE Manager has also streamlined IT management processes at EnBW, enabling personnel to focus on higher-value development initiatives. In the future, the solution will scale to meet the needs of EnBW’s growing business.
“We were impressed by the offering from SUSE and Fujitsu, who worked quickly to deliver an advanced solution that meets our business needs,” said Thomas Schlindwein. “The new solution delivers a real value add for our business, and we were extremely impressed by the competent service we received from SUSE, Fujitsu and B1 Systems.”
