About the Project
itelligence and Randstad began their first joint project: In the company’s data center in Bautzen (Germany), itelligence was able to set up a system landscape with the highest availability for around 3800 SAP ERP work stations, 3800 Business Warehouse, 3800 Portal and 3000 Customer Relationship users – in just four and a half months. Support for technical implementation was provided by becom Informationssysteme GmbH, a full-service provider for SAP from Bielefeld.
The conception, supply and installation of the technical hardware infrastructure was attended to by becom. Ultimately, it was deemed necessary to operate the SAP system landscape in the future assisted by several linked and highly available IBM pSeries servers running on IBM AIX. The system landscape is supplemented by a highly available and dynamically scalable IBM storage area network (SAN).
The move of the eight SAP production systems posed additional challenges: only one long weekend was available to take over all systems. As part of the taking over, the SAP systems were largely consolidated under AIX; a cross-platform migration of the database was also performed for all systems. Altogether, along with the ERP solution, the itelligence data center in Bautzen now also operates BI, CRM, Portal, XI, E-Recruitment, Solution Manager, Escriba printing and forms preparation as well as Unispool for print management.
Other additional Randstad systems are hosted in the itelligence data center – for example, the Citrix Server farms, Lotus Notes e-mail system, the IBM CommonStore archive system with 10 TB memory, the firewall systems and much more. As a result of the move Randstad now enjoys system availability of 99.72% – and with this a guaranteed maximum downtime of two hours and 24 x 7 around the clock support.
