Due to the increasing demands on the chain’s central IT, a consolidation of the existing server environment became necessary. In order to achieve this, the virtualization software Xen was installed on redundant high-performance servers. Thus, 20 virtual machines are able to perform many different services for more than 1000 users, ranging from the central Web-Server station to the handling of documents.
In the course of this reorganization it became necessary to keep the storage – to which all these virtual machines are to have access – redundant and highly available. At the same time the performance is to be such, that every individual service is available at its full capacity.
Here, the storage manufacturer EUROstor was commissioned to offer and to install a solution.
