The Hartmann Group consolidates global SAP applications to just two IBM Power 750 servers


Published on

With the help of IBM, the Hartmann Group migrated to the latest releases of SAP ERP applications, and consolidated multiple servers to IBMPower servers featuring IBM POWER7 processor technology. Using IBM virtualization technologies embedded in the POWER7 architecture and exploited by IBM AIX, the Hartmann Group has created a high-performance, flexible infrastructure solution capable of handling increased workload, meeting business service level agreements and reducing operational costs.For more information on Storage System, visit http://ibm.co/LIg7gk.
