Deutsche Postbank has doubled its IT infrastructure to deal with its SAP software, and is planning to process transactions for two German banks.
Postbank's SAP system, set up in October 2003 and running on IBM hardware, processes more than 10 million transactions a day, and could easily handle double that figure, said Postbank's press officer Hartmut Schlegel.
The SAP system is designed to manage customer transactions from Postbank's online and IVR (interactive voice responsive) services, plus its 9,000 branch offices.
The SAP software will allow Postbank to offer processing services to other banks, such as Deutsche Bank and Dresdner Bank, who will outsource their payment transactions to Postbank later this year.
SAP was brought in to replace a legacy system, running on Fujitsu-Siemens Computers equipment, which was barely keeping up with the demands put upon it, Schlegel said.
The system handles transactions and stores details of individual checking accounts. Later this year, modules for savings accounts and loan accounts will be added, and the system is capable of creating and handling new products, such as checking accounts with loan facilities included.
Postbank has centralised all IT hardware at a datacentre in Bonn. The IT hardware was previously spread across six centres around Germany, and the centralisation has reduced costs.
The IBM equipment installed includes four IBM z900 mainframes to be used as SAP database servers with DB2/zOS as the database for SAP account management.
Eight IBM eServer p690 systems with Power4 processor technology and up to 32 processors each have been installed as SAP application servers, and four ESS 800 disc systems have been installed, providing a total storage capacity of more than 40Tbytes.
Data is mirrored to a remote datacentre via PPRC (peer-to-peer remote copy) to provide security.
