"IBM provided our bank with the guidance and system improvements we needed to improve our performance, mitigate enterprise risk and continue the superior service delivery for which we are known." - Chief information officer, a full-service Swedish bank
A full-service Swedish bank
Founded in the late 1800s, this Swedish financial institution has evolved into a full-service bank with network branches in Sweden as well as Denmark, Finland, Norway and Great Britain. In the early 1970s, the bank decentralized the management of its organization to allow decisions to be based on local customers’ requirements. As a result, the bank realized remarkable success.
Service delivery advances prompted a Swedish bank to reevaluate its enterprise risk management capabilities.
IBM Resiliency Consulting Services transformed the bank’s mainframe systems using IBM® GDPS® and IBM HyperSwap® technology to help reduce operations risk.
Enhanced business continuity and resiliency capabilities optimize recovery point and recovery time objectives for superior customer support.
Founded in the late 1800s, this Swedish financial institution has evolved into a full-service bank with network branches in Sweden as well as Denmark, Finland, Norway and Great Britain. In the early 1970s, the bank decentralized the management of its organization to allow decisions to be based on local customers’ requirements. As a result, the bank realized remarkable success. It has more satisfied customers than peer banks, is one of the most cost-effective listed full-service banks in Europe, and every year during the past 40 years has had higher return on equity than the average of peer banks.
The full-service Swedish bank’s IT environment consists of two data centers located 5 km apart. In 1998, it was the first bank to implement a business continuity strategy based on IBM Geographically Dispersed Parallel Sysplex™ (GDPS), Peer-to-Peer Remote Copy (PPRC) and metro mirror technologies to support its mission-critical banking applications in its test and production IBM System z® mainframe environments. Added system demands prompted by new business growth and Internet and mobile banking technologies intensified the bank’s need for continuous availability for its IBM-based IT infrastructure. The financial institution’s zeal to maintain its flexible, streamlined operations model prompted it to return to IBM Global Technology Services® to optimize its infrastructure and enterprise risk management capabilities.
The IBM Resiliency Consulting Services team reviewed the bank’s existing infrastructure and then developed a strategy to strengthen and streamline its mainframe environment and business continuity processes. The IBM team upgraded the bank’s dual-site IT infrastructure with two IBM System z10® Enterprise Class (z10 EC) servers running the IBM z/OS® V1.11 operating system and IBM z/VM® V5.3 virtualization technology. The virtualization capability was particularly important because it provides the flexibility to increase capacity as dictated by business needs. The two System z10 EC servers are set up in a GDPS configuration to help ensure that business applications are kept up and running. The infrastructure uses IBM HyperSwap technology, a function that enhances the ability to provide uninterrupted operations by switching from primary to secondary disk subsystems in near-real time. The HyperSwap solution helps minimize potential disk failures while optimizing enterprise risk management and enhancing business resiliency. For additional protection, IBM Tivoli® System Automation Manager software was integrated to provide seamless automation of both system and network resources, which helps minimize complexity, maximize availability and optimize operations. Though the IBM solution meets the company’s main objective of continuous system availability and disaster recovery, to further strengthen its infrastructure, the client relies on IBM Technical Support Services to maintain its IT environment.
