Case Study

Founded in 1928, Banco do Estado do Rio Grande do Sul S.A. (Banrisul) is a state-owned bank operating mainly in Rio Grande do Sul, Brazil. One of Brazil’s largest and most profitable banks, Banrisul employs more than 10,000 people and reports annual revenues of approximately $3.1 billion.

Banrisul has experienced impressive growth in recent years: in the first half of 2011 the bank recorded a 43.8 percent increase in net income on the previous year. Banrisul aims to build on this success to consolidate and maintain its leadership position in the region. Technology represents a core focus of this strategy, and the bank is constantly seeking to optimize its computing infrastructure.

Keeping pace with strong growth
As Banrisul expanded its operations, scalability became an increasing challenge for its Intel processor-based servers. These servers were running Red Hat Enterprise Linux and supporting Oracle databases for internet banking and financial systems. The company was concerned with the lack of flexibility of this configuration, which was impacting its ability to support increasing numbers of clients and transactions, and increasing the time-to-market for new products and services.

Ronaldo Rapacki, IT Development Manager at Banrisul, explains: “If we wanted to provision new systems or add more capacity, this meant a complicated and slow process of procuring and then provisioning new physical machines from scratch.”

Migrating to IBM System z
Banrisul decided to take advantage of Integrated Facility for Linux (IFL) engines on its existing IBM System z servers to run its Oracle databases in a virtualized environment. This would allow it to considerably reduce the time, effort and expense associated with expanding its hardware infrastructure.

“We have been running Linux on System z for a number of years now, and have activated several IFLs,” remarks Rapacki. “Adding more capacity was easy: we just activated more pre-owned IFL processors. Activating each additional IFL has proven to be very simple and given Banrisul more capacity to host new workloads.”

Following a successful proof-of-concept run by IBM, Banrisul moved ahead with a full-scale migration of its Oracle databases to existing IBM System z10 Enterprise Class (z10 EC) servers in late 2011. Banrisul began by migrating its most critical credit database, and then worked to consolidate the majority of its remaining databases to the System z platform.

Banrisul later upgraded its IBM z10 EC servers to IBM zEnterprise 196 (z196) servers, providing considerable performance improvements across a number of workloads. For example, batch processing time for Banrisul’s credit database has been reduced from ten to six hours, a 40 percent saving.

Boosting resource utilization and efficiency
The virtualized Linux environment on the IBM z196—enabled by IBM z/VM®—offers high levels of processor utilization, so that a single IFL is able to handle workloads equivalent to a large number of x86-based servers. The IBM zEnterprise consumes much less energy than the company’s old Intel-based servers, allowing Banrisul to improve its control of energy usage in the data center.

System management has been simplified, thanks to advanced IBM z/VM virtualization and the IBM zEnterprise Unified Resource Manager, which provides IT administration with a unified view for managing practically the entire Linux on System z computing environment.

The IT team can easily and dynamically adjust the allocation of processors and memory without disruption to the running applications, which helps to ensure optimal resource utilization and the most efficient delivery of database services to end users and applications.

Rapacki concludes: “We have been able to cut the number of CPUs required to support our credit database by more than 50 percent, and we are still seeing the same level of performance.”.
