Business growth at Banrisul required investments in cutting-edge technological solutions. With a complete portfolio of IBM® high-end solutions such as the IBM DS8880F all-flash storage, IBM Spectrum Storage software, and IBM Z® solutions, Banrisul has reduced costs and rejuvenated its services to customers.

Business challenge

As Banrisul experienced rapid growth, the performance of its storage was impacting key banking systems. Important procedures needed to execute more rapidly in order not to impact the production environment.


With IBM DS8886F all-flash storage, HyperSwap and IBM Spectrum Control, Banrisul has gained significant performance and resiliency for future growth and better customer experience at a lower cost.

Challenges of success

Digital transformation of processes and applications at Banrisul allows the delivery of new experiences and more convenience to its more than 4 million customers in Brazil and abroad. However, as customer transaction levels increase, the back-office transaction workload also grows, placing significant strain on the bank’s IT infrastructure.

Faced with declining systems performance, how could Banrisul continue to deliver outstanding customer service?

To support its operations, Banrisul, which keeps a decades-long partnership with IBM, relies on IBM Z® enterprise servers and IBM Db2® data management software. The data storage subsystem was getting obsolete with usage levels consistently above 70 percent of total capacity. In addition, the data storage subsystem was unable to take advantage of the latest IBM zHyperWrite technology for the IBM Z platform. IBM zHyperWrite is a technology exclusive for IBM storage and allows superior write performance on DB2.

Adding to these challenges, backup and disaster recovery procedures were complex, involving a lengthy set of manual procedures to enable failover. Banrisul invited vendors to submit proposals for new data storage capabilities in an open tender, and, as required by law, looked for the most cost-effective solution.

José Andrade, IT Infrastructure and Operations Manager at Banrisul, remarks, “Not only was there little room for further growth, but poor storage performance was also impacting our IBM Db2 database, which supports a number of critically important business processes. To serve our customers more effectively and continue our successful growth, we wanted sub-millisecond response times, higher throughput, and enough storage capacity for projected business growth until the next Banrisul IT hardware refresh cycle.”

Transformation story
Building a brighter data future

Banrisul uses IBM z14 servers running IBM z/OS 2.2.0 and IBM Db2 database software to support its core banking operations, and designed the storage specifications to support and optimize the processing power and capacity of the z14. The bank issued a public tender for the solution; three vendors made proposals, and, after careful evaluation, IBM’s proposal won the tender.

Banrisul selected IBM DS8886F all-flash storage solutions, designed to deliver extremely low response times, ideal for emerging cloud, mobile, social, analytics and cognitive workloads. Working with IBM Systems Lab Services and Training, Banrisul undertook a comprehensive overhaul of its storage infrastructure, based on new all-flash IBM Storage technology and IBM Spectrum Storage software, which performed according to expectations.

Banrisul selected IBM Transparent Data Migration Facility for z/OS 5.7 to migrate 22TB of data, distributed over 4,270 volumes, without the need to take operational systems offline. Data migration took 15 hours, and existing backup services continued, too, ensuring Banrisul’s data was fully protected even during the transition process.

With the migration to the DS8886F data system complete, Banrisul took advantage of IBM HyperSwap® technology to provide high availability, designed to comply with regulatory demands for business continuity. With HyperSwap, data is mirrored between two fully duplexed storage systems; if one site is no longer available, HyperSwap will automatically failover to the available system, providing continuous access to data.

The bank used this technology with its existing IBM Copy Services Manager software running in a Microsoft Windows operating environment that communicates with the bank’s IBM z/OS partitions to automate and manage replication tasks. Banrisul uses IBM Storage FlashCopy® software to create point-in-time copies that are immediately available for read or write access.

Additionally, Banrisul implemented IBM Spectrum® Control Standard Edition software to support performance and capacity planning and management across all its storage devices, helping the bank to optimize its existing investments and plan for future growth.

IBM Systems Lab Services and Training worked with Banrisul to deploy and configure the IBM DS8886F systems and software to maximize availability, enhance data protection and optimize the IBM z14 and storage environments. Jorge Motter, Mainframe Operations Support Manager at Banrisul, says, “The migration process was smooth, and we completed the deployment with minimal business disruption.”

Combined with excellent services from IBM Systems Lab Services and Training and the IBM Spectrum Storage solutions, IBM DS8886F and IBM z14 offer an outstanding, high-performance and high-resilient solution for Banrisul. José Andrade IT Infrastructure and Operations Manager Banrisul
Results story
Cost-effective and ready for future growth

Mobile and home banking online services rely on the data processed by the IBM z14 server, managed by IBM Db2 and stored on IBM DS8886F. With the integrated IBM solutions in place, Banrisul is seeing significant performance improvements that translate directly into enhanced customer experience.

José Andrade remarks, “The daily process to update checking account transactions that formerly took 19 hours now takes just 13 hours; processing direct debits formerly took 10 hours and now takes 4 hours; and loan payment value updates that formerly took 20 hours now take 6 hours. We did not upgrade the server CPU; these gains are all due to improved data I/O performance from the all-flash DS8886F solution.”

For Banrisul, the introduction of IBM storage technologies has strengthened business resilience and continuity, as José Andrade explains: “The previous system failover process could take up to two hours, with many processes relying on manual intervention. With IBM HyperSwap, failover can be confirmed with a few clicks of a mouse, and we can be back up and running on the second instance in up to 28 seconds.

“In Brazil, banks are required by law to demonstrate that they have the technical capability to failover data processing to a secondary site, and validation is normally completed once or twice a year. With the IBM DS8886F and HyperSwap solution, we can demonstrate compliance immediately and easily with no business downtime, a significant time and cost saving.”

Using IBM Spectrum Control performance monitoring, a capacity planning and storage management software, Banrisul captures and monitors more than 200 metrics across its storage landscape. This helps the organization improve the management of these critical IT resources without increasing headcount in its technical team.

While Banrisul’s primary objective was to enhance customer service by solving technical challenges, the bank has also reduced its total cost of ownership through lower energy consumption and reduced server room real estate. The all-flash DS8886F is around half the weight and size of a disk-based array, and consumes about half the energy—and, consequently reduces the data center air conditioning load, lessening the IT environmental impact.

José Andrade concludes, “The performance and lower total cost of ownership of the IBM DS8886F will directly contribute to enhancing the customer experience and supporting Banrisul’s ongoing business success. Combined with excellent services from IBM Systems Lab Services and Training and the IBM Spectrum Storage solutions, IBM DS8886F and IBM z14 offer an outstanding, high-performance and resilient solution for Banrisul.”
