Serving more than 365 cities, Banrisul is one of the largest and oldest banks in Brazil. Banco do Estado do Rio Grande do Sul S.A. ("Banrisul" or "Institution") is a publicly traded corporation operating as a multiple-bank entity and works in commercial, credit, financing, and investment portfolios, as well as in mortgage credit, development, leasing, and investment portfolios, including foreign exchange operations, securities brokerage, and management of credit cards and consortia.
With the growing competition, the state-owned institution needed to reassess and revitalize its existing business processes. Banrisul revamped the structure and role of its IT organization. In addition to adopting DevOps practices, the bank’s IT leaders aimed to make greater use of cloud resources, agile methodologies, Internet of Things (IoT) solutions, Artificial Intelligence (AI) technologies, and Machine Learning (ML). To support these ambitions, they made critical updates to the bank's IT infrastructure. With the help of Teletex, a Cisco Gold Partner channel, Banrisul deployed Cisco MDS switches to enhance the performance and flexibility of its Storage Area Network (SAN). With multiple layers of network and storage intelligence, advanced security, and unified management, Cisco MDS switches support scalable and highly available storage networks.
"The Cisco MDS met all our technical requirements and also offered the best price," says Gustavo Barreto, IT Analyst at Banrisul, noting the open bidding process required by law. "It’s easy to configure and easy to use." As a government-managed financial institution serving millions of citizens and businesses in Brazil, Banrisul's services—spanning mobile, online, branches, and partners—must always be available. "It’s not acceptable for us to be offline," Barreto sums up. "The best part of this project was that we did the migration with zero downtime." Teletex set up two independent SAN fabrics, he explains, and migrated them one at a time using automated scripts. In addition to enabling a zero-downtime migration, the two fabrics feature synchronous replication and provide critical redundancy. “The Cisco MDS boosted the performance of our SAN, reduced application latency, and had a direct impact on the customer experience,” says Barreto. “Our services are more accessible, and our transactions are faster,” he adds. Digital transformation journeys take time, and Barreto says the Cisco MDS switches are helping connect Banrisul’s legacy systems with new applications and workloads, 80% of which are virtualized. The switches can support everything from the bank’s old mainframe to a variety of next-generation technologies. With Cisco training and Teletex’s migration scripts, Banrisul plans to increase the use of “infrastructure as code.” “We use migration scripts every day to automate our storage infrastructure,” Barreto says. “We plan to integrate all our containers, virtual machines (VMs), zones, and disks, and will continue to use scripts for configuration, deployment, and orchestration,” he envisions.
