ATM Network Upgrade Helps SunTrust Keep Up With Growing Volumes

By upgrading servers and moving ATM transaction traffic to an existing TCP/IP network, the bank says it has simplified and increased throughput for its ATM network.

SunTrust Bank has gone live with ACI Communication Services for Advanced Networking to enable its ATM network to keep up with growing transaction volumes.

SunTrust has been an ACI BASE24 customer for 25 years, running on HP NonStop servers and interfacing to IBM System z host applications. The bank wanted to simplify network configuration by eliminating the separate SNI (SNA Network Interconnection) network; bring ATM transaction traffic into its primary TCP/IP network; and improve network throughput, availability and reliability while avoiding costly impacts to host applications.

In conjunction with a server upgrade from HP NonStop K-Series to HP Integrity servers, the bank deployed ACI Communication Services for Advanced Networking - HPR/IP (High Performance Routing/IP) to achieve these goals.

"The consolidation of servers and increased transaction volumes within the enterprise required highly available, extremely fast connectivity," said James Bone, vice president of EDS ATM Development at SunTrust, in a statement. "With ACI's HPR/IP solution and IBM's System z Enterprise Extender we exceeded throughput requirements while reducing both response time and demand on system resources. In addition, with ACI's HPR/IP solution, we eliminated the IBM 3745 Communications Controller with no application code changes."
