Case Study: Seven Bank achieves nonstop, scalable 24/7 ATM transaction switching with Hewlett Packard Enterprise (HPE) Integrity NonStop BladeSystem NB54000c

Seven Bank banks on HPE Integrity NonStop to handle Critical Transaction Switching

Seven Bank, a Japanese financial institution operating 22,000 ATMs and handling as many as 5.7 million transactions per day, needed a highly available, scalable relay platform to ensure continuous ATM and online banking services. The bank’s legacy servers could not meet projected growth or nonstop requirements, so Seven Bank turned to Hewlett Packard Enterprise and its HPE Integrity NonStop BladeSystem NB54000c (with an HPE Integrity NonStop NS2200 for development) to support mission‑critical transaction switching.

Hewlett Packard Enterprise, working with partner NRI, deployed four HPE Integrity NonStop BladeSystem NB54000c servers in an active‑active East/West configuration running Intelligent Wave’s NET+1, delivering nonstop 24/7/365 relay of ATM transactions with no data loss. The HPE solution provided the performance and incremental scalability to meet ten‑year growth projections, handled spikes in workload, ensured PCI compliance for growing foreign‑card use, and enabled Seven Bank to reliably process 5.7 million transactions per day across its nationwide ATM network.
