Case Study: Raiffeisen Bank Serbia cuts data warehouse costs by 65% and accelerates data analysis with Hitachi Vantara

Raiffeisenbank Cuts Data Warehouse Costs by 2/3 and Accelerates Data Analysis With Hitachi Unified Compute Platform for Oracle Database

Raiffeisen Bank Serbia was struggling with an aging, underperforming single data warehouse that could not keep pace with growing data volumes, provide fast analyses for business decisions, or meet stricter regulatory reporting requirements. Daily loads took about 20 hours and data was often available only two days later, prompting the bank to seek a faster, lower‑cost platform; they selected Hitachi Vantara’s Hitachi Unified Compute Platform for Oracle Database.

Hitachi Vantara deployed a UCP 6000–based x86/RHEL solution and migrated the warehouse with minimal disruption, cutting daily load time from 20 to 10 hours and tripling user query performance. The new Hitachi Vantara platform reduced total cost of ownership by 65%, lowered annual CO2 emissions by 270 tons, added near‑instant flashback recovery and real‑time mirroring, and delivered faster development and improved compliance and decision‑making.
