Joint-Stock Bank: Exadata X9M to X10M Upgrade, Expansion & Data Migration
Background
A joint-stock bank ran its core transaction database on Oracle Exadata X9M. Compute resources were tightening as business volumes grew, and the Intel Optane PMEM layer that X9M depends on has been discontinued, creating uncertainty for future expansion and parts support.
Solution
Leveraging the X10M platform (AMD EPYC processors, 192 cores per database server, DDR5 memory, 100 Gb/s RoCE internal fabric, and lower typical power for equivalent capability), we designed an "expand then migrate" approach: two new X10M database servers joined the existing RoCE fabric alongside X9M storage cells, RAC instances were migrated in batches, and cutover was performed rolling.
Scope of Service
- Supply, rack installation and elastic-configuration integration of X10M database servers
- Phased RAC instance migration with rolling cutover
- Performance benchmarking and SQL tuning before and after migration
- Three-year maintenance: 7x24 emergency response and advance parts replacement
Results
All instances were migrated within the cutover window with no business impact. Cores per database server increased 3x versus X9M, peak-hour utilization of the core transaction database dropped noticeably, and the original X9M servers were repurposed as a test environment to protect the existing investment.
