Client Profile & Background
A leading commercial bank in Jakarta with over 500 branches nationwide, processing an average of 2 million daily transactions. The bank's IT infrastructure supports core banking applications, mobile banking platforms, and ATM networks, serving both retail and corporate customers. The existing server environment consisted of a mix of legacy HP ProLiant DL380 Gen9 and Dell PowerEdge R730 servers, running on VMware vSphere 6.5. Storage was provided by a mix of SAN and NAS devices, including older Synology RS3617xs units. The bank had recently expanded its digital services, resulting in a 40% increase in data volume and transaction throughput, straining the aging infrastructure.
The IT team consisted of 15 engineers managing on-premises data centers and a private cloud. The bank's compliance requirements mandated adherence to OJK regulations, including data localization, disaster recovery testing every six months, and encryption of data at rest and in transit. The bank's leadership recognized the need for a server refresh to improve performance, enhance security, and reduce operational costs.
02
Technical Challenge
The bank faced several critical technical challenges. First, the legacy servers were experiencing performance bottlenecks during peak hours, with CPU utilization consistently exceeding 85% and memory usage at 90%. This led to transaction processing delays of up to 500 milliseconds, impacting customer experience. Second, the existing backup infrastructure using Veeam Backup & Replication v9.5 was failing to meet the recovery point objective (RPO) of 15 minutes; actual RPO was averaging 4 hours due to slow backup windows and insufficient storage capacity. The backup window had extended to 12 hours, causing backup failures for critical databases. Third, the storage arrays were nearing end-of-life, with one Synology unit experiencing a controller failure that took 8 hours to recover, exposing the bank to data loss risks. Fourth, the bank's disaster recovery site in Bandung was not fully synchronized, with replication lag exceeding 24 hours for some systems. Finally, the bank needed to achieve ISO 27001 certification, requiring enhanced security controls and audit trails.
The bank's IT director estimated that a server failure during peak hours could cost up to IDR 5 billion per hour in lost transactions and penalties. The challenge was to procure and deploy a new server infrastructure that could handle 3x the current workload, reduce RPO to under 1 hour, and ensure 99.999% availability, all within a budget of IDR 15 billion.
03
Implemented Solution
Intilogy designed a comprehensive server procurement and implementation plan centered around server and storage modernization. The solution included deploying 20 units of HP ProLiant DL380 Gen11 servers with Intel Xeon Platinum processors and 512GB RAM each, configured in a VMware vSphere 8 cluster for high availability. For storage, we implemented a combination of Synology SA6400 all-flash arrays for primary workloads and QNAP TS-h1290FX for near-line storage, connected via 25GbE networking. The backup infrastructure was overhauled with Veeam Backup & Replication v12, leveraging immutable backups and direct-to-object storage to Amazon S3 for offsite copies. We also implemented hyperconverged infrastructure using Nutanix for specific workloads to simplify management. The disaster recovery site was upgraded with identical hardware and real-time replication using VMware Site Recovery Manager, achieving a recovery time objective (RTO) of under 15 minutes. All servers were integrated with cybersecurity solutions, including endpoint detection and response (EDR) and network segmentation via Fortinet firewalls.
The implementation was phased over 6 months to minimize disruption. Phase 1 involved migrating non-critical workloads to new servers, Phase 2 migrated core banking applications, and Phase 3 established the disaster recovery site. The bank's IT team received training on managing the new infrastructure, including Veeam backup procedures and Synology storage management.
04
Results & ROI
The server procurement project delivered significant measurable results. Transaction processing latency dropped from 500ms to under 50ms, improving customer satisfaction. The backup RPO was reduced from 4 hours to 15 minutes, and the backup window shrank from 12 hours to 2 hours, eliminating backup failures. The RTO for disaster recovery improved from 24 hours to under 15 minutes, ensuring business continuity. The bank achieved 99.999% uptime for its core systems over the first year, avoiding any significant outages. Operational costs were reduced by 30% through server consolidation and energy efficiency of the new hardware. The bank successfully obtained ISO 27001 certification within 12 months, enhancing its reputation. Financially, the bank estimated a return on investment (ROI) of 250% over three years, considering avoided downtime costs and improved operational efficiency.
The new infrastructure also enabled the bank to launch new digital services, such as a mobile loan application, which increased revenue by 15% in the first year. The IT team reported a 50% reduction in time spent on maintenance and troubleshooting, allowing them to focus on innovation. The bank's leadership commended the project's success, and Intilogy was engaged for ongoing managed services and infrastructure optimization.
