Overview

A leading European financial institution partnered with HCLTech to modernise its data centre infrastructure and establish a future-ready platform capable of supporting core banking operations while enabling long-term digital transformation. The organisation operated a large estate of ageing servers that supported transaction processing, middleware services, reporting platforms, developer environments and analytics workloads.

As infrastructure demand continued to grow, the client faced increasing operational complexity, rising power consumption and higher maintenance costs. At the same time, the organisation required greater compute capacity to support business growth while maintaining the performance, availability and security standards expected of a regulated financial institution.

HCLTech designed and implemented a large-scale infrastructure transformation built on the latest-generation Intel Xeon processor platform. The solution consolidated hundreds of legacy servers into a modernised compute environment that delivers higher performance, improved efficiency, lower operational costs and readiness for emerging AI-driven workloads. The result is a streamlined infrastructure foundation capable of supporting critical banking services today while providing the flexibility required for future innovation.

The Challenges

The client faced several infrastructure and operational challenges that constrained efficiency and future scalability.

A heterogeneous server environment consisting of approximately 385 ageing systems increased operational complexity and management overhead.
Critical banking applications required consistent high performance, low latency and uninterrupted service availability.
Rising energy consumption and cooling requirements were driving infrastructure operating costs and affecting sustainability objectives.
Diverse workload requirements spanning core banking, middleware applications, reporting platforms, analytics tools and cloud-native services required a highly flexible architecture.
Existing infrastructure lacked the scalability and efficiency needed to support future AI and machine learning initiatives.
Multiple hardware generations created challenges related to maintenance, supportability and lifecycle management.
The client required a modern infrastructure platform capable of delivering substantial consolidation while maintaining performance, reliability and regulatory compliance.

The Objective

HCLTech worked closely with the client to define a strategic infrastructure modernisation roadmap designed to improve operational efficiency and support future growth.

Key objectives included:

Consolidate the existing server estate into a significantly smaller infrastructure footprint.
Increase compute density and performance while maintaining support for all existing workloads.
Improve performance per watt and performance per dollar across the data centre.
Reduce total cost of ownership through lower power, cooling, maintenance and infrastructure management costs.
Standardise infrastructure to simplify operations and reduce administrative complexity.
Build a scalable foundation capable of supporting future analytics, machine learning and AI use cases.
Use data-driven assessment and sizing methodologies to optimise hardware selection and workload placement.

The Solution

HCLTech designed and deployed a unified infrastructure architecture powered by next-generation Intel Xeon processors.

The new environment replaced approximately 385 legacy servers with 107 modern enterprise-class systems engineered to support business-critical banking workloads. The architecture leveraged high-core-count processors, DDR5 memory, enhanced security capabilities and built-in AI acceleration technologies to maximise performance and efficiency.

Using advanced infrastructure assessment and workload analysis tools, HCLTech evaluated workload characteristics, utilisation patterns and future capacity requirements. This data-driven approach enabled accurate server sizing and helped identify the optimal deployment configuration for each workload category.

The solution included:

High-density compute platforms supporting significantly greater workload consolidation.
DDR5 memory technology delivering higher bandwidth and increased application performance.
Built-in AI acceleration capabilities enabling support for future machine learning and generative AI workloads.
Enterprise-grade resilience and security capabilities to meet banking industry requirements.
High-speed networking and storage connectivity designed for transaction-intensive environments.
Standardised infrastructure architecture simplifying management and lifecycle operations.

To minimise risk, HCLTech executed the migration through a phased deployment model. A parallel infrastructure environment was established where applications and data were replicated, synchronised and validated before production cutover.

Comprehensive validation activities were performed throughout the programme, including application compatibility testing, performance benchmarking, peak-load simulations, failover testing and operational readiness assessments. This structured approach ensured business continuity while enabling a smooth migration to the new infrastructure platform.

Technologies leveraged: Intel Xeon processors, DDR5 memory, AI acceleration technologies, enterprise Linux platforms, virtualisation technologies, OpenShift container platforms and infrastructure assessment tools.

The transformation delivered measurable business value across performance, efficiency, sustainability and future readiness.

72% server estate reduction through consolidation from approximately 385 servers to 107 modern enterprise systems.
3.6x infrastructure consolidation ratio enabling greater workload density while maintaining support for all business-critical applications.
40% increase in average application throughput across key banking and enterprise workloads.
30% to 40% faster execution times for complex business processes, reporting workloads and transaction-intensive operations.
86% reduction in power consumption with estimated maximum power demand decreasing from approximately 154 kW to 21.4 kW.
86% reduction in annual energy consumption resulting in substantial reductions in utility and cooling costs.
86% reduction in data centre footprint with rack space requirements decreasing from approximately 770 rack units to 107 rack units.
4.5x increase in memory capacity from approximately 49 TB to 219 TB, supporting higher workload density and future scalability.
Approximately 40% reduction in five-year total cost of ownership through lower infrastructure management costs, energy savings, maintenance efficiencies and platform standardisation.
AI-ready infrastructure across the entire environment enabling future machine learning, inference, analytics and generative AI applications without requiring dedicated AI appliances.
Improved sustainability outcomes through significant reductions in power consumption, cooling requirements and overall carbon footprint.
Enhanced operational efficiency through a standardised infrastructure platform that simplifies administration, patching, monitoring and lifecycle management.

By combining strategic infrastructure modernisation with advanced Intel technologies, HCLTech helped the client create a high-performance, secure and energy-efficient platform capable of supporting critical banking operations today while providing the flexibility required for future innovation. The transformation established a robust foundation for digital growth, improved operational efficiency and long-term business resilience.
