Project Background
Data Center Infrastructure (DCI) in Chennai plays a vital role in providing high-performance data services to businesses, particularly in a region where secure and reliable connectivity is essential for global and local companies. One of the key challenges in delivering uninterrupted services is establishing robust connectivity between critical network points, such as cable landing stations (CLS) and data centers. This project focuses on enhancing the connectivity between the Chennai Cable Landing Station (CLS) and the Ambattur Data Center, a crucial link in facilitating high-speed data transmission across regions. To ensure seamless, high-availability connectivity, a three-path fibre-optic solution with redundancy was implemented, designed to meet strict performance standards, support future traffic growth, and minimize the risk of service disruptions.
Challenges Faced and Mitigated
● Geographical and Environmental Challenges
● Ensuring Redundant and Independent Fibre Paths
● Regulatory and Compliance Issues
Geographical and Environmental Challenges
Challenge: The deployment of fibre-optic cables from the Chennai CLS to the Ambattur Data Center was complicated by urban infrastructure, such as roads, buildings, and other utilities. The geographical constraints made the task of laying down fibre-optic cables challenging, especially since the cable routes needed to avoid high-traffic areas and existing infrastructure.
Mitigation: We conducted a thorough survey and route analysis to ensure the most efficient cable pathways while minimizing disruption. Several alternative routes were explored, ensuring that the fibre optic cables were laid out across optimal paths. For particularly difficult terrains, they utilized horizontal directional drilling (HDD) and trenchless technology to minimize the impact on the surrounding environment and infrastructure. Additionally, cooperation with local authorities helped smooth over any regulatory hurdles related to construction and roadwork permits.
Ensuring Redundant and Independent Fibre Paths
Challenge: Achieving true path redundancy was critical, as it meant designing a system where a failure on one path would not disrupt overall connectivity. However, creating completely independent and separate paths while maintaining high performance was a significant challenge.
Mitigation: The team devised a strategy to create three entirely independent fibre-optic paths that would not share any common infrastructure, such as cable routes or access points. This approach ensured that any issues with one fibre path, such as accidental cuts or damage, would not impact the others. Each path was carefully routed through distinct, geographically separated regions to mitigate the risk of simultaneous failure due to external factors like natural disasters or construction activities. This design ensured that there would be no single point of failure, making the system highly resilient.
Regulatory and Compliance Issues
Challenge: Ensuring compliance with local regulatory frameworks, including telecommunications, environmental, and construction laws, was another challenge. Regulatory approval and adherence to national and international standards were mandatory for the successful deployment of fibre-optic connectivity.
Mitigation: We worked in close partnership with legal teams, local authorities, and regulatory bodies to ensure that all required permits and approvals were secured. This involved a comprehensive assessment of the environmental impact, followed by adherence to telecom industry regulations. The team ensured that all construction practices followed local zoning laws and environmental guidelines, minimizing any potential risks or delays.
Our Approach & Solution
We took a systematic approach to design and implement the high-performance, redundant, and scalable fibre-optic connectivity solution between the Chennai Cable Landing Station (CLS) and the Ambattur Data Center. The project was broken down into multiple stages, ensuring that each step was completed with precision and minimal disruption. Below is a detailed overview of the solution:
Route Survey and Planning: Our first step was to carry out an exhaustive survey of both the Chennai Cable Landing Station and the Ambattur Data Center. The goal was to map out the most effective fibre routes that avoided congested areas and took into account terrain challenges. The routes were designed to minimize the risk of damage and interference from urban infrastructure while maximizing the overall resilience of the network.
Design of Three Independent Fibre Paths using Google Route/KML file: A key element of the solution was the creation of three independent fibre-optic paths. Each path was designed to be geographically distinct, using different routes to ensure redundancy.
Fibre Installation: During installation, we utilized advanced techniques like trenching and horizontal directional drilling (HDD) for areas where traditional digging was not possible. The installation team ensured that the fibre was carefully laid, with attention to avoiding existing utilities and minimizing the impact on the local environment. The cables were laid with protective measures in place to avoid physical damage and were secured in durable conduit systems to provide extra protection.
Integration and Testing: Integration of the fibre-optic links into the data center’s infrastructure was done with minimal disruption. We conducted extensive testing of each fibre core and path for performance to ensure that all paths were functioning optimally and that the network was fully redundant.
The Impact
The successful deployment of the three-path fibre-optic connectivity between the Chennai Cable Landing Station (CLS) and Ambattur Data Center has provided a range of benefits:
Uninterrupted Connectivity and High Availability: The redundant fibre-optic paths ensure high availability and minimal downtime, even in the event of disruptions, accidental damage, or natural disasters. Customers can rely on the network for consistent performance without fearing interruptions.
Scalability and Future-Proofing: With high-bandwidth, low-latency connections in place, businesses have the flexibility to scale their operations as their data requirements grow. The design of the network allows for future upgrades without disrupting existing services, ensuring that the infrastructure remains relevant as demand evolves.
Improved Business Continuity: The network’s fault tolerance and redundancy improve business continuity by providing reliable disaster recovery options. Data can be securely transmitted between the CLS and data center without risk, supporting industries that require constant data access, such as finance, e-commerce, and cloud services.
Enhanced Client Confidence and Satisfaction: Customers now have confidence in the reliability of their data connections, knowing that they have provided them with an infrastructure solution that can support their business needs without compromising on performance or reliability. This builds trust and strengthens their position as a leader in data center services.
