What is IDA in Structured Cabling?

Data center structured cabling is a telecommunications cabling infrastructure consists of a number of standardized smaller elements. According to TIA-942 standard, a data center structured cabling system generally includes some key functional subsystems:

  • Entrance Room (ER)

  • Main Distribution Area (MDA)

  • Intermediate Distribution Area (IDA)

  • Horizontal Distribution Area (HDA)

  • Zone Distribution Area (ZDA)

  • Equipment Distribution Area (EDA)

Intermediate Distribution Areas (IDA), sometimes called intermediate distributors, are typically found in larger data centers with multiple floors or rooms that distribute fiber links from the MDA to various HDAs and EDAs via aggregation switches.

Importance of IDA

  • 1. Fiber Distribution: The IDA serves as a central point for distributing fiber links from the main distribution area (MDA) to various horizontal distribution areas (HDAs) and equipment distribution areas (EDAs). It ensures efficient and organized distribution of fiber connections throughout the data center.

  • 2. Scalability and Flexibility: As data centers grow and expand, the IDA allows for easy scalability. It enables the addition of new HDAs and EDAs without major disruptions to the existing network infrastructure. This flexibility ensures that the data center can adapt to changing needs and accommodate future growth.

  • 3. Simplified Cable Management: By consolidating fiber links and distribution points, the IDA simplifies cable management within the data center. It reduces the complexity of cable routing and makes it easier to identify and manage connections, reducing the risk of errors and improving overall maintenance efficiency.

  • 4. Network Performance: The IDA optimizes network performance by providing a centralized location for aggregation switches. These switches handle the distribution of fiber links and facilitate efficient data transmission between the MDA and various HDAs and EDAs. This centralized approach minimizes latency, improves bandwidth utilization, and enhances overall network reliability.

  • 5. Fault Isolation and Troubleshooting: The IDA enables better fault isolation and troubleshooting within the data center. By dividing the network into distinct distribution areas, it helps localize issues and minimize their impact on the entire network. This simplifies the identification and resolution of problems, reducing downtime and improving the overall reliability of the data center.

Best Practices for IDA Implementation

  • 1. Planning and Design: Before implementing an IDA, thorough planning and design are crucial. Understand the layout, requirements, and anticipated growth of the data center, ensuring that the IDA's location and capacity can meet future needs.

  • 2. Standardization and Labeling: Use standardized equipment, patch panels, and labeling systems in the IDA. This improves maintainability and management efficiency, making it easier to identify and track connections.

  • 3. Cable Management: Implement proper cable management practices to ensure the smooth operation of the IDA. Use appropriate cable trays, racks, and cable management accessories to ensure neat cabling and proper labeling. Regularly inspect and maintain cables to ensure connection quality and reliability.

  • 4. Security and Access Control: Securing the IDA is critical. Implement appropriate physical security measures such as access control systems, video surveillance, and fire prevention measures to prevent unauthorized access and potential physical threats.

  • 5. Redundancy and Backup: Consider implementing redundancy and backup strategies in the IDA to ensure high availability and fault recovery capability. Use redundant switches and power equipment and regularly backup and verify the configuration and data of critical devices.

  • 6. Documentation and Record Keeping: Establish detailed documentation and record keeping, documenting the layout, connections, and configuration information of the IDA. This simplifies troubleshooting, change management, and expansion planning and provides essential reference material for maintenance personnel.

  • 7. Monitoring and Alarming: Implement effective monitoring and alerting systems to continuously monitor the performance and operational status of the IDA. Use network monitoring tools and sensors to promptly detect and address any potential issues.

  • 8. Regular Maintenance: Perform regular maintenance and inspections, checking and cleaning equipment, cables, and connections in the IDA. Keep devices up to date and repaired and conduct periodic performance optimization and tuning.
