BULILDING SERVER ROOMS: BEST PRACTICES OF ELECTRICAL CONTRACTOR BLANCO ELECTRIC LTD
As an expert electrical contractor experienced with the construction of server rooms in the areas of Houston and Dallas, TX, Blanco Electric has evolved a set of procedures and best practices to complete a project in the shortest possible time and certainly within deadlines.
​
Our procedures involve several stages aiming at ensuring safety, sustainability, and optimal performance. The process may be modified from one location to another to adapt to specific requirements and circumstances.
​
Here is a step-by-step description of a typical server room construction process.
Project Preparation:
-
Requirements Gathering: Understand our client's needs, goals, and specifications. This includes the size of the server room, equipment to be installed, energy consumption, cooling requirements, and growth expectations.
​
-
Site Assessment: Inspect the location where the server room will be built, assessing the available space, power sources, and any potential environmental hazards.
​
-
Preliminary Design: Create an initial design of the server room, accounting for power distribution, cooling, structured cabling, and electrical redundancy. Consider energy efficiency, scalability, and ease of maintenance.
NOTES:
​
The preliminary design stage is crucial in setting the foundation for a successful server room project. It involves creating an initial outline of the server room, considering factors such as power distribution, cooling, structured cabling, and electrical redundancy.
​
These are the typical step-by-step actions involved at the preliminary design stage:
​
1. Define Server Room Requirements:
​
-
Determine the size of the server room based on the equipment to be installed, anticipated growth, and any client-specific requirements.
-
Estimate the power consumption of the servers and other equipment, which will inform the design of the electrical system.
-
Assess the cooling requirements, considering the heat generated by the equipment and the desired temperature and humidity levels.
2. Design Power Distribution System​
​
-
Plan the layout of the main distribution panel and subpanels, ensuring that they can handle the estimated power load and accommodate future expansion.
​
-
Identify suitable locations for uninterruptible power supplies (UPS) and backup generators, taking into account accessibility, maintenance, and safety requirements.
​
-
Consider power redundancy by designing two contingency plans, such as dual utility feeds, multiple generators, or UPS systems.
3. Design Cooling System​
​
-
Determine the type and capacity of cooling units needed to maintain the desired temperature and humidity levels.
​
-
Plan for air distribution by designing the placement of cooling units, vents, and ducts, as well as hot and cold aisle containment strategies.
​
-
Consider redundancy in the cooling system, such as having multiple cooling units or a backup cooling system in case of failure.
4. Design Structured Cabling System​
​
-
Choose the types of cables (e.g., copper, fiber-optic) based on the equipment, data transfer requirements, and scalability.
​
-
Design cable routing, including the placement of cable trays, runways, and raceways, ensuring efficient cable management and minimizing interference.​
-
Develop a labeling scheme for cables and network components to simplify maintenance and troubleshooting.
5. Consider Fire Protection and Security​
​
-
Plan for fire suppression systems, such as clean agent systems or inert gas systems, that are suitable for server room environments.
​
-
Design access control measures, such as electronic card readers or biometric systems, to restrict unauthorized access to the server room.
​​​
-
Incorporate intrusion detection systems, like surveillance cameras and motion detectors, to monitor the server room and alert security personnel of any unauthorized activity.
6. Review and Revise​
​
-
Review the preliminary design with the client and other project stakeholders, addressing any concerns or requests for changes.
​
-
Make revisions to the design as necessary, ensuring that it meets the client's needs and adheres to industry standards and best practices.
​
By following these steps, the preliminary design will lay a solid foundation for the detailed design and planning, construction, and installation stages of the server room project.
Detailed Design and Planning
-
Electrical System Design: Plan for power distribution, including the main distribution panel, subpanels, uninterruptible power supplies (UPS), backup generators, and power redundancy. Design for two contingency plans, such as dual utility feeds or multiple generators.
​
-
Structured Cabling Design: Develop a comprehensive plan for cable management, including cable trays, runways, and raceways. Determine the types of cables (e.g., copper, fiber-optic), cable routing, and labeling schemes.
NOTES:
​
A well-designed structured cabling system simplifies maintenance, reduces the risk of downtime, and allows for future expansion. Here are the detailed steps to create a comprehensive cable management plan:
​
1. Assess Equipment and Connectivity Needs​
​
-
Determine the types and quantities of network devices, such as switches, routers, and servers that will be installed in the server room.
​
-
Identify the required connections between these devices, considering factors like data transfer speeds, network architecture, and redundancy requirements.
-
Estimate the amount of cabling needed based on the equipment layout and the distances between devices.
2. Choose Cable Types and Standards​
​
-
Select the appropriate types of cables for the server room, considering factors like data transmission rates, distance limitations, and compatibility with existing equipment. Common cable types include copper (e.g., Cat 6, Cat 6a, Cat 7) and fiber-optic cables (e.g., single-mode, multimode).
​
-
Ensure that the chosen cables and connectors adhere to industry standards and best practices, such as ANSI/TIA/EIA and ISO/IEC.
3. Design Cable Routing and Pathways​
​
-
Plan the routes for cables to follow within the server room, ensuring they are organized, easy to access, and minimize interference with other equipment.
​
-
Determine the placement of cable trays, runways, and raceways, accounting for factors like load capacity, ease of installation, and future expansion.
​​​
-
Ensure that cable pathways avoid or minimize crossing with electrical conduits and HVAC systems to prevent interference or damage to the cables.
4. Plan for Cable Termination and Patch Panels​
​
-
Design the layout of patch panels and cable termination points, ensuring that they are easily accessible for maintenance and troubleshooting.
​
-
Plan for sufficient space around the patch panels to accommodate the bend radius of cables and facilitate cable management.
​
-
Incorporate cable organizers, such as cable managers, horizontal and vertical cable management bars, and Velcro straps, to maintain order and reduce stress on cable terminations.
5. Develop a Labeling and Documentation Scheme​
​
-
Create a consistent and clear labeling scheme for all cables, network components, and patch panels. This will simplify troubleshooting and maintenance tasks and reduce the risk of human error.
​
-
Document the cable management plan, including cable types, routing, termination points, and labeling information. This documentation should be easily accessible and regularly updated to reflect any changes made to the system.
6. Plan for Redundancy and Future Expansion:​
​
-
Incorporate redundancy into the cable management plan to ensure network reliability, such as having backup or diverse cable routes.
​
-
Design the cabling infrastructure to accommodate future growth, considering factors like additional equipment, higher data transfer speeds, and new technologies.
A comprehensive cable management plan provides an organized, efficient, and scalable structured cabling system for the server room. This ultimately contributes to the overall performance, reliability, and ease of maintenance of the server room infrastructure.
