Server room refresh

Let’s face it, you’ve probably seen (or overseen) a server room that keeps you up at night. From messy, tangled cabling and untraceable connections to improperly installed equipment and poor ventilation, it can truly be the thing of nightmares.

Not only equipment problems haunt the server room—basics as obvious as trash, unlocked doors and windows letting in sunlight (not to mention lack of security!) create an inefficient and unsafe environment for sensitive equipment. This can result in downtime, equipment damage and loss of data paramount to running your operations. 

Click each of the hot spots below to learn more about server room refresh best practices and how Eaton can help make yours a dream come true.

Clean floor
Keep floor free of trash and debris (including your Crocs) to eliminate tripping hazards.
Hot tip: Carpet absorbs heat—use raised floor tiles to increase ventilation and decrease heat absorption.
Extra batteries & storage
Batteries should be ordered when needed, not stored for long periods. When extras are on-hand, keep them in secure storage and never stacked on top of each other.
Fire extinguisher & sprinkler system
While fire safety is of great importance, it’s also important to keep the fire extinguisher and ceiling sprinkler system away from sensitive electronics.
Cabling
Not only will you sleep better at night knowing where each connection leads, a clean, clearly labeled rack reduces clutter and accidental disconnections.
Hot tip: Cleaning up that mess of dangling cables improves airflow and helps eliminate overheating in the rack, resulting in longer equipment lifespan and reduced downtime!
Cable management
Take the edge of upgrades and maintenance by keeping cables organized from the get-go! Cable trays and ladders provide efficient and safe organization while increasing airflow within the rack.
UPS placement
Start with the heaviest equipment at the bottom—that means your UPS! Work your way up and place less power-intensive equipment (with less heat draw) toward the top.
Redundant power
Redundant power is reliable power—use an automatic transfer switch (ATS) to power devices from two sources should one source fail—meaning no interruption to connected equipment.
Daisy chaining power & surge strips
There’s no need to plug a surge protector into a UPS, in fact it may cause improper load balancing and cause an overload to the UPS circuit.
Extremely hot tip: Never, ever plug a space heater into a surge protector! Space heaters draw a significant amount of power and can easily overload the circuit, leading to electrical hazards and fire!
Rack storage & security
Make a plan when populating racks, including placing heavier equipment at the bottom and leaving space for future growth. (Not pictured: secure your equipment with locking rack doors!)
Windows
You might like a view from your workstation, but your servers do not. Avoiding windows in your server room helps eliminate security risks and prohibits light and heat from damaging equipment.
Door security
Your equipment deserves an on-site security guard, but a closed, locking door will have to suffice. Key-free biometric locks provide easy, secure access and peace of mind.
Sensitive information
Even if you are the only person managing the server room, it’s imperative that you do not leave sensitive information and peripherals in the open.
Cooling
It takes much more than a floor fan to keep power hungry devices cool! In-row cooling provides primary, close-coupled cooling with remote management capabilities, eliminating the need for on-site monitoring.
Hot tip: Add an environmental sensor to monitor temperature, humidity and contact-closure inputs, including smoke detectors, fire alarms and security systems!

How to take your server room from nightmare to a good night's sleep

Environment

The first thing to do is assess the physical space—where are entryways, windows, ducts and lighting? Where is your power source and is it accessible for equipment connection? Answering these questions from the start will help you build out your current infrastructure and plan for future growth.

  • Floor should have sufficient capacity to handle the pressure of heavy racks and the equipment they house; server rooms should ideally not be in basements or top floors to avoid leaks and moisture.
  • Server room should have no exterior walls—insulated walls with buffer between exterior-facing walls helps protect against heat and natural disasters.
  • Ceiling height must be able to accommodate standard rack heights while still allowing ample space for duct work and cable management above server racks. 

Power

Server rooms contain mission-critical equipment and require UPS systems to ensure continuous power. Not only will you get peace of mind when power outages occur, UPSs also provide protection against power fluctuations and surges.   

  • Find the right size—and placement—for UPSs. Not only should power protection be placed in cool, dry, and well-ventilated racks, it’s important to start installation with the heaviest equipment (UPS batteries) at the bottom of the rack.
  • Conduct regular battery testing and maintenance to ensure UPSs are functioning and batteries are ready when needed. 
  • Redundancy is key! In the event of power failure and failure of the primary UPS, an automatic transfer switch (ATS) provides a reliable means of transferring loads between primary and alternate sources of power. 

Storage 

Proper server rack installation and management is crucial for efficient operation, safety and organization of racks and the equipment they contain. 

  • Use consistent configurations to simplify management, improve airflow and enhance cooling efficiency, including standardizing on racks and cable management solutions. 
  • Implement structured cable management to avoid tangling, improve airflow and facilitate easy maintenance. Color coded cables and cable organizers help maintain a neat and accessible setup. 
  • Ensure aisles and spaces around racks are kept clear for easy access during maintenance and emergencies; utilize hot aisle/cold aisle containment to optimize cooling and energy efficiency. 

Cables & Cable Management

The server room is your control center where every connection counts—make sure you can find each cable and where it leads! Efficient routing and organization in paramount to keeping control of your power and data. Starting with a connection map helps identify every connection, especially problem areas. 

  • Properly managed networking and power cords prevent overheating by allowing ample airflow through the rack and around mounted equipment.
  • Labeled and organized cables make it easy to identify where each connection leads, helping resolve issues quickly when a connection is lost.
  • Neatly arranged cables (at the right length!) enhance safety, reducing the risk of tripping hazards and electrical shorts.

 

Security 

Keep security in mind from the very start! You may be concerned with handling essential data, but don’t forget the physical security required to keep sensitive data in the right hands. In addition to cameras in front of and within your server room, it’s good practice to limit access to only necessary staff. 

  • Prevent unauthorized access to the room by implementing key card access or modular access control systems, like a fingerprint door scanner, to control and monitor who access the server room. 
  • Use locking racks to prevent unauthorized access to individual racks; installing rack door sensors is an additional step to detect and alert on any physical access. 
  • You might like a room with a view, but your servers do not! Whenever possible, utilize a room without windows to eliminate an additional access point as well as heat source. 

Cooling 

Maintaining safe temperatures is critical to the operation of your server room. Depending on your room size and the equipment installed, building HVAC may not cut it (and shouldn’t be run 7x24 anyway!) The ideal temperature should be between 68 and 72 degrees, but there are other environmental aspects to keep in mind as well.  

  • Best practices for maintaining optimal temperature include keeping space between servers and cabling in racks, installing fans to mediate heat and, of course, installing in-row, rack-based or portable cooling.
  • In-row cooling, pictured, provides precision cooling in a row-based form factor that occupies very little floor space; ideally sized for your small-to-medium data center at virtually any density, saving you the cost of a raised floor or new installation.
  • Environmental sensors provide remote temperature/humidity monitoring, with remote status on contact closure, including smoke detectors, fire alarms and security systems.
