Top Server Room Cooling Mistakes and How to Avoid Them

Balaji Perumal

Maintaining strict temperature control in server rooms and data centers is critical for IT infrastructure and operations. However, ineffective cooling strategies end up costing companies thousands in waste, downtime and equipment damage each year. To maximize efficiency, uptime and cost savings, avoid these top server room cooling mistakes:

Failing to Monitor Temperature and Humidity

Not installing remote environment sensors like the Tempcube in server rooms means lacking visibility into fluctuations that damage IT infrastructure. Precision temperature monitoring using devices designed specifically for server rooms provides 24/7 monitoring to avoid overheating events, minimize downtime risks and ensure stable cooling.

Relying on Improper Cooling Technology

IT server rooms require highly efficient cooling systems to remove heat loads from high-density equipment. Mismatched or undersized HVAC units will not effectively regulate temperatures and humidity levels. Choose and install server room-rated cooling technology with guidance from IT and HVAC professionals. Precision cooling units like in-room CRACs or CRAHs maintain tight ranges.

Neglecting Heat Load Planning

Failing to calculate server room heat loads based on equipment types and densities hampers the ability to select cooling technology with sufficient capacity. IT and HVAC teams must collaborate to determine heat load requirements, factoring in perforated floor tiles, rack placement and server capacities. Oversized cooling systems waste energy while undersized systems will not maintain optimal ranges.

Inadequate Hot Aisle/Cold Aisle Layout

Without a strategic hot aisle/cold aisle equipment layout, cooling air does not circulate properly, leading to server overheating and energy waste. The layout separates cold supply and hot exhaust airflow to maximize cooling efficiency. It allows cold air to reach and extract heat directly from server intakes. Optimize layout based on your Tempcube readings for temperature balance.

Lacking Separation from HVAC

Combining cooling for IT server rooms and other building areas compromises temperature regulation. Server room HVAC systems should be separate from general building controls to enable precise management of ranges like 18 to 27 degrees C recommended by ASHRAE for data centers. Isolated controls reduce risks of downtime from temperature swings when other facility systems active.

Disabling Fan Speed Controls

Lacking the ability to automatically control or manually adjust fan speeds based on changing heat loads reduces cooling efficiency, wastes energy and prevents optimizing airflow for temperature balancing detected by your Tempcube system. Choose cooling technology with built-in fan speed controllers or install control modules for adjustable speed fans using sensors to monitor changing needs.

Minimizing Costs Using Inefficient Practices

Some IT organizations focus excessively on minimizing capital expenditures for server room cooling, choosing undersized or inadequate technology, skimping on precision sensors or professional installation services. However, the costs of downtime, damage and excess energy usage from inefficient cooling rapidly outweigh any initial savings. Invest in proper design and equipment for server environments to maximize operation budgets long-term.

With the right cooling strategy using input from IT and HVAC experts, the appropriate technology for heat loads, precision temperature monitoring with devices like the Tempcube and vigilance for any risks to ranges, organizations benefit from optimized server room cooling. Stable environments reduce waste, cut costs and maximize continuity for revenue streams increasingly dependent on IT infrastructure and online data access. Precise cooling saves money and may just save the day.

Top Mistakes to Avoid: A Summary

To optimize server room cooling, avoid these common yet costly mistakes:

1. Lack of precision monitoring using solutions like the Tempcube to provide real-time visibility into temperature fluctuations that damage IT systems. Continuous oversight is required.

2. Improper or inadequate cooling technology without the capacity to maintain strict temperature and humidity control for server room heat loads. Choose commercial-grade, server room-rated cooling systems with guidance from IT and HVAC professionals.

3. Neglecting to calculate current and future server room heat loads that must be removed to determine necessary cooling capacities. Heat load planning should factor in server specifications, layout, perforated floor tiles and rack placements.

4. Inefficient hot aisle/cold aisle layouts preventing maximum cooling from reaching server air intakes. Strategic layouts separate hot and cold airflows for optimal circulation. Adjust based on Tempcube sensor mapping for any hotspots.

5. Combining server room cooling with general building HVAC that lacks the precision required and risks downtime from fluctuations. Server environments demand separate, tightly controlled systems.

6. Disabling fan speed controls reduces the ability to optimize circulation and airflow based on variable server room heat loads. Choose technology with adjustable speed fans and automation controls.

7. Focusing excessively on minimizing short-term costs by purchasing inadequate cooling technology, systems without precision sensors or professional design services. The total costs of inefficient environments outweigh any initial savings from subpar equipment or installation.

With the right strategy and partnerships, server room cooling operates at maximum efficiency based on heat load planning, specialized technology, isolated controls, and precision management systems like the Tempcube that provide continuous monitoring and mapping for optimized airflow.

An efficient server room cooling strategy saves exponentially more in waste, downtime, and long-term budget requirements - a small price for systems securing digital infrastructure and capabilities on which businesses increasingly depend.

Mistakes Made: The High Cost of Poor Cooling

The consequences of inefficient server room cooling include:

•Hardware damage and shorter IT equipment lifespans from overheating. Harsh temperature fluctuations accelerate component decay.

•Loss of productivity from slow software and applications. High heat reduces processing power and impacts performance.

•Higher costs for replacement components that fail prematurely due to overheating events.

•Increased risk of data loss or corruption from downtime events caused by excessive temperatures or cooling failures.

•Greater energy usage and costs required to run cooling units struggling to regulate harsh server room temperatures. Excess waste in powering inefficient systems.
