7 Server Room Tips to Improve Performance and Save Money

Between rising energy prices and growing rack densities, server rooms are struggling to maintain optimal performance without breaking the bank. As a supplier of critical IT solutions, we hear from plenty of server room managers searching for ways to improve efficiency and cut costs in their facility, but they are not sure where to even start. We’ve helped countless managers optimize their server room with our expertise and reliable equipment.  Here are seven tips we recommend server room managers adopt to save money on their operations:

• Optimize your server room layout
• Update power distribution equipment
• Organize your server racks
• Choose the right cooling solution
• Use modern servers
• Invest in regular preventive maintenance
• Monitor everything to prevent surprises

Let’s get started by diving into the most reliable ways to improve your server room’s performance:

Tip #1: Optimize Your Server Room Layout

Having the right cooling system will do little to prevent expensive overheating if your server room is not laid out to encourage airflow. Even if you use liquid cooling for your server racks, it’s likely you will still use air cooling to maintain the rest of the room at an ideal temperature. After all, when hot air can’t be effectively removed from your data center server room, hotspots will occur and equipment in those areas will overheat.

To combat the risk of hotspots in your server room, hot and cold aisles must be implemented. This means arranging server racks front-to-front and back-to-back, so every equipment intake faces a cold aisle and every exhaust discharges into a hot aisle. Keep aisles and rack faces unobstructed so air moves freely and heat has a clear path out.

From there, containment is where the real savings live. Adding physical barriers to stop hot exhaust air from circling back around into the cold aisle lets you raise supply air temperature without risking equipment. This is often the single cheapest efficiency win available. Rearranging racks costs nothing but labor, and containment panels and brush grommets for cable cutouts are inexpensive compared to what they save your cooling system.

Tip #2: Update Power Distribution Equipment

Power distribution units (PDUs) can help deliver energy to your equipment, but they can also waste your energy. Every time electricity moves through a power chain, a portion of it is lost to heat. Those losses show up twice on your bills: first as wasted electrical energy and second as extra heat your cooling system must remove.

Updating aging or mismatched power distribution equipment will help improve performance and reduce operating costs. The largest conversion losses in your power chain sit in the UPS and any step-down transformers, so start there. A modern UPS running in a high-efficiency mode can cut those losses substantially compared to an older double-conversion unit. At the rack, the case for upgrading is visibility and control rather than raw capacity: older PDUs typically lack outlet-level metering, remote switching, and support for the higher-voltage distribution that dense racks increasingly require.

Tip #3: Organize Your Server Racks

Your facility needs server racks to house all your critical equipment, but that doesn’t mean you can just cram everything into one containment unit. In fact, even if you only need one server rack for a few devices, you could still risk overheating everything without the proper organization. Not only that, but keeping your server rack orderly will help you access specific devices when you need them and make it easier to perform maintenance. Some of the most common tools used to prevent overheating include blanking panels, cable management, and side air dams that seal the gaps between equipment and rack rails. When paired with scalable rack designs, these solutions effectively encourage airflow and leave room available for future equipment.

Tip #4: Choose the Right Cooling Solution

Cooling systems play a vital role in improving efficiency in server rooms by preventing overheating. However, the wrong cooling system can cost your facility greatly by being either undersized or oversized. Undersized equipment leaves you fighting hotspots; oversized DX equipment short-cycles, which wastes energy and shortens compressor life. Determining the right cooling solution for your server racks depends on the size of your space, the number of devices you have, how everything is laid out, and more. Luckily, there are several cooling solutions that can fit various environments, such as:

Row Cooling

Multiple server racks should be placed in rows to keep them organized and reduce the chances of hotspots from warm air. However, it can be difficult for traditional air conditioning units to cool server racks in these rows. This is where row-based cooling comes in. These cooling units are installed in the rows themselves, delivering cold air right where your server racks need it instead of mixing with hot air and failing to regulate temperatures. As a result, cooling is more direct, efficient, and helps you use less energy since it does not have to blow cold air all around the server room.

Rack Cooling

But what if your server racks contain high-density equipment generating more heat than row cooling can keep up with? Rack-based cooling provides a solution. This equipment mounts directly on or inside the rack most commonly as a rear-door heat exchanger. Exhaust air is then captured the moment it leaves the servers and removes the heat before it ever reaches the room. Because the air path is so short, hot air never gets the chance to recirculate or mix, which is what creates hotspots in the first place. Rear-door units are typically liquid-based, and depending on the model can handle well beyond what row cooling supports. Less heat in the room means less reliance on traditional air conditioning and fewer overheating-related outages.

Liquid Cooling

As rack densities climb into the tens of kilowatts, it’s worth evaluating whether air-based cooling can still keep pace. With good containment, in-row systems handle high-density racks effectively. The Vertiv™ CoolPhase Row, for instance, supports up to 40kW. Past that range, direct-to-chip and immersion cooling become the more efficient path, moving heat away at the component level instead of relying on air as the transfer medium.

There’s no single density number that triggers the switch. It depends on how well your aisles are contained, what supply air temperature you’re running, and how much floor space you have to work with. Adopting liquid cooling also doesn’t mean abandoning air cooling — most facilities integrate the two, since supporting equipment still needs conditioned air. And liquid systems bring their own considerations: CDU and pump reliability, plus leak detection, which we’ll cover below.

Tip #5: Use Modern Servers

Your old servers were built to handle your needs years ago. But it’s likely that your facility’s needs have changed, especially when it comes to power consumption. In fact, in August 2026, the U.S. Energy Information Administration forecasted that electricity sales to the commercial sector will rise 3.5% in 2026 and 4.1% in 2027. Industrial sector sales are also projected to grow 2.1% in 2026 and 3.9% in 2027. That’s a sharp break from the prior two decades when U.S. electricity consumption stayed essentially flat.

As electricity costs climb, the performance you get per watt matters more than it used to, and older servers deliver far less of it than current hardware. Modern servers are also rated for wider temperature ranges. ASHRAE’s recommended envelope runs 18–27°C (64.4–80.6°F), but most current equipment carries an allowable rating well above that, meaning you may be cooling your room harder than your hardware actually requires. This allows server room managers to reduce cooling system efforts, which can quickly become expensive.

Tip #6: Invest in Regular Preventive Maintenance

Server rooms are only efficient if the equipment in them is properly taken care of. This doesn’t just mean reacting to issues but performing preventive maintenance that will keep every device running smoothly and stop issues before they arise. Strong preventive maintenance plans should include the following:

Regular Cleaning

Accumulating dust and debris can slow down operations or even damage equipment. As a result, regular cleaning should be performed by professionals to keep all devices pristine and able to run smoothly. This includes server racks and cabinets, generators, cables, switches, wire connectors, filters, and more. Due to the sensitivity of your equipment, cleaning should always be performed by an expert technician to prevent accidental damage to your devices and surprise downtime.

Replace Hardware Components

Just because your server racks are running smoothly right now doesn’t mean every component in them is working optimally. Wear-out components like batteries, fans, capacitors, and filters degrade gradually and give you warning if you’re looking for it. Other failures arrive without notice, which is why regular hardware evaluation and redundancy work together rather than substituting for one another. This way you can preemptively replace equipment and schedule downtime to do so, rather than being forced into unplanned shutdowns and emergency replacement costs.

Keep Software Updated

When server application and monitoring software is out of date, your entire server room is at risk of slowed operations and cyberattacks. That’s why it’s important for server room managers to regularly check for software updates. You should also check to see if you can automate software updates or if they need to be performed manually. Either way, routinely checking your software to ensure you have the latest version will help keep your server room running smoothly.

Tip #7: Monitor Everything to Prevent Surprises

It only takes one piece of faulty equipment to force your server room into unplanned downtime. The good news is that a large share of failures announce themselves first. For example, batteries lose capacity, fans slow down, and temperatures drift, but monitoring catches those signals early enough to act on them. Continuous monitoring won’t prevent every sudden failure, but it converts most of them from emergencies into scheduled work. This requires reliable monitoring and management solutions that can report on the following:

• Battery health: Backup batteries degrade whether or not you use them — capacity fades and internal resistance rises with age, and VRLA strings typically need replacement every three to five years. Monitoring reveals actual remaining capacity, so you replace on evidence rather than guesswork or a calendar date.
• Environmental conditions: Improper temperature and humidity levels wreak havoc on your server operations. Monitoring systems let you know the minute something in your environment isn’t right.
• Leak detection: Water or liquid leaks from cooling systems in your server room will severely damage your equipment, which is why it’s important to catch these issues early on.
• Power system metrics: When you know how much electricity your servers and equipment are using, you can better identify and prevent overloads or irregular power quality.

A data center server room shouldn’t be left to run on its own. If you don’t know how every piece of equipment is performing, you can’t optimize your operations or proactively prevent issues. But when you get alerts the minute something doesn’t look right, you can plan how to fix the problem instead of reacting to sudden, expensive disasters.

Server Room Performance FAQs

How can I reduce energy costs in my server room without sacrificing performance?

The most effective way to lower energy costs in a server room is to improve visibility and eliminate waste. Smart power monitoring, modern servers, organized server rack configurations, and right-sized cooling systems work together to reduce unnecessary power draw. In a data center server room, small inefficiencies multiply quickly, so identifying waste at the rack level makes a measurable difference.

What is the fastest way to improve efficiency in an existing data center server room?

Start with monitoring and airflow management. Many data center server room inefficiencies stem from poor visibility and disorganized rack layouts. Installing smart PDUs, adding blanking panels to every server rack, and correcting hot and cold aisle containment can immediately reduce cooling strain and operating expenses.

How do I know if my server rack layout is costing me money?

If you have tangled cabling, missing blanking panels, blocked airflow, or inconsistent rack densities, your server rack configuration is likely forcing your cooling system to work harder. Over time, that increases both energy costs and equipment wear. A rack audit can quickly reveal hidden inefficiencies.

Is upgrading power distribution really worth the expense?

Yes, especially in older server rooms. Outdated PDUs lack monitoring and may waste power through inefficiencies. Modern smart PDUs give real-time insight into load levels inside each server rack, helping you balance circuits, prevent overloads, and reduce wasted energy in your data center server room.

How often should preventive maintenance be performed in a server room?

Preventive maintenance should be scheduled at least annually, and in higher density environments, quarterly inspections are recommended. Dust buildup inside a server rack, neglected filters, or aging batteries can all increase energy use and risk downtime. Consistent maintenance reduces emergency repair costs.

When should I replace older servers to improve efficiency?

If your servers are more than five to seven years old, they are likely consuming more power than modern alternatives while delivering less performance. Newer equipment in your server rack often operates at higher allowable temperatures, reducing cooling requirements in your data center server room.

How can monitoring systems help reduce server room expenses?

Monitoring reveals inefficiencies before they become expensive problems. Tracking environmental conditions, battery health, and rack level power usage allows server room managers to make informed adjustments that reduce waste and prevent downtime across the entire data center server room.

What is the most overlooked cost driver in a data center server room?

Power loss in the distribution chain is frequently overlooked. Every transfer of electricity generates heat. Inefficient or outdated distribution equipment inside your server room adds both electrical waste and additional cooling demand. Upgrading infrastructure often delivers faster ROI than expected.

How can I plan for future growth without increasing costs today?

Choose scalable server rack designs and modular cooling systems. This allows you to expand capacity gradually without oversizing infrastructure. In a growing data center server room, planning for density and airflow now prevents expensive retrofits later.

What is the best first step if I want to reduce server room operating expenses this year?

Conduct a comprehensive assessment of your server room, including rack organization, power distribution, cooling efficiency, and monitoring capabilities. Identifying inefficiencies at the server rack level typically reveals quick wins that reduce expenses across your entire data center server room.
