Choosing an Environmental Monitoring System for Your Server Room

Server rooms and data centers are at the heart of many enterprises. Maintaining servers so that they stay operational is a necessary cost of doing business in the digital age. Without the right tools, it is impossible for a company to keep servers operational long-term. The financial impact of failed servers can be substantial, not just in terms of new hardware but in terms of downtime and lost opportunities.

All of the tools on this list can be used to monitor server rooms against excessive heat or performance issues that could damage them over time. Products like netmon, Paessler PRTG Network Monitor, and Monnit provide a centralized perspective of your data center so you don’t miss out on any conditions that could affect performance.

If you’re unsure which tool to purchase we recommend a product that has automated alerts. Alerts will flag when there is a problem with your system so that you don’t have to manually catch every performance problem that occurs.

Server Room Environmental Monitoring Systems FAQs

Why is it important to keep your server room cool?

Servers heat up while they are running – that is to be expected. However, if a server gets too hot, physical damage can occur. If your server room has many servers in it, the collective heat of these machines will cause the temperature of the room to rise. The total heat within the room will mean that the cooling systems within each server will be sucking in warm air, making the onboard heating problem worse. Keeping the server room cool provides cold air to the onboard cooling systems of servers.

What humidity level should a server room be at?

The measurement for server room humidity is called “relative humidity” (rH). This is expressed as a percentage and it should be at 40 to 60 percent. If rH is too low, static will build up, if rH is too high, moisture will condense into water within the servers and other equipment in the room, which could lead to shorting.

At what temperature do servers fail?

The critical components servers are the CPUs. These have onboard thermometers that will trigger a shutdown or a speed reduction if the temperature gets too high. This point is called the TJunction or TJMax. Each processor type has a different TJMax level. For Intel processors, this is around 100 degrees Celsius and for AMD processors it is around 90 to 95 degrees Celsius.
