Raise your hand if you’ve seen a server stuck in a closet next to cleaning supplies, whirring away as dust gathers around it. It’s an all too common sight at small or medium-sized businesses, and even in branch offices of large businesses – and it’s dangerous.

Not necessarily dangerous to employees, but dangerous to the business. Because IT equipment is no less important for SMBs as it is for enterprise companies, and equipment in branch offices should be protected just as IT infrastructure installed in a data center is.

Here’s a little checklist that may help you determine whether your IT gear is installed in a less-than-optimum fashion.

Virtually all small server rooms need an uninterruptible power supply (UPS) and power distribution unit (PDU). Note that a UPS with capacity above 2,200VA cannot be plugged into a household socket – it needs a higher rated socket or can be hardwired to an electrical panel by an electrical contractor. The PDU decreases the required wiring distance and allows several devices to be powered by a single source. Your best bet is to use UPSs and PDUs that can be remotely managed, so they provide alerts when things go wrong and enable remote administrators to shut down particular outlets, such as to restart a hung server.

You’ve got multiple cooling options, depending mainly on the amount of IT equipment you’ve got and where it’s located. In some cases, the room air conditioning will suffice; in others you need dedicated cooling. Here’s a simple guide:

  • IT loads less than 400 watts: use conduction, where heat can flow freely through the walls
  • IT loads between 400 and 700 watts: use passive ventilation in which heat can flow into cooler air via a vent or grille, without use of a fan
  • IT loads between 700 and 2,000 watts: use fan-assisted ventilation
They improve availability, organisation, cable management, physical security, cooling effectiveness, power distribution and just the professionalism associated with the overall look of an IT space. You can even get racks that are designed for an office environment, providing a soundproof, powered and ventilated IT enclosure.

Physical Security and Monitoring
The biggest threat to IT infrastructure is human error Mislabelled equipment, spilled coffee and other such mishaps routinely cause operational issues and even complete IT failures. You can (largely) avoid such issues by locking your server closet or rack enclosure, ensuring only authorised personnel can access IT equipment. Security cameras and sensors that detect smoke, temperature, humidity and movement are also good ideas.

Effective lighting is often a problem in small IT environments, making it difficult to see product labels and wire connections. But there’s a simple, inexpensive solution: a headlamp. This will allow hands-free visibility in tight spaces and is less likely to be lost, damaged or removed from the room.

Software Management Systems
All kinds of software is now available to help manage small server sites from afar. The tools enable everything from the unattended, graceful shutdown of servers after a power outage to energy usage reporting and risk assessments. Tools are also available to help you configure your environment and determine which products are the best fit.

An IT environment that is chaotic, unsecure, unmonitored and cramped can lead to significant downtime and inconvenience. Follow these recommendations to optimise your operations and ensure the security of your business-critical IT infrastructure.
