High Density colocation enables customers to break the industry standard power cap of 4 kW per cabinet. Whether it's 40 1u servers or a full cabinet of blade chassis our high density cabinets are capable of 20 kW per cabinet allowing us to support your environment now and into the future.

Why is Density a challenge to host?

Historically data centers have allowed the hot air created by servers to be expelled back into the data center which contaminates the ambient air. Until today, the solution to hot air contamination has been to deliver colder and colder air at higher and higher velocities and enforce strict density limitations on customers in an effort to limit hot-spots. The downside of battling cold air contamination in this method is incredible inefficiency- often requiring data centers to utilize as much as 50% of their available power on data center cooling. Blowing colder and colder air at a higher and higher velocity has also made the data center a terrible place to work. The net result of this is your data center operator spends way more than they should to cool load that isn't enough to meet your needs, all the while creating a work environment that is inhospitable and still riddled with hotspots. Worst of all because of the strict density limits you're forced to add more cabinets than you need which complicates your environment and drives up your monthly hosting costs.

Why is High Density advantageous?

Today's highly capable servers, including blade centers, can be great for your IT environment. They're more scalable, easier to deploy and manage, and are more redundant. An added benefit is they allow you to consolidate many cabinets of older servers into a much smaller footprint freeing existing cabinets for growth or cage consolidation. Data centers were, and are still, being built to accommodate 4kW (36 amps @ 110v) making it nearly impossible to fully utilize your cabinets with even today's most basic server platforms. As a result you are forced to leave large amounts of cabinet space unused- space that you are paying for, driving up the cost per rack unit. This phenomenon will continue to get worse over time as servers get more powerful. Your footprint will get larger and larger while your cabinet utilization gets less and less, driving up costs until they become unsustainable. And that's today, what about tomorrow?

The NAC Approach

Net Access has taken a different approach to data center design. Instead of just adding more horsepower in the way of cooling we've attacked the problem head-on. Rather than focusing on the cold air, we capture the hot air before it contaminates the data center environment which results in a dramatic increase in operational efficiency. By capturing the hot air we no longer contaminate the environment. This means we no longer have to provide air colder than necessary to compensate for the mixing. Hot spots are eliminated which eliminates the need for high velocity cooling which prevents terrible working conditions in the way of wind noise and fatigue. The byproduct of this efficiency is the ability to host incredible density per cabinet- in our facilities we can provide up to 20 kW per cabinet with potential for even higher loads. Having an incredibly dense environment with high power caps means that you can fully utilize your cabinets today. It also means that you can continue to upgrade your environment well into the future; from 20 2u servers to 40 1u servers replaced with 4 blade chassis, fully utilizing your cabinets without expanding your footprint. A more static footprint always is more manageable and less expensive to operate.
