Benefits of Open Compute Infrastructure

Open Compute Infrastructure has a rack scale design level, and this is with good reason. The holistic approach in designing Open Compute hardware has enabled the community to develop a rack that truly is groundbreaking in many ways.

Modular design offers flexibility

The idea behind the highly modular design of an open compute server is that components can be swapped out as computing needs change. Besides reduction in cost (due to less customization), and flexibility in design, modularity offers other benefits such as augmentation (adding new solution by merely plugging in a new module), and exclusion (one of the goals is to move away from the wastage normally associated with a server upgrade).

No tools required for regular maintenance

Open Compute Servers are designed with easy maintenance in mind. Not only is front serviceability providing easy maintenance for the engineer – there are also no tools required for regular maintenance work. Components can therefore easily and quickly be replaced, saving precious engineering resources.

Less components, less weight

The board on a server is a bare bone design, where many common features are removed (as they are not considered needed). Examples of such are monitor ports and multiple expansion slots. Clever workaround designs are made to leave out components without loosing functionality or adding of costs. A power supply? There is no power supply on an OCP server, as it gets powered through a direct interface (from a power bar on the rack). A front bezel on a server usually fits no functional purpose, it actually limits the airflow through the server – therefor you won’t find it on an open compute server design.
All in all, the open compute’s vanity free design takes away on average 6lbs of unnecessary hardware on a server.

Energy-saving fan in Open Compute Servers

The fan law, states that the power used by an electric motor to rotate a pump or fan is proportional to the cube of its rotational speed. In an Open Compute server fans have a bigger dimension (80mm) than a conventional server design (
Fans in the Open Compute server rotate less, therefore consuming very little energy: only 2-4% of total server power, compared to 10-20% for a standard server. By reducing the fan speed with 20%, 50% savings can be achieved on energy consumption.
