Stable Server Operations Begin with Innovative Design Technology

Extensive airflow analysis and heat-exhaust design

Servers operate 24 hours a day, 365 days a year. These conditions demand sufficient cooling capabilities to help to extend the life of the hard disk, parts on the motherboard, and other components.
When designing the Express server series, ensuring airflow was given top priority, and extensive cooling tests were conducted for each model.
NEC understands that, without a sufficient cooling system in place, servers densely mounted in rack cabinets—especially racks loaded to capacity—are particularly prone to overheating. Experimental models were created after conducting numerous cooling tests of more than 10 hours each. These tests helped determine the best arrangement of components within the server. Following this, using our proprietary peak load-generating tool, NEC measured temperature distribution while the machines were producing their maximum amount of heat. This careful planning led to the conclusion that a rack server can be installed with peace-of-mind even in a full 44U cabinet.

Intensive heat simulations helped create a structural design which takes cooling into account

NEC knows that our customers demand security. With that in mind, NEC designed our Express servers with standard key lock-compatible front bezels.

Air slits

Unobtrusive air slits have also been included in the front cover design. These easily increase the air flow necessary for top performance.
