Piezoelectric Fans and Comparisons to Traditional Axial Fans
Piezoelectric fans have been a tantalizing subject for research because of the potential of a simple, quiet, efficient option for thermal management in compact applications. Obstacles still remain to their widespread use, such as the requirement for relatively high input voltage and the need for alternating current. The author takes us through flow visualization and experimental testing to provide an insight on their performance and value.
High-Performance Server Cooling
High-performance servers are devices specially designed to handle large computational loads, a huge amount of communication signals, fast data processing, etc. Due to their task oriented nature, high-performance servers must have high reliability, interchangeability, compact size and good serviceability. To achieve high computational speed, high-performance servers generally have dozens of CPUs and memory models. This article explores a high end UNIX server in more detail.
NEBS Standards and Testing Criteria
The NEBS standard was developed by Bell Labs in the 1970s to standardize equipment that would be installed in a central office. The objective was to make it easier for a vendor to design equipment compatible with a typical regional Bell operating company central office, resulting in lower development costs and easing the equipment's introduction into the network. Telcordia now manages the NEBS specifications. This piece examines some of the NEBS thermal criteria in more detail.
Power Issues in Data Centers
Within the electronics industry, we know that there has been a constant evolution towards higher density equipment. But, as with Moore’s law and Rock’s law; with the escalation in capabilities also comes an escalation in cost. This has lead to design concerns at the board and chassis level, as well as growing concerns with the network systems and data centers. This article will look into system design tradeoffs, cooling capabilities, and power consumption; keeping in focus the corporate thrust to minimize the total cost of ownership (TCO).
