To date, the data center industry has had to become innovative as they seek to respond to the increasing demand for power. As part of their innovation best practices, forward thinking data center managers have turned to high-density and high-power rack PDUs with sensors. This technology is designed to help data centers become "green," reduce their carbon footprint, and effectively respond to the ever-increasing demand for power and density of IT equipment at the rack level. 

ASHRAE: Best Practices for Environmental Monitoring of Humidity and Temperature

Data centers now consume an estimated 1.8 percent of electricity within the United States. As energy consumption has risen, so too have the associated costs. These costs, coupled with the fact that approximately 30 percent of data center servers are either idle or underutilized, have resulted in unnecessary expenses that could have been mitigated with the right environmental monitoring best practices. These best practices include monitoring temperature and humidity in accordance with ASHRAE 90.4. 

What Is ASHRAE 90.4 ? 

In its simplest forms ASHRAE 90.4 is a new standard that is designed to help data centers effectively monitor temperature and humidity levels so that downtime is reduced, and enhanced efficiencies can be introduced. This standard focuses on the use of on-site and off-site renewable energy. It uses both Mechanical Load (MLC) and Electrical Loss (ELC) to better determine the maximum allowable values for climate zones. At its core, ASHRAE 90.4 helps data center managers understand when they are undercooling their machines and operating at detrimental humidity levels, so that power utilization can be enhanced for the entire data center. 

Idle Server; What Does This Mean For Your Data Center?

In theory, a data center should be a well-orchestrated entity where a certain technological harmony is achieved. Unfortunately, much like a seven-year-old learning to play Frère Jacques on their new recorder, data centers can easily become a disconcerted mess of idle servers. According to a recent survey by the Uptime Institute, approximately 30 percent of global data center servers are either underutilized or completely idle. To move beyond Frère Jacques to a beautiful symphony, data center managers must first identify why idle servers exist.

Power Capacity Planning With Intelligent PDUs

In recent years, energy costs have more than doubled for some data centers. As energy costs have risen, so to have the demands for power increased. The combination of rising energy costs and power consumption needs has led to new demands for more efficient power capacity planning. In fact, power capacity planning just might be one of the most important tasks that data center managers will tackle this year. 

The Advantages Of High Power PDUs

A Power Distribution Unit (PDU) at its most basic level is a device that is fitted with multiple outlets. However, an intelligent and high power PDU is far more effective than a basic PDU. In fact, a high power PDU is not only capable of providing specific levels of electric power to storage devices, servers, and networking equipment, but it can deliver effective and long-lasting advantages to data centers throughout the world.
