Effective data center Energy saving can save 40% or more energy expenditure. Imagine a data center that consumes 10 times to 100 times times as much energy per square foot as an office building, and in some cases the highest energy consumption, or even 40% of the company's greenhouse gas emissions, is clear about how important it is for the data center to conserve power and reduce consumption. Data center executives often do not have comprehensive management tools to monitor energy consumption. Therefore, the lack of the energy strategy of the system analysis to determine the data center energy-saving can bring great benefits is what or high-energy consumption will bring great risks to the operation of the enterprise. ...

Data center air-conditioning systems generally do not fail in the depths of winter-Murphy's law once again proves that such failures often occur in hot summers. No matter when the cooling system is interrupted, the data center will experience a warming up process that may threaten the server and other devices. You are walking on a crisis path if the cooling capacity is critical enough to shut down one of the single room Air conditioning units (CRAC) for maintenance. This chapter describes some of the best practices for maintaining CRAC. Before we go into this article, please note that all types of room air conditioners are called Crac, but from the dedicated ...

A few weeks ago, when William Lansing, chief executive of FICO, attended Stanford University's Big Data conference, he found that the industry's heated discussion of big data had increased from three "V" to four "V", that is, volume (data volume), produced (data type) , velocity (processing speed), and value (data values). and the fourth "V" means that the industry is starting to focus on data insights, emphasizing how to get the value of large data.

Although interoperability experiments and demonstrations involve alternative data Center architecture standards, proponents of non-standard architecture technology say non-standard technologies are superior. Multi-chassis Link aggregation (mlag) and two penetration architecture standards (trill and shortest path bridging SPB) are designed to create multiple valid paths to address spanning tree limitations, reduce latency, and facilitate "East-west" flow between server racks. These three technologies are designed to extend or replace the spanning tree,spanning tree of the data center Ethernet to allow a ...
