Shuguang recently announced the revolutionary infrastructure liquid server TC4600-LP. It is introduced TC2600-LP products for the dawn of the newly developed indirect hybrid cooling liquid-cooled server, which has low PUE value, higher density, higher reliability, energy saving and low cost advantages.

TC4600-LP is the dawn of the mainstream http://www.aliyun.com/zixun/aggregation/13737.html "> Liquid cooled version of the blade server TC4600, its main performance is exactly the same with the air-cooled version, but TC4600-LP due to CPU core temperature is reduced, the fan is reduced, the server power consumption is reduced by 5%; In addition, due to the infrastructure of the GreenLC overall program has a year-round natural cooling function, the infrastructure cooling system to reduce operating energy consumption 40-60 %.

Innovation tradition, breaking the cooling bottleneck

As the data center power density continues to increase, the traditional server air cooling mode brings three problems brought about by the air-cooled cooling system gradually highlighted: First, local hot spots tend to appear during operation; Second, high operation energy consumption and poor PUE indicators; Third, In the long run, further improvements in power density are limited.

The disadvantage of the traditional cooling method is that the cooling system consumes high energy. There are two main reasons for this: Compared with liquid refrigerant, the air has large power and large heat transfer temperature, which is a bottleneck that hinders the increase of power density. The former results in a large power consumption of the fan, the latter resulting in having to use compressor refrigeration while the compressor consumes much more power than a naturally cooled pump system. For example, data centers using air-cooled servers-room air conditioners may not have a PUE of less than 1.4 without UPS systems, and liquid-cooled servers-naturally cooled cold data centers with PUEs easily reduced to Below 1.2, it can even reach 1.1.

Understand the dawn of data center server energy saving From 2012 onwards in the field of energy-saving innovative technologies, since the start of liquid-cooled server R & D projects, after two years of efforts, Dawn formed server liquid cooling technology and supporting infrastructure technology platform, and at 3721.html "> In August 2014, the first mass-produced TC4600-LP indirect mixed-flow liquid-cooled server was introduced.


Dawning TC4600-LP liquid-cooled server

Shen Weidong, General Manager of Dawning Data Center Products Division, introduced a liquid-cooled approach to reduce thermal resistance during energy transfer and reduce the heat transfer temperature difference, allowing for natural cooling at outdoor temperatures of up to 30 ° C and no compression required Cold mechanism. Significantly reduce the PUE, under ideal circumstances can be reduced to PUE 1.2 or below, and even exceeded the 1.1 mark.

The data show that the traditional blade server fan power consumption of the blade server can consume 8-10% of the total power, and Shuguang TC4600-LP indirect hybrid-cooled liquid-cooled server pump power consumption accounted for only 1-3%, saving 60 %, While running noise can be easily controlled below 45dB.

Seek the ultimate, dawn to open the perfect liquid cooling product portfolio

The Dawning Company, which has always been devoted to exploring the research of efficient refrigeration technology, designed the TC4600-LP to take the cool thinking of the server cooling technology by designing the TC4600-LP to effectively cool the server's heat using a combination of liquid cooling and air cooling.

The so-called indirect cooling, that is, the cooling medium and the heating element are separated by the heat conducting material, and are not in direct contact with each other. Instead, the heat of the object to be cooled is transmitted to the cooling medium through the efficient heat conduction components such as the liquid cooling plate and the liquid cooling head.

The indirect cooling of the liquid cooling system, the original computer system does not change much, just the original air-cooled heat sink replaced by liquid-cooled heat sink (liquid cooling head), and the refrigerant line leads to the chassis; indirect Cooling method, the refrigerant has its own access, not in direct contact with the electronic devices, so the liquid pipeline requires good sealing, refrigerant does not leak, the system less demanding on the refrigerant, a variety of refrigerant can achieve its function.

In terms of operating expenses OpEx, TC4600-LP with CloudBASE GreenLC infrastructure overall program, for a 500kW medium-sized data center can save 1.5 million yuan per year of electricity costs. In the meantime, due to the increased power density, the data center can reduce the area of ​​the machine room by 20% or increase the utilization of the computer room by 20%. In addition, for northeastern and northwestern China, it is also possible to heat the building by using waste heat in winter, further reducing OpEx, the operating cost of the entire data center.

In terms of equipment investment in CapEx, the cost of the cooling system infrastructure declined compared to the air-cooled version of the TC4600, although the cost of the liquid cooled version of the TC4600 increased somewhat, so the CapEx for the entire data center remained virtually unchanged.


TC4600-LP system diagram

In the overall TC4600-LP system design, a CRU (cooling cabinet) + 2 cabinet server rack (12 boxes, 120 pieces) form a minimum cooling unit. Liquid-cooled and air-cooled two systems combine to provide cooling solutions for servers. They are integrated in cabinets to form CRU cabinets. CDM modules and CIM modules exist in the cabinets at the same time.

According to reports, each box TC4600-LP design heat 4kW, of which liquid cooling system to solve 2.7kW, air-cooled system to solve 1.3kW; single CDM cooling capacity of 10.8kW, is responsible for the two cabinets inside the four HCDU with cooling, There are 3 CDM modules in the CRU cabinet to solve the problem of cooling with 12 knife boxes.

Since about 70% of the server's heat is taken away by the liquid-cooled system, the capacity of the air-cooled system is only about one-third of the original capacity, and the Dawn CloudBASE C1000, C2000, C3000 or C4000 series solutions can be easily solved to achieve TC4600-LP's overall cooling problem.

Researcher Zhang Guangming, an expert in data center energy conservation and executive deputy director of China Data Center Energy Saving Technology Branch, said that server liquid-cooling technology is bound to bring about changes in the physical form of servers and bring about changes in the construction mode of data centers so as to create a pattern for the informatization industry Revolutionary influence From the debut of the ISC'14 Dawning Immersion liquid-cooled server PHPC300 to the introduction of the TC4600-LP, an indirect hybrid-cooled liquid-cooled server that is now in full production in the dawn, energy-saving and consumption reduction have brought about revolutionary innovations to enable the data center as a whole Improve cooling energy efficiency.
