Shenhe thermomagnetic: Super fusion dual active cluster solution for MES system

2020 year 5 month , Shanghai Shenhe thermomagnetic Electronics Co., Ltd （ Hereinafter referred to as" “ Shenhe Thermomagnetism ”） In the 25 Anniversary celebration . from 2002 In, it entered the semiconductor silicon chip industry , Shenhe Thermomagnetism in electron , In particular, various specifications of solar energy grade single 、 Polycrystalline silicon ingots and monocrystalline silicon ingots 、 The manufacturing of polycrystalline silicon chips has advanced by leaps and bounds .2019 year , Shenhe Thermomagnetism has composed another “ Veteran xinchuan ”, The large silicon wafer project of Hangzhou Zhongxin wafer semiconductor Co., Ltd. invested and established was officially completed . This is a landmark breakthrough , The first and largest in China 、 Technology is the most mature 、 The semiconductor large silicon wafer production plant with independent core technology and real mass production has set sail .

Stability is everything

as everyone knows , High precision and cutting-edge manufacturing such as silicon wafer is important to material technology 、 Production technology and process , And the product quality has very high requirements . Shenhe Thermomagnetism is mainly introduced by MES System （ manufacturing execution system ） Carry out active management and quality control for each production process , To improve the yield of . therefore ,MES The stable operation of the system has become an important prerequisite and guarantee for the quality of silicon wafer manufacturing .

MES The system starts the overall situation , It must run at high stability 、 Highly reliable IT On top of the infrastructure .

Because of the evolution of history , Shenhe thermomagnetic was the same as most manufacturing enterprises , be based on “ Server virtualization + Centralized storage ” The traditional architecture of , brace MES The operation of the system . The disadvantage of this approach is , There is a clear risk of a single point of failure , And they don't have the ability to recover quickly in a disaster . in addition , With the rapid development of business , The original machine room is in space 、 Refrigeration and other aspects are short of money , It also becomes a potential shutdown risk point , In addition, some servers have a long service life , Insufficient stability and performance .

To protect MES Stable operation of the system ,IT Infrastructure upgrade is imperative . Shenhe thermomagnetic takes advantage of the opportunity of building new computer rooms in different places in the same city , Cooperate with the original machine room , Rebuild the system that can support the key business （ Include MES、ERP Such as system ） Super fusion real-time disaster recovery infrastructure , And in the construction of new computer room infrastructure , Strive to improve resource utilization 、 Save a space , To adapt to the rapid expansion of business . For Shenhe thermomagnetic , The super fusion dual active cluster scheme is “ Kill two birds with one stone ” The choice of .

From the perspective of ensuring reliability and high availability , Shenhe Thermomagnetism was first connected to SmartX, And from 2019 year 7 In June, the company began to conduct in-depth demand discussion and scheme communication . Final , According to the actual needs of Shenhe thermomagnetic Co., Ltd , That is, it needs to be in a park A、B One machine room will be built in the two plant areas , And to achieve real-time disaster recovery , The final decision is based on the popular dual active cluster mode in the industry IT The architecture is transformed .

Equip business development with “ Perpetual motion machine ”

After the environment is ready ,SmartX The professional services team completed the project based on... In only one day SMTX OS Super fusion dual active cluster deployment , And completed the application deployment and related fault drill and verification within one week .

From the whole deployment process , Shen and thermo magnetic are respectively in A、B Two machine rooms in the plant are deployed SmartX Halo Super fusion machine , The two machine rooms are interconnected through bare optical fiber , And pass SMTX OS Constructing cross machine room stretch cluster with super fusion software . With the help of the function of dual active cluster , Realize the complete synchronization of the data of the two computer rooms ,MES The database can be accessed through Oracle RAC The cluster is deployed on two computer rooms , Once any machine room fails , Business systems can be transparently switched to another site to resume operation , Ensured MES High availability of business system .

The core of this scheme ——SMTX OS The dual active cluster consists of two hyperfusion sites and arbitration nodes , The two sites are connected by network , And the physical distance is not greater than 75 km . The business data in the dual active cluster will be automatically synchronized to the remote site in real time , In case of fire or power failure, etc , Business can be quickly migrated to available sites , And resume operation in time .SMTX OS Dual active cluster ensures IT High availability at the infrastructure level , At the same time, it shall cooperate with the real-time application cluster Oracle RAC, Achieve high availability at the business level ,“ both ” Fully meet the application requirements of Shenhe Thermomagnetism .

To ensure the high availability of the whole system , Shenhe thermomagnetic specially conducted a fault drill , Results show ,MES Systematic RPO by 0,RTO Close to the 0, The expected disaster recovery effect has been achieved . More Than This , Built on the super fusion dual active cluster MES The running speed of the system is doubled , The purchase cost has been reduced 30%. meanwhile ,ERP、OA And other important production business systems can also be accessed through V2V Patterns are migrated to a hyperfusion environment , Easily complete the upgrading of hardware equipment .

Witnessed and personally participated in the whole IT Shenjianfeng, head of the thermal and magnetic information management department of the Shenhe, who is engaged in the structural transformation, is deeply impressed ：“SmartX Super fusion dual active cluster solution , For our MES The system provides highly reliable support , It effectively ensures that production does not stop .”

Super convergence has become the mainstay of key businesses

In recent years , With the development of domestic chips 、 The vigorous development of semiconductor industry , The business growth of Shenhe thermomagnetic has accelerated significantly , The layout is getting deeper and deeper . But as it stands , Semiconductor silicon wafer is still one of the links with the largest gap between China's semiconductor industry chain and the international advanced level . Shenhe thermomagnetic will continue to tap its potential , Achieve leapfrog growth .

Twenty five years of hard work , Shenhe thermomagnetic has never stopped advancing in the high-end manufacturing of silicon wafers , The unremitting pursuit of technology and quality is the driving force for Shenhe thermomagnetic to move forward . And as a booster ,IT Infrastructure should also keep pace with the times , For stability 、 Efficient 、 High quality production and manufacturing escort .SmartX It has unique products and solutions in the field of super fusion , In particular, the dual active cluster solution based on hyper convergence is very suitable for enterprises that have strict requirements for stability and availability .

More and more successful practices show that , The super fusion architecture is fully capable of carrying the key core businesses of the enterprise , Become a stable development and innovation of business “ anchored ”.
