  • The Technical Path of 5G Needs to Be Clarified Urgently

    5G has defined three use cases, and each requires a technology phase not less than 5 years. Assuming the deployment of 5G begins in 2019, it might take more than 10 years to achieve the 5G network in our imagination. We have to analyze the feasibility of technology and application, so as to provide a basis for the rethinking of superstructure. The Three Use Cases of 5G The first use case of 5G is eMBB, short for Enhanced Mobile Broadband. It is defined to achieve Virtual Reality (VR) technology and Ultra-High Definition (UHD) video sharing, cloud access anywhere and up to 1Gbps of Internet bandwidth. The second use case of 5G is uRLLC, short for Ultra Reliable Low Latency Communications. It includes low latency automatic driving and industrial Internet etc. The last use case of 5G is mMTC, short for Massive Machine Type Communication). It is defined to realize vehicle networking and intelligent asset management, that is, to make Internet of Everything (IoE) become a reality. The three use cases of 5G have covered every technology field that human technology…

  • Data Center Design: Cost, Technology, Conciseness and Reconfigurability

    100G data centers are maturing, no matter from which angle, the technologies are getting more and more perfect. The 100G data centers can already carry most of the things we want, but at most it only loads the memory and spiritual food of human life—we do see some computations, but such computations are no different from the supercomputing of the previous era. If we don’t understand the goal of data center applications, we can’t design a data center that matches technologies and applications. Optical interconnection technology is moving from 100G to 200G and 400G. Perhaps we can say that 100G optical interconnection has just reached its robust performance in 2018. So we can basically assert that the 100G data centers built before 2018 are all dangerous buildings or houses built on sandy land. We must be aware of the risks. The current large data centers basically follow the 100G CWDM4 structure of the last era, and use AOC and DAC the same time. Today, we need to retell a topic. The proposal is to divide the data center into two…

  • QSFP-DD Might Be the Mainstream Form-factor of 400G Optical Transceivers

    Time to enter 2019, when 400G has become a hot topic in the optical communications industry, the world’s leading optical transceiver manufacturers have launched their own 400G optical modules. When we list the form-factors of these manufacturers’ 400G optical modules (as shown in the figure below), we found that all the manufacturers except the Finisar (acquired by II-VI) have adopted the QSFP-DD form-factor — the market seems to have recognized QSFP-DD as the first choice for form-factors of 400G optical modules, though some manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors. 400G Form-factors of Mainstream Optical Transceivers Manufacturers Tips: QSFP-DD is a high-speed pluggable module form-factor defined by the QSFP-DD MSA group. The QSFP-DD MSA group has defined the next generation, high-density, high-speed pluggable module form factor that addresses the industry need for high-density, high-speed networking solutions in a backward compatible form factor. The QSFP-DD Specification has been developed and refined by many companies within the QSFP-DD MSA group and released to the public. Why do mainstream manufacturers choose the QSFP-DD form-factor? Does this mean that the…

  • Data Storage Security in Cloud Data Center

    With the development of cloud computing, cloud data centers are used more and more widely. More and more enterprises choose to use cloud data storage services. In this way, they need not buy expensive equipment or hire specialized personnel to manage data responsibilities. At present, the data storage security in cloud data center has become the first condition for enterprises to choose their own cloud platform (cloud data center). So, how to define data storage security? We can consider these aspects: data stability, high availability, data access security and data durable availability. Data Stability The data storage service provided by cloud data center should ensure the stability of each tenant’s access. It will not affect the normal business access of other tenants because of the sudden large number of I/O access to storage by individual tenants. In the design of SAN network architecture, the overload ratio between host and storage is considered to avoid congestion or performance degradation. At the same time, the core-edge SAN network design architecture is adopted to achieve flexible expansion. The response time and processing capacity…
