At present, it is difficult for the data center to cope with the pressure of massive data. The development of next-generation data centers has become an imminent task. What kind of standardization can meet our data needs?
Heterogeneous Networks in traditional data centers
After years of development and transformation, data centers have become the heart of enterprise IT systems. However, with the development of enterprise informatization and the explosive growth of information, data centers are facing unprecedented challenges. The complex and heterogeneous networks accumulated during the continuous construction and upgrade of traditional data centers impede the development of data centers in an efficient and agile manner.
From the network structure of the Data center, there are three relatively independent networks: Data Network Data), Storage Network SAN) and high performance computing network HPC. The basic status is as follows:
• Front-end access interfaces of data centers are usually interconnected over Ethernet, forming a high-speed data network
• The back-end storage of the data center uses NAS and fc san.
• The parallel computing of servers mostly uses Infiniband and Ethernet.
• Different servers have heterogeneous operating systems and upper-layer software, and different interfaces and data formats.

Unified Exchange architecture of Standardization
To facilitate future business integration and service provision, simplify management, reduce construction costs and operation and maintenance costs, and solve various problems arising from the heterogeneous network of traditional data centers, the construction of data centers should avoid the existence of heterogeneous systems as much as possible. A unified standard should be used to plan a complete data center network system.
Standardized unified architecture
In business networks, Ethernet has continued to develop along with technological changes to meet changing industry and market demands. Since the widespread adoption of Ethernet in 1983, Ethernet NICs were adopted by most PCs in 1995, then to Fast Ethernet (100 Mbps) and Gigabit Ethernet (1000 Mbps) and today's 10-Gigabit Ethernet and the upcoming 40 Gbps and 100 Gbps Ethernet standards. Ethernet has undergone a revolution from terminal to Lan, from LAN to Wan, and from Wan to man. It can be said that Ethernet is growing and expanding with its powerful vitality.
In the storage field, IP Storage has developed rapidly since its birth, and 10-gb storage has brought storage into a new era.
In the fields of supercomputing and high-performance computing, the world's top 285 supercomputer rankings published in 57% show that sites use Ethernet connections, accounting for of the shares.
With CEEConvergence Enhanced Ethernet converged Enhanced Ethernet) to improve the existing Ethernet standard, Ethernet solves all technical problems faced by data center applications. Converged enhanced Ethernet has become the best choice for building a unified switching architecture data center.
Enhanced Ethernet
The birth of the CEE standard changed the Ethernet from the "Best effort for Best-effort" transmission mode to the "Lossless network Lossless)" transmission mode that is more suitable for the data center environment. H3C's new-generation data center solution network infrastructure is based on the "Unified Exchange architecture, the computing, storage, and data networks in traditional data centers are unified to a high-performance data exchange platform based on 100 Gbps Ethernet, making full use of high-density 10-Gigabit Ethernet and converged enhanced Ethernet, the synchronization of large traffic, large backup traffic, and large volume of Virtual Machine migration within the data center eliminate the bottleneck in the data center, meeting the needs of the next-generation data center for efficient business.
Heterogeneous multi-layer and unified exchange architecture
H3C is a new-generation data center based on the Unified Exchange architecture. It not only solves the technical difficulties of data, computing, and storage separation through integrated means, but also can use 10g technology, it helps users Reduce data center cabling by 60%, greatly reducing procurement and resizing costs for data centers. The entire network adopts simple and practical Ethernet technology, this simplifies the network layer, eliminates network performance bottlenecks, increases the flexibility of business deployment, and simplifies the network maintenance workload.
