1.What is an AI server？
The three elements of deep learning are data, algorithms, and computing power. Among them, data is the foundation, algorithms are tools, and computing power is the booster. The increase in computing power drives the development of deep learning. Deep learning has developed slowly before, except for algorithms. In addition to the reasons, a very important reason is the lack of computing power. The most important support for solving computing power is the AI server. From the perspective of the hardware architecture of the server, the AI server is a heterogeneous server. In the heterogeneous mode, different combinations can be used according to the scope of the application, such as CPU+GPU, CPU+TPU, CPU+other accelerator cards, etc. Compared with ordinary servers, there is no difference in memory, storage, and network. The main aspects are big data, cloud computing, artificial intelligence, etc., which require larger internal and external storage to meet the collection and sorting of various data. Ordinary GPU servers are generally single-card or dual-card. AI servers need to undertake a lot of calculations. Generally, more than four GPU cards are configured, and AI server clusters are even to be built.
