Description

Server system

The present invention relates to the technical field of servers, and more particularly to a server system.

The current development direction of the server is to separate the calculation and storage and then connect the calculation part and the storage part through a high-speed transmission line. The advantage of separation of calculation and storage is that the same hardware resources are grouped together for easy maintenance and replacement.

In general, the technology for separate storage is to use a dedicated storage master chip via SAS/SATA, or PCIE to SAS/SATA to connect to a mechanical hard drive or solid state drive. Then, the dedicated storage master chip is connected to the Ethernet card chip through the PCIE, converts the stored data into an SFP+ module optical signal, and transmits the data to the SFP+ module of the dedicated computing server through the optical fiber. Then, the SFP+ module of the dedicated computing server converts the received storage data into PCIE through the Ethernet network card, and then transmits it to the CPU of the computing server to calculate and process the stored data.

However, the data stream access and transmission of the entire stored data requires a lot of complicated signal conversion processes, and the delay of the data stream and the performance overhead are quite large, so that the efficiency of the calculation and storage separation is very low. Therefore, there is still room for improvement in the design of the server.
