What Is a Server Motherboard?

It is called the mainboard, systemboard and motherboard; it is installed in the chassis and is one of the basic and most important parts of the server.

Server motherboard

Called the mainboard,

The requirements of ordinary home PC motherboards are more on performance and functions, while server motherboards are motherboards specially developed to meet server applications (high stability, high performance, and high compatibility). Due to the high operating time, high operating intensity of the server, and the huge amount of data conversion and power consumption,

The first server motherboard generally supports at least two processors-different chipsets (often dual-socket servers, single-socket servers sometimes use desktop motherboards).

Almost any part of the second server supports ECC, memory, processor, chipset (but high-end desktop computers also begin to support ECC)

The third server has redundancy in many places. Even high-end servers have redundancy even with CPU and memory. On mid-range servers, redundancy of hard disks and power supplies is very common. However, low-end servers are often desktop modifications, but Also choose the first-line power plant.

Fourth, because the network load of the server is relatively large, the network card of the server is generally a network card using the TCP / IP offload engine, which has high efficiency, high speed, and small CPU usage, but high-end desktop computers have also started using high-end network cards or even dual network cards.

As for the fifth hard disk, there are already many and more and more servers will use SAS / SCSI instead of SATA.

CPU Server motherboard CPU

Server: Intel Xeon / AMD Opteron & reg; (only for two-socket and above servers)

PC: P4 / Celeron / P4M / Core / Core i3 / Core i5 / Core 7 / AMD

SMP technology:

The full name of SMP is "Symmetrical Multi-Processing", which means that a group of processors are brought together on a computer, and the CPUs share the memory subsystem and bus structure. In this architecture, a computer is no longer composed of a single CPU, but multiple processors run the operating system at the same time, and use memory and other resources together. Although multiple CPUs are used at the same time, for users, they behave like a single machine. The system distributes tasks to multiple CPUs, thereby improving the data processing capacity of the entire system. In a symmetric multiprocessing system, system resources are shared by all CPUs in the system, and workloads can be evenly distributed across all available processors.

Server motherboard memory

Server: ECC / Register

PC: Non ECC

ECC is short for "Error Checking and Correcting", and the Chinese name is "Error Checking and Correcting". ECC is a technology that can implement "error checking and correction". ECC memory is the memory to which this technology is applied. It is generally used on servers and graphics workstations. This will make the entire computer system more secure and stable during work .
