1: CPU purchase

The CPU is derived from x86CPU, one is the CPU of the Atom platform, and this type of CPU mainly includes the Celeron J1900, AtomD525, N2600 and other CPUs. This kind of CPU has no problem in performance, but we take the J1900 as an example to see the features of its technical support.

First of all, even if the theoretical performance of the J1900 is very strong, the J1900 still cannot beat the 1037U of the same period. And you can also see that VT-d is not supported, only VT-x is supported. As far as the CPU used for soft routing is concerned, the performance of the J1900 is no problem. Because pure soft routing basically uses LEDE (openwrt), ikuai, Weimeng and other systems, such systems do not have too many requirements for out-of-order execution architecture, even if the J1900 is fully loaded, it can still bring a gigabit network. That's the horror of x86. So what are the recommendations for buying this type of CPU? If the requirements are not high, J1900 is recommended, and the price is relatively cheap. The D525 is used as the first-generation Atom platform. The technology is relatively old, the power consumption is relatively high, and the performance is poor. It is not recommended to consider it, although its price is really cheap. The N2600 is dual-core and four-thread, and the price is a bit lower than the J1900. If there are not many devices with Gigabit Ethernet, the problem is not big.

For another type of CPU, it is a full-blooded x86CPU. Celeron 1037U is basically used in 1U rack-type soft routing, and does not support VT-D, but if you are rich enough, you can buy i3/i5/ Soft routing for i7, and also supports VT-D. If you have virtualization requirements, you can also consider CPUs above i35005. It is no problem to virtualize a black group or multiple soft routing systems to achieve different purposes. Moreover, the volume of such soft routers is basically not much larger than that of traditional routers, and the power consumption is relatively low. In terms of capacity, even 1037U can handle 300 devices, so there is no need to worry about this.

2: memory

The memory is the foundation to ensure the startup and operation of the soft routing. After all, it needs to run 7x24 hours without interruption. DDR3L is basically necessary, because these types of CPUs come online late, and they are all low-voltage CPU families, and standard 1.5V voltage DDR3 memory may not be available. As for the memory size, if there is no virtualization requirement, 2GB or 4GB can be used. The difference between the two is also small. .

3: Number of network ports

In fact, for soft routers, the number of network ports is not so standard. Two network ports are basically enough for home soft routers. The rest is left to the network switch. Because the biggest difference between soft routing and hard routing is that each network port does not communicate with each other, so it is not just like connecting all the network ports like a normal router. Too many connections will take up your CPU resources. So use soft routing - the connection method of network switches is more suitable, and intranet NAT will not occupy the cpu resources of soft routing.

4: heat dissipation

Heat dissipation is the most important part of soft routing. After all, this directly affects the stability of soft routing. The soft routing is divided into active and passive cooling. The benefit of passive cooling is definitely quiet. And active cooling can keep the soft routing running stably in the weak current box. Passive cooling is perfectly fine for these low-voltage processors. If it is actively cooled, because the fans are generally small fans with high speed, the noise is certain. It is recommended that if it is not to be placed in the weak current box, do not consider the soft routing of active cooling.

The purchase suggestions for soft routing are over here. The system is that radishes and vegetables have their own preferences. Personal suggestions can meet their own needs. Hope it can help you.
