The SH1206 review has a total of 4 electrical ports supporting 2.5G rates and 2 fiber ports supporting 10G rates, and the switch chips are BCM54994EB0KFSBG and BCM53161XUB1, Broadcom solutions, unmanaged switches.
I asked if there were any other 2.5G electrical port switches cheaper than it, someone replied I have Wistron QSW-1105-5T, about $ 100. QSW-1105-5T only five 2.5G electrical ports, no 10G optical port, so it lost the wide range of accessible devices and scalability. As shown below, the Intel X520 single-port network card in the picture below is bad, inserted into all computers are not any gross response, just lying here for me to take pictures, no other use. The yellow network cable is connected to the most 2.5G network card, the chip is RTL8125B, $15 or so a, not expensive.
Scalability includes the ability to connect another switch and have a 10 Gigabit fiber port available after the connection.
Then, you can also use this way, some WIFI6 router with 2.5G LAN port, computer or NAS connected to the 10 Gigabit fiber port of the switch, another computer plug RTL8125B or use USB3.0 to 2.5G network port connected to the switch. USB to network port is about the same price, I also bought one to play, speed measurement and PCIE interface the same.
If the home area space is large, one can not cover, and then add an additional XDR6060 it. For example, this is how to set up a network.
If you do not have a good layout of the network cable, and want to achieve the speed of the gigabit network cable network, you can also pull the invisible fiber, for example:
The ASUS AX86U can also be connected to this switch, but I don’t have two AX86Us and I don’t know if its 2.5G port can be networked.
Because there is no fiber optic network card, I can only use a network card to connect to the network interface of the Netgear XS508M, and then through its fiber optic port to the optical port of this SH1206, which can only measure one of its optical port. This is not the way, so later or to buy a used fiber optic network card.
Test a variety of network cards, realtek 2.5G network card there are three, Intel X550, and an AQC107.
First look at the power situation.
Power on, what port is not plugged, power 4.2W, only plug a 2.5G port power 5W, after the first increase of a network port about 1W, and finally connected to a fiber optic port after the power 8.3W, if you plug a second fiber optic port, it is estimated to increase 0.3W only. 12V / 1.5A power supply is sufficient. No matter how many ports are transmitting at high speed, the switch power will not increase. Unlike a wireless router, the power will increase significantly when transmitting wirelessly.
The next step is to test the network port throughput rate, using IxChariot software, scripted with Ultra_High_Performance_Throughput, ten threads, time 1 minute. All NICs are not enabled for jumbo frames.
The corresponding rates of the SH1206 switch’s network ports are as follows, 1 to 4 are 2.5G ports, 5-6 are 10G ports, and I only connected one of the 10G ports on port 5.
First test the four 2.5G network ports, the results of the following table.
LAN1 to LAN2: 2384Mbps, 4708Mbps in both directions
LAN1 to LAN2 and LAN3 to LAN4 transmit at the same time, 4744Mbps in one direction, 8749Mbps in both directions.
The total traffic of the four 2.5G ports is 8749Mbps, which is twice the measured backplane bandwidth of these four ports: 17Gbps. This is the measured data of aciwfi, and the results vary with different settings of different NICs.
Then test the throughput rate between these 2.5G network ports and another 10G network port. Test out the bus connection speed between the two Broadcom switch chips. The results are shown in the following table.
The above table is divided into three columns to see, it will be more regular.
The first column, 2.5G port sends to 10G port, no matter how many 2.5G ports transmit at the same time, no attenuation, when four 2.5G ports transmit at the same time reached the bottleneck of 10G network port 9478Mbps. the result of this column is no problem, it is normal.
The second column, 10G port transmits to 2.5G port, when the number of network ports is more, the attenuation is bigger, when there is only one port, the speed is normal, when sending data to 4 2.5G ports at the same time the total throughput rate is only 5005Mbps.
The third column, two-way transmission, because there is a direction much slower, will certainly affect the two-way performance, when the four ports work together, the two-way only increased 2000Mbps.
Finally I tried to turn on all NICs with 9K jumbo frames, same result. Changing to another NIC also did the same, and the two NICs could run up to 18500Mbps in both directions.
The 2 10G optical ports can’t be measured, so I’ll make up for it after I buy a new NIC.
SH1206 four electrical ports total bandwidth no problem, between the electrical port and 10G optical port some problems.
From my amateur test results can be seen in.
4 2.5G network ports are completely fine.
no problem at all when sending data from four 2.5G network ports to 10G ports either.
When using 10G port to send data to multiple 2.5G ports there is a problem, the speed drops. I can’t find the reason yet, so if you know anything, please leave a message to tell me. Thanks!
The price of 100$ is acceptable, if you want to search for yourself, just pick the low price.
