WenAi Cloud: A simple evaluation of Hong Kong Mega Two data center three-network cn2 gia line

wenaiyun, registered in Hong Kong (LOKWIN INTERNATIONAL LIMITED) in 2020, mainly operates cloud services for Hong Kong (cn2 gia, cn2 gt), Japan CN2, and the United States (cn2 gia, cn2 gia high defense, AS4837) lines Server, independent server, site group server, CDN and other services.

This article will conduct a simple evaluation of the Hong Kong Mega Two computer room and the three-network cn2 gia return cloud server, and share some data for your reference!

Supports Windows and Linux systems, the system disk and data disk are separated, and comes with an IPv4

Memory	CPU	Hard disk	Traffic	Bandwidth	Price
1G	1 core	40G	300G/month	10M	29 yuan/month
2G	2 cores	50G	500G/month	10M	50 yuan/month
4G	2 cores	60G	800G/month	10M	80 yuan/month
4G	4 cores	70G	1T/month	15M	120 yuan/month
8G	8 cores	100G	2T/month	20M	220 yuan/month
16G	16 cores	140G	2T/month	20M	400 yuan/month

I got a low-end version with 2G memory and 2 cores for a simple evaluation. I turned on BBR to see if it was useful or not. The hard disk I/O was about 190MB/S:

The details of FIO test hard disk read and write data are as follows:

No matter how good the network is or how large the bandwidth is, we cannot guarantee it without testing it in mainland China. We used speedtest.net to test the effect of this test chicken on the three network nodes in mainland China. The data in broad daylight is as follows:

Looking at the evening peak period, there is almost no attenuation:

Testing of other nodes in Asia:

The following is the data of Europe and the United States when iperf3 is running:

File stored on the test machine, Chrome download, Guangzhou Telecom, effect in broad daylight:

Effect during evening peak backbone network explosion (no attenuation):

The delay detection of 80 nodes in mainland China is very beautiful:

Outbound telecom, CN2:

China Unicom outbound: direct backbone connection, using Bgp.net

Move outbound, go directly to the computer room after CMI:

Return to Mainland China Telecom:

Towards Beijing, take CN2 and come back;

In the direction of Shanghai and Guangzhou, AS4837 is used to connect to the Hong Kong node and return. I think we should remind the official to adjust it here. Although it is not bad, it would be better if it can use CN2.

Return to China Unicom: Directly return via AS4837 from the relevant node of China Unicom

Return to China Mobile: Return directly from China Mobile’s node in Hong Kong

Streaming media test, roughly as follows, for reference only:

Unix bench Mark：

To summarize:

For the outbound journey, China Telecom takes CN2; China Unicom and China Mobile are directly connected;

For the return trip, Beijing Telecom currently uses CN2, Shanghai and Guangzhou Telecom use China Unicom AS4837 to return directly; China Unicom all Hong Kong nodes AS4837 return directly, and China Mobile also directly connects back.

There is no problem with the network at all, everything is directly connected; the speed will not be bad, but it will be better if you switch to Telecom CN2 GIA. Officials here need to pay attention to their own routing, don't let bgp.net switch mess up!

The bandwidth of 10M and 20M is more than enough for making websites and so on. There is no problem with the speed. It also supports Windows and can be used for remote office work.
