The Five-Star Red Flag Flutters in the Wind!
The first picture pays tribute to our great motherland. When I was young, I didn’t feel much when singing the song “Singing the Motherland”, but with the increasing strength of our country, compared to the wars abroad, I truly feel that being born in the People’s Republic of China is an incredibly proud thing. So as young people in China, we should work hard to improve ourselves and contribute our meager strength for the world and the future development of China.
Once again, it is the National Day holiday for 7 days. As a local Beijinger, I will inevitably be at home making space for friends visiting Beijing. I once tried to travel during the National Day holiday, thinking I was very smart and tried to avoid peak travel times, but on the road, I found that the highways were full of people with the same idea as me, stuck in traffic together, the cars sputtering and burning fuel, the fuel consumption skyrocketing. In the end, it was better to stay at home and play on the computer. After all, everything can be solved with a few kilowatts of electricity, why spend a lot of money to go out and see people? After all, everything is in the computer, and recently we set up a Raspberry Pi server. I believe everyone has already stored up the resources they want to watch during the National Day holiday.
Today was originally a boring day, but I received a private message from a senior in the public account. Many people have the same feelings as this senior recently. For some reason, my two articles about Raspberry Pi have attracted a lot of attention and reading from netizens. First of all, I would like to thank everyone for taking the time to read these boring articles despite their busy schedules. Although we are in an era of information explosion, many people have gradually started to acquire more knowledge through short videos, but the transmission of text may be a more effective way of passing on civilization. Secondly, regarding the previous two articles about Raspberry Pi, I just wanted to use technical means to make my Raspberry Pi, which has been gathering dust at home, come back to life. I thought about why I bought the Raspberry Pi in the first place, why I bought it? And why did it gather dust? These are very contradictory questions. And why did I switch from the Raspberry Pi to a regular computer? This is an even more contradictory question. This article does not contain any practical or particularly technical content; it mainly discusses the facts and significance of our energy consumption.
#Electric Meter Becomes Fan Artifact#
As we all know, the electric meter is a device used to record our electricity consumption, and it is an essential household appliance in every family. In normal measurement units, 1 kilowatt-hour equals 1 degree of electricity, which is basic knowledge from junior high school physics. If we use a 1000W induction cooker at full power for one hour to eat hot pot with friends, then theoretically, we consume 1 degree of electricity, and according to your local billing standards, possibly a plate of steamed buns or a serving of lamb will be gone; this is the premise.
Next, let’s talk about the devices around us. I will take my own service computers that can read actual data as examples; this only represents myself but can explain everything.
– Home Storage: Dell R730Xeon(R) CPU E5-2620 v3/64GB/10x2T SAS(raid5)/8x1000Mbps(LACP) Yes, you read that right, this is a computer, a standard rack server. It does not have an outstanding appearance, but it has relatively stable performance. In fact, this configuration is quite average among conventional servers, but for my personal use at home, it is more than enough. It solves all my file storage problems at home. My movies, work files, game installation files, and phone backups are all supported by its smb, ftp, and other services. At the same time, devices like TVs and TV boxes at home can also use it to play videos. Although major operators have launched FTTH fiber-optic services, it is currently only available at your home; many devices on the internal network still maintain hundred megabit or gigabit internal network speeds. Therefore, when I initially selected this server, I made sure to add a 4-port gigabit network card. This way, using ESXi’s link aggregation software and a Cisco switch, I successfully set up LACP, ensuring that when the TV watches high-definition movies through this server, I can also connect to this server and upload movies, transferring the bottleneck to storage itself (an old enterprise-grade 2T SAS hard drive is expensive). To solve the power outage problem, I also set up two 900W power supplies, one for the mains and one connected to a small UPS. Later, the UPS broke down, and the power supply was left unused… Others: “You have a bit of a problem,” except for the local Unicom technician in our area saying I am impressive, this is probably the most frequent comment I’ve heard. Back in high school, because of a broken desktop hard drive, I had a period of memory that was blank, like an unverified record. Of course, I admit that I have gone a bit deep down this road, but for someone like me who values data, this is nothing.Now, let’s talk about power consumption. The motherboard, a few inconspicuous small fans, 10 hard drives, and cards now average: 246W/h, per day: 246*24/1000=5.904 degrees, several steamed buns are gone in a day. According to the logs, since 2015, the system has accumulated a count of 10155kwh, a computer that could defeat the black Wukong is gone, a powerful graphics card is gone, half of a Wuling Hongguang is gone, but what remains is data~~When I was not working back then, if my mom knew this data, I would definitely get beaten. Fortunately, I am now paying the electricity bill, haha! Burp~ Wuling Hongguang
Curious netizens: How did you count it? As shown in the picture, this is a built-in module of the Dell server called iDRAC, which is convenient for maintenance personnel to manage the server. It is like a small computer built into the server, similar to a Raspberry Pi, with its own independent system and independent network interface. By accessing the management page of this module, you can remotely control the server’s power on and off, read or set all configuration parameters of the server, and even remotely control the operating system installed inside the server through this webpage. It is very powerful, and you can search for more information online. Additionally, the Raspberry Pi can also be used as a similar iDRAC card in your desktop computer with some DIY modifications, giving the Raspberry Pi a new purpose~~ – Application Server: Dell T640
Xeon(R) CPU Gold 6248/128GB/3x2T SAS(raid5)/2×2.5Gbps This is a tower server that resembles a home computer case; it is an application server and one of the business server nodes for a biscuit company, running some scattered business data. There is not much to say; perhaps the business allocation is small, so the hard disk is also small, resulting in less power consumption, and it runs less. The iDRAC display shows an average of 135W/h, per day 135*24/1000=3.24 degrees, again several steamed buns are gone~~
– Gateway Server: Assembled Mini Server
Xeon(R) CPU E5-2650L/32GB/1000Mbps x3/25Gbps x2 A mini server, similar to the current x99 motherboard, measuring 17cm x 17cm, mainly responsible for Softether, DHCP, and DNS services, the next successor to my home optical modem. From the onboard interface, it is clear that this is a computer that cannot play games; knowledgeable players should be able to recognize the motherboard manufacturer at a glance. The biggest advantage of this motherboard is that it also has remote management capabilities, although not as powerful as iDRAC, but basic remote control functions are still available. By using the PCIe optical fiber port, achieving home 10G should not be a dream. Average power: 55w/h per day 55*24/1000=1.32 degrees, my dog misses a steamed bun at every meal
So far, we can count that the numbers are about 10 degrees per day, not including the home switch, monitoring system, and several always-on PCs. So if we calculate these, the average is about 15 degrees of electricity per day. The Tesla Model 3 can run about 100 kilometers now, and some good domestic cars can run 150 kilometers. Adding the car owners of Xuan Yi, Lei Ling, and Corolla driving electric cars, it seems like we could circle the earth once . Calculating like this, a Raspberry Pi could come out in a month. – Raspberry Pi 4B 8G
So returning to the topic of Raspberry Pi, my Raspberry Pi uses a 5V 3A power supply to power the motherboard and a mechanical hard drive, achieving a maximum power output of 5V x 3A = 15W. Assuming the CPU is running at full power, the Raspberry Pi consumes: 15*24/100=0.36 degrees, this is almost negligible in electricity costs. You could even carry a few large power banks, charge them at work, and cycle them to the Raspberry Pi, making the electricity cost almost free.
Many bloggers online are reflecting a fact that, with the improvement of internet speed in China, many people have given up on unreliable cloud storage and chosen to build their own NAS servers. They buy Raspberry Pis or mini-hosts like N100, using mature open-source NAS systems to build their own storage servers, and download many movies they like but never get around to watching. Then this NAS is only shown off when friends come over, and otherwise, it just runs every day doing nothing. For such users, I advise you to stop while you can; when you see your device consuming 10,000 degrees of electricity, you will question your life. Here’s the point: for those who want to assemble an infrequently used small NAS with x86 computers, I advise you to stop. If you must do this, consider looking up the N100 mini-host configuration, which will save energy while not wasting money.
According to online sources, the Kardashian family’s faucet is never turned off, and I don’t know who went to their house to check it or if she said it herself. I don’t understand the world of the rich. Actually, I think 15 degrees of electricity cost is okay, but… if some kind-hearted big brother could give me a Tesla, I would love to charge this 15 degrees into the car and block with everyone on the highway during the National Day. This is similar to how the atmosphere in an internet café is better than playing at home . However, what I currently lack is not 15 degrees of electricity, but a Tesla and a license plate… sigh~
Of course, if we can achieve maximum performance with minimal resources, that would be the best solution. Currently, I plan to phase out the old R730, and I am thinking of the most optimal solution. If any interested friends would like to discuss, please feel free to reach out! The next articles I plan to post will still be related to Raspberry Pi, so if you have any questions, feel free to leave a message or send me a private message through the backend. That’s it, enjoy the holiday!
