First talk about the landlord experience, nas has n times grass, has purchased time capsule, d-link share center, Synology DS216 It is convenient for everyone to configure first and then skip to the end without watching the process: CPU: G1840 200 yuan; Motherboard: ASRock B85M-Pro4 199 yuan second-hand; Chassis: tt v21 299 yuan; Power: Xin Gu 350w 130 yuan; Memory: Kingston 4gX2 old accessories do not know the price; The shortcomings are obvious. Your death is due to death. At that time, mbp was brainwashed by a time machine. It was an apple brain residue for a while. It was compatible with Apple. Others were unfriendly and the function was nothing. The advantage is durable, easy to use, or the router provides a stable access function, simple upgrades, do not like tossing shoes preferred. Disadvantages: It may be the reason that it just came out. Firmware is hard to say, the function is very general, and then there is no online update. Security is a big problem. Advantages: Stable, no problem for more than four years, the focus is hard disk dormancy well, hard disk no problem. Disadvantages: lying, this is called the first NAS system in the universe can be toss me bad, replaced the three hard drives, I have gone under the 3T movie, md hit this group of things in my life I hit the hard drive suicide . Advantages: I have to say that the system can be updated online, the interface UI is very friendly, you can synchronize Baidu cloud, for people who do not code can play a lot of open source good things through the mouse. A group of Fai dog's broke my hard drive again, and the recovery of this system is very fucked. For Xiao Bai, it is a group of Fai who needs to be cautious. The broken hard drive must first find the after-sales service. Don't toss it yourself. It is installed. Will format the entire hard drive! 2 used these nas children's shoes should know that copying data from these is a very painful thing, especially when the data on the T, is mainly subject to a circle from the network card, the motherboard constraints, can not be directly copied, right There may be children's shoes do not know the above usb socket can only be used to test into the test does not come out, I feel deeply happy, not reach the maximum transmission efficiency copy of so many documents one night is not enough, with publicity There is a gap in the transmission rate. 3 startup speed is too slow tmd, of course, as nas generally do not shut down, but this performance is really low, but the sharing of software should be enough 4 storage, I actually used the basic or did a soft raid, which means that regardless of your entire storage data partition is a soft raid partition, which means that when you remove the hard disk no way to read on other machines , mac and win will not work, it's own system partition but there is no problem, with the mdadm tool for Linux is possible, but I did not succeed in the latest 16.04 operation, there is a big trouble to know to introduce, do not know if it is with me The virtual machine has a relationship. 5 The big guys who saw the diy found most of the nas functions under win, and hype-v this artifact, and long grass. It doesn't touch winS for years. If you just share files and simple backups, d-link is very cost-effective, and it's enough. The router is not considered as NAS here, although I am also playing. If you play more time, like toss but lack of it based on the recommended group Hui, entry curve is indeed low, and most of the functional white and no pressure. There is a certain it based on the DIY machine is absolutely preferred, you can get several times the performance and workmanship with the price of Qunhui half, said that the group of Hui more stable I can only smile. The motherboard of the diy machine is ASUS, and the system is Microsoft's. It is the strongest combination in the world. ? ! ! Not used windows server recommended first use windows10, most features have, ws preferred 2016 Standard Edition, start speed seems to be faster than 10, with data deduplication and file sharing access control, the most cattle is also supported quota control ~~~! ! ! The small group of Hui also jumped out and said I also have it, there are your sister, people have quotas are hard and soft, but also supports branchcache. System I chose the Windows Server 2016 Standard Edition, really if not to re-use these features, with win10 very good province toss, but I like tossing, and the server system is more suitable as a long-running host, such as background programs Higher priority. From Joe's undead series to Yinxin, they finally read the tt's v21. We have more detailed information about the chassis that can be used to move on to other posts. Here I talk about v21. V21 is very large, very large, very large; very square, very square, very square, look at the picture to feel about it. The function is strong, very strong, very strong; very quiet, quiet, quiet; important things have to be said three times. The big is really big, the height is generally two-thirds of the whole tower, and the width is one-third wider than the whole tower. It is square in front. Because of the large side because it can be adapted from the nas to the main machine requires a variety of customized solutions, how do you want to engage in how, 3.5 hard drive three 2.5 hard drive three, I also diy out three 3.5, so long as Sata mouth enough, plug in 10 hard drives are possible. As nas there are several advantages of it: 1 horizontal chassis fits everywhere, even local tyrants can stack multiple sets => native support! 2 twenty centimeters big fan, ah big fan, only 800 rpm, the sound is not small, the noise is mainly cpu fan and hard disk sound, huh, huh, for the performance party it can install n fans, you read it correctly n I really do not want to count how many. . . 3 can be installed mATX motherboard, everyone is using itx, but unfortunately I am cost-effective party, the performance can not be too bad, itx's choice is too tmd less, mATX is much more, and more means that affordable, 4 dust magnetic network This thing is good, easy to clean, nas necessary 5 almost forgot to say, disk position! How can you reduce the number of NAS positions, especially if you don't have a 45,678 disk? ASUS mATX 6stata can not be wasted 6 support full-size graphics card, playing gpu programming and rendering of high-end users must have ~ Disadvantages: After the tape in the head figure was taken down, it was found that the logo was a weak magnet and sucked on it. It was necessary to do so. I really wanted to fix it with glue, but I also gave it a chance to change the logo. Haha. There are two dust-proof nets at the bottom and at the back. Although the interior should be under negative pressure, there are always two less feelings. Said earlier, itx choose too little, the motherboard is set after the v21 motherboard like to choose, and finally my motherboard is B85M Pro4 second-hand income, recommended ASRock motherboard, sata mouth more, the network card is I217-V, of course, must Gigabit card does not explain this, do not know their network card model can go to the official website to find system information, if not to find information on the general will find the dismantling of the 8 series are mostly my network card model. Why do you want to check the network card, because the intel chipset is personal, specifically in this network card driver shielding the winows server support, how to crack please Baidu Physical layer backup: host hard disk + offline hard disk (that is, optical hard disk, insert the backup) + CD (preferably place a different place); add CD is the main anti-electromagnetic damage, do not disagree, and now from the cell phone signal to Wifi signal to the solar storm are influential (earthquake belt children's shoes even more, the disk is fragile, Ya'an dug out of the disc can also be used!) ~ Blu-ray disc as a chemical medium is also so cheap and no reason not to use It. Host internal backup (available in many places to easily backup this software referred to qs): 1 system backup: qs and smell the dead system can do it, in front of said that which is strong software development, I believe the most death, comes with a variety of recovery and restore points, so use qs or smell Let's look at personal preference to death. If it is used to smell the software and system installed when all installed in the c drive, backup c drive as a full backup, otherwise it will go wrong, my nas addition to the necessary software, qq-guards are not installed. 2 Data Backup: qs has synchronous and mirrored backups. The fact that the group's disaster in front of the group actually says plainly is how much data can be recovered in the event of a disaster. How much can it be recovered if some of the damage occurs? There are children's shoes that there is enough backup, backup itself is a risk, such as the use of hard array, array card if you can not replace the same data is abolished, and then for example, group hui, sb system with linux madam made a soft raid, How many children's shoes will be Linux, how many will madam? Therefore, without encrypting bare file storage without raid, you can recover a lot in the event of a disaster. The synchronous backup of qs will be able to do this, and it also solves the risk of the image backup being not timely. In turn, the mirror backup is also necessary, and its real-time performance is not high. , High backup efficiency, multi-version backup, and consistency check, the two are very complementary ~! The backup is distributed as evenly as possible on several hard disks to reduce the burden on the hard disk and the backup efficiency is higher. I forgot to mention that the mirror backup can be executed at regular intervals. qs is so strong. Windows server2012 file from this piece is getting more and more powerful, and now can be modified and written separately, such as I worry that parents will accidentally delete files, then only to read and write functions. The function of file quota can limit the data monitored by the camera without worrying that the hard disk is full. The group's projection function and movie cover function are really easy to use, so it's necessary to do a good job because it is a Linux kernel. It has strong performance and no feeling of running. It has a delayed start function for hype-v, so the system The start-up time was not as slow as the group's fading. Ubuntu also has to be installed, personal preferences, and I use tossing, also used to deploy docker, I know it can docker smelling death, this is not a personal preference. Windows10 has not been installed, consider the back of the tablet to access, and temporarily home tablet is not in use, did not go to install. In fact, the effect of win10 on TV is also very good. Said before the power consumption, to see personal needs, we must seek more than led also power saving, then you can only choose itx, I think this kind of Celeron is the most suitable for me, the price is only two hundred, after not enough to use more As long as it is 1150 stitches, there is still room for digging down the actual performance, tdp is 35w. A nas main power is the cpu, the hard disk to check a lot of information, the average power is below 5w, the actual copy power is about 12w, ssd is less than 3w. The actual power consumption of my configuration is about 45w, 1ss+3hdd, and about 300 yuan a year. Since the development of hardware, the quality of diy has been very mature. Therefore, it is the first choice to use the existing hardware on hand. If there is no suitable old computer, if there is no suitable one, there will always be friends around. To collect old hardware can give diy Save a lot of money. Here is the most difficult to put together is the motherboard, tower chassis motherboards are relatively large, nas get a big machine is always not good-looking, I am such a value control to more than half of the funds are bought a chassis. The entire NAS only bought a new motherboard and chassis. The main board can consider salted fish, as long as the model is too old and it can be new in about two years.
