Do I need a NAS?

First explain the situation of the landlord before the group NAS home:

When Millet Router 3 first came out, I started with one. Compared to the previous 89-dollar TP-Link single 2.4 GHz router, I already felt very aggressive. In the beginning, a 160G HITACHI mobile hard disk was purchased for use in 2009. It was used to remotely download movies through Thunder and then samba shared it to Xiaomi's box. At the same time, through the app of the millet router, you can also set up automatic backup of photos from your mobile device to your hard drive.

But gradually found that the disk space is not enough. Then bite his teeth, on the Western Digital red disk 4T, plus an excellent external disk box. There is no problem with normal use. The heat dissipation in the figure above is the heat sink that the landlord took to dispose of the disused motherboard CPU fan. Especially for the millet box, the heat is very important for heat dissipation.

After a period of use, it was found that the classification method of the photo backup of the Xiaomi router was to roughly and roughly archive all photos according to the month. And each user who wants to use the backup function needs to download the Xiaomi router APP, and the permission to open the full disk access is equal to the administrator's permission to the Xiaomi router, which is unbearable. And millet router APP on the use of too many features, each time through the millet router APP into the disk management interface when you need to wait a long time to complete the loading, Thunder remote download can only download up to 3 files at the same time, A lot of restrictions.

Aunt Zhang’s valued friends have often pushed various groups of blacks since long ago. Aunt Zhang also visited the group's boss:

According to Chen’s reply, the group’s practice of shutting down one eye with Black Eyes’s eyes is referring to Microsoft’s practice of that year, and Chen’s boss believes that users with data security requirements have experienced the benefits of Synology. There is a great chance that it will shift to Bai Qunhui. As a "buy software to send hardware," the group Hui has such confidence in his users.

Heart has long been planting grass. So the time is right, let's do it.

First recommend a few forums, these are the landlord once reference and help forum.

NASyun: Black Group

Next Door: China's Largest NAS Forum

Qipo Network: NAS Forum

Black Group Forum

The following articles are valuable to this installment of Black Group Faith. Thank you in advance:

On the DMS installation and debugging, there are many trivial content, where the landlord first talk about the following hardware options, the software will have the time to give you a supplement.

The hardware needed for a black group is almost the same as the content you need to assemble a computer yourself, including but not limited to:

Chassis, motherboard, memory, cooling fan, power supply, hard disk;

There are more value-for-money tyrants will choose HP GEN8 and then carry out the corresponding hardware upgrades, fancy is the rationality of HP GEN8 this brand chassis design. For those users who want to try out Synology, you can choose a cheaper chassis like Joe Sibo.

There was always a group of friends recommending Qiao Sibo's chassis, so this time when choosing a small chassis is also preferred to Joe Schober. With reference to the value of the Friends of the article, in the richest man to start Qiao Sibo C2, with the stand can be put down at least 4 hard drives:

Qiao Sibo C2 chassis

In fact, you don't necessarily have to buy a stand, and the richest family also has a lot of acrylic hard drive stand to sell. If you don't fit it, you can choose your own drawing and then customize it. In the end, I still choose to build a human support, believe in valued friends.

Two vertical stand

Then is the choice of the motherboard, this key component, there are a variety of options, generally choose low-power board, cheap do not believe the evil can go to the richest man Amoy to very cheap industrial control board. However, the basic hard conditions are: low power consumption, at least 4*SATA 2/3 interface+1*M.2 interface+1*PCI interface, Gigabit Ethernet.

Suitable motherboards are:

N3150, N3160, J3160, J1900, 1037U, D525, D2500, E350, J3455, and so on.

We recommend this motherboard: Yuesheng NAS N70E-DR(v3) 6SATA dual gigabit, because he has 6 SATA interfaces, while dual Gigabit, can do link aggregation. But almost no new, so the landlord finally gave up, chose the same currently more recommended ASRock J3455-ITX board, this board comes with 4 * SATA3, use DDR3 (L) notebook memory. In addition to the high prices, there are no shortcomings and meet my requirements. The richest homeowners who have 12 SATA ports on board are coveted but do not dare to easily scribble. Just before the landlord had a 2G Samsung DDR3 1333 memory on a small black laptop, it could come in handy and use it on the NAS.

ASRock J3455-ITX Motherboard

On the NAS big head hard drive, the landlord had purchased a rainbow home 4T red plate before, thinking about group NAS, not on RAID is really boring, so the arm is gone, and then under the two rainbow 4T red plate.

The first rich family into two Western Digital 4T red disk

Prepare for the most basic soft RAID 5 via 3*4T components. Afterwards, even though RAID5 is actually very insecure through the Internet, so a Seagate Cool Hawk 4T is installed in the superior mobile hard disk box as a cold backup. The Synology 6.02 system has a suite called Hyper Backup. You can choose to automatically back up the data in Synology's system to an external mobile hard disk. On the two groups of Hui Hui to do backup each other is too much, a single group Syni RAID5 do not trust, so do more than one important data of cold standby is more needed.

Seagate Cool Eagle 4T

Since the power of the group's daily use will not be too large, it is not too hard to argue with 1W for 1W. It is enough to choose one, so it is an ordinary power supply for the following orders:

Xingu Power Supply

Later feeling needs to be on a UPS uninterrupted power supply, otherwise sometimes power failure or damage to the disk array is still relatively large.

After the introduction of the selected hardware, the next installment will be liked:

Start U disk I have a discarded U disk, that is, before I appeared in the university in the EDC to buy, was a liar business from 4G brush into 8G, the shell has been damaged, also spent a lot in the Washing Machine swimming Kingston U disk.

The machine lit up once. The landlord did not purchase a cooling fan. Personally feel that there is no need for active heat dissipation for this low-power board, and the power supply itself has a 12-inch fan, which is used to passively dissipate other components. enough. And according to the daily use of the landlord, the two hard disks installed on the stand are usually at a normal temperature of about 39 degrees, while the hard disk on the front panel bracket of Qiao Sibo has a slightly higher temperature, which is about 43 degrees. It is in an acceptable range.

The process of installing the black group DSM_DS3615xs_8451 version can refer to the group's value-friend tutorial. Regarding the black group Huiji number, I can't figure out the results of the offline calculation. I was fortunate enough to find a tutorial and posted the latest one. Black group Hui online calculator, here I share to everyone:

Black Group Online Calculator

Pro test available.

In addition, on the question of the group's MAC address, in fact, as long as the mac's first six are: 00-11-32-xx-xx-xx, the latter six can be modified according to their own preferences. The pro-test can be registered with the S/N number quickConnect calculated by the above black group operator and successfully washed.

Black group wash white quickconnect

Then a lot of people on the Internet said that it is best not to use quickconnect, and it is worth having friends share a tutorial on how to penetrate TCP in the intranet. The landlord has bought a .win domain name in Alibaba Cloud for 10 years. Next, we're ready to abandon quickconnect, a very handy feature. After all, I'm Black Group Fai, and I can't justify the resources of the white-skirt user.

Purchase History

Expiration record

OK. Then on the NAS, the landlord found that the problem has arisen again. The WAN/LAN port of the Nima Millet Router 3 is 100Mbit/s. Although this is enough for most families in China, after setting up the NAS, is it still possible to use 100M Ethernet? Can't explain! So the landlord is determined to change routes!

In the NETGEAR and ASUS landlord tangled for a long time, because it is ready to brush Meilin firmware, generally reflects the support of Asus to Merlin is better, brush Merlin is also very convenient, so decided to enter Asus, but Asus AC68U, AC66U B1, two The difference between the 100 or so. The general feedback from the koolshare forum is that the AC66U B1 and AC68U are basically the same in hardware configuration and the board USB layout of the AC66U B1 is more reasonable. Although it seems to disassemble, the former king AC68U's materials work better, and Vertical heat dissipation is better. However, the AC66U B1 can also release depressive nature by brushing Merlin's firmware. Wireless can also reach 1900M. And everyone said that buying new electronic products do not buy the old, so the landlord by Jingdong's 100 yuan voucher obtained by the trade-off loophole, in the dark night of high winds a month, under an AC66U B1.

ASUS AC66U B1

At first glance, I feel that I feel good and low-key, and the texture of the metal, the large heat sink group, and the plastic feeling of the previous millet router 3 are not as small as the average. And Gigabit WAN/LAN meets LAN transmission needs. On the intranet speed, the landlord slightly measured through my little black Gigabit wired connection routing, copy 2G files to the laptop's sandisk SSD, the speed is about 70MB/s up and down, and value-friends still have a certain gap . Try to turn off the firewall anti-virus software, the speed is a bit faster, but still not faster.

Then the home network, the landlord also needs a switch, previously had a 5-port 100 megabytes, it seems to have to follow the change, so on this:

Tenda 5-port Giga-iron shell exchanger

Iron shells in your hands are not the same. Feeling heavy.

With regard to the convenient use of the DSM software, the landlord felt that it was complicated and complicated, and he had not fully understood it, so it was not involved. But the photo station, the video station, the cloud sync, the cloud station, the download station, and the docker's whole family bucket are really super easy to use!

With regard to the array selection of Synology Systems, the landlord suggested that you have RAID 5 on RAID 5 and that the capacity for hard disk expansion is not enough in the future. It is better to be able to use RAID6. Of course, this usually requires a disk array card. Then everyone on the Internet said that they should not use SHR's own SHR. Of course, this is a matter of opinion. For those who have a lot of hard drives with different capacities, the group SHR ​​is certainly a better choice. The format of the file system, Synology is based on Linux, then surely can be on ext4, but the landlord later found that when using docker, asked me to brtfs, but all my disk space has become ext4, This time I was dumbfounded. Therefore, all can only be re-engaged, this time the landlord has all been on the brtfs. The file system of the last file system, the landlord has not studied in depth. But since the current docker does not require docker requirements must be on the britfs, then there must be its reason.

On the hard disk, the landlord bought the dog and the richest man in the country. They are not self-operated or flagship stores. The two purchased red disks have different appearances. There is an online teaching how to discriminate between genuine and fake red disks. The landlord looks at the black spots on the surface of the red disk that it says, and finds the ones purchased in Dogdong and the fake red disks. The characteristics are the same, but later on the Internet to teach Western Digital's official website, register an account and then through the hard disk S/N and the back of the PCB serial number for product registration, as long as the registration can be guaranteed to be genuine, so the landlord to try it out , Found that all three red disks can be registered, so simply judging by the appearance of whether the real red disk is not desirable, because the batch may have different specifications.

Three red plates can be successfully registered

The entire system was replaced, the landlord's investment is probably:

Chassis: Qiao Sibo C2*1 = 155

CPL Filter

Circular polarizing filters, namely circular polarizing filters. It is mainly used to eliminate polarized light, increase color concentration, deepen sky blue, highlight white clouds, and eliminate reflected light on non-metallic surfaces such as glass or water surface. It can also reduce the soft focus caused by atmospheric fog in landscape photos, but does not change the tone balance of the whole picture.
Linear polarizer, also known as ordinary polarizer, is marked in English as l-pl (UNEAR Polarizer) or PL-L (polarizing F, ilter linear), pllineat, PL, pol, CPL.
CPL structure: it is divided into two pieces. When in use, the back piece is screwed in front of the lens group in front of the lens, and the front piece is rotated. Different angles have different effects on photometry and saturation. It is generally used 90 degrees from the illumination direction to maximize the effect. Generally, it will reduce the 2nd gear exposure and affect the saturation. However, it should be noted that if you want to take beautiful reflections in the water or metal highlights, do not use them. It will eliminate these reflections and you will not get the image you imagine; But if you want to take pictures of fish in the water, algae in the pond, or exhibits in the window, CPL is a good choice. Taking a portrait with CPL will eliminate the highlights on the face, reduce the contrast, and make people's face look flat. See if you need special effects. It is necessary to free up one hand during CPL adjustment, so it is best to use it with tripod and shutter cord.
Role of CPL polarizer: polarizer can eliminate harmful reflected light and improve image clarity and expressiveness. Eliminate reflected light: eliminate light reflected from shiny surfaces such as water or glass. Increase color saturation: it can make the blue sky, green leaves, ridges and buildings more colorful. Circular polarization CPL is specially used for AF focusing camera and digital camera, which is more convenient for rotation adjustment. In addition, it is also compatible with MF manual fuselage.
