IntroductionAdvantages of NAS

Currently, the volume of data grows exponentially, so we need a high-power, reli-able memorizer. Nowadays, more and more people begin to attach importance to and believe in the advantages of NAS (network-attached Storage).

Compared to the public cloud, NAS is easier to control, especially the speed of data transmission is faster than same kind of products. During uploading and reading, the use of public cloud services will be limited by the network, but NAS won’t.If you need multiple devices to access and play a 4k video, NAS would be a good choice.

NAS is private to the user, which makes the data stored in it more securely. And some hidden dangers of data can be avoided, such as Network Virus, Network At-tack, Information Disclosure and so on. All you need to do is make sure that the data you upload is safe.

Compared with the mobile hard disk, NAS has a more convenient way of data shar-ing and access which benefits you when you and your colleagues are in a hurry to copy the same files.

Frequent use of hard disk interfaces is likely to cause wear and lead to poor contact. It is inconvenient for you to access a file on different devices, such as computer, tablet, mobile phone, etc. Accessing and sharing a large number of files, exchang-ing files with multiple terminals (multiple devices) needs you to have a NAS server.

About OMV

OMV (OpenMediaVault) is a next generation of open source network additional storage solution (NAS) based on Debian Linux. It includes services such as SSH, (S)FTP, SMB/CIFS, DAAP media servers, RSync, BitTorrent clients, and more. It also fea-tures a modular design framework that can be enhanced by plug-ins. OpenMed-iaVault contains the following cores:

﹒ Debian Linux (Squeeze) system (i386 or x64)

﹒ Web-based system management

﹒ Simple system upgrades through Debian packages

﹒ user management

﹒ Task scheduler

﹒ Multilanguage support

﹒ Service bulletins based on DNS-SD (Apple's protocol)

﹒ Service Bulletins

Next, we introduce how to install OpenMediaVault on Raspberry Pi 4 so as to install NAS server. As a NAS system, there is no doubt that OMV is excellent.

⑤②

Acrylic plate:

① TOP plate

② MIDDLE plate

③ BOTTOM plate

④ FAN-FIXED plate

⑤ Button particles

2. Put the Raspberry Pi (with three heat sinks attached) on the MIDDLE plate and then screw it with M2.5x11mm Double-pass nylon standoff.

Notice that the SD card faces towards the left of the plate.

3. Screw the NAS HAT module into the Raspberry Pi with 4 M2.5x6mm crews.

4. Place these four M3x13+6mm ny-lon standoffs at bottom of the MID-DLE plate, while put the 4 M3x26 nylon standoffs over the MIDDLE plate. Then screw them all firmly.

1. On the MIDDLE plate, we screw 4 M2.5x6mm and 4 M2.5x8+6mm nylon standoff.

We need to not ice the assembly direction of parts: the triangle should be at the left of center of the plate and one of the rectangles is in upper left corner of the plate and other is in the bottom right corner of the plate.

6

7.According to the direction notice shown by the picture, put the four button particles into the slots.

Notice the rectangles remarked by blue boxes.

5. Assemble the dual fan and FAN-FIXED plate with the M2x12 screws and M2 nuts.

We should let one fan rotate clockwise and the other anticlockwise to help form the back flow of air, so we should note that the assembly direction of these two fans are different.

6. Let dual fan wire up to the power out-put port of the NAS HAT and insert the dual fan into the rectangular slots of the MIDDLE plate.

8. Flip the TOP plate. The two fans can be properly assembled in the rectangular slots of the TOP plate.

You can tape the 4 button particles to avoid falling.

11. Fix the BOTTOM plate with M3x8mm screw to complete the NAS-KIT body.

Note that the orientation of the hard disk should be the same as that of USB slot of Raspberry Pi.

12. Connect power cord, hard disk wire and internet wire to the Raspberry Pi 4.

10 . Screw the hard d isk and the BOTTOM plate with M3x8mm screws.

The screw holes on both sides of the interior of the BOTTOM plate are not completely symmetrical. Please make a slight comparison before assembly.

9. Fix the TOP plate with four M3x8mm screws.

Click Access Rights Managemer-Group, click Add -> General and then Name and Comment. Here we create an user group team.

Select the two users, sunfoudner-1 and sunfounder-2 we just created in Members interfaces, then click save so as to add two members sunfounder-1 and sunfound-er-2 into the user group.

12

When you click the Privileges on the top, a window pops up on which you can set different access permission for different users or user groups. For example, you can set read-write permission for sunfounder-1，sunfoudner-2 and a certain team group.

Add a Shared Folder

Click Access Rights Managemer ->Shared Folders, then click Add button and type in the name. After that, we choose hard disk devices. The path will be automatically generated by the system. You need to click save after we finish the configuration.

At this point, we can create a shared folder called share on hard disk 123.

13

Select the Shared folder, click the ACL above, and set user permissions on the inter-face.

Here, we set the read-write access permission for sunfouder-1 and the read-only permission for sunfounder-2.

Please Apply it.

During the installation, there pops up a prompt at the top of the browser:

The configuration has been changed. You must apply the changes for them to take effect.

The users who has the permission to Read/Write the files can add or download the files.

The user who has the Read-only permission can only download the shared files.

NAS HAT PageThere are 3 display pages and a menu page.

Display Page:

While booting the device, we can see that the initial page (display page 1) has the character “BASIC INFO”. This page is used to display the IP address, the usage rate of CPU and RAM and the total .

The page “DETAILED INFO” (display page 2 is the page we can enter by pressing “+” on the page 1 or clicking “-” on the display page 3) mainly displays the temperature of CPU and GPU, the work and power of fans even the percentage of fans.

NOTE: When the average temperature of CPU or GPU rises up to 54 ° , the fan starts working; meanwhile, the LED in the bottom right corner will turn on.

The page “DISK INFO” (display page 3 is the page we can enter by clicking “+” on the page 2 or clicking “-” on the display page 1) mainly displays the SD card, disk capacity and its usage rate.

21

Menu Page:

The page “MENU INFO” (we can enter the menu page by pressing the “BACK” button continuously for two times on the display page. We can return to the dis-play page by clicking “BACK” button for one time on menu page. )

We switch to different options by pressing “+” or “-” before we press “OK” to select the certain option.

1.Shutdown2.Reboot3.Background color4.Page always refresh: choose OK to automatic mode and NO to manual mode. For your lasting use of NAS HAT, We recommend to set manual mode.

In addition, the feedback from the screen under the manual refreshing mode is not so fast as that under the automatic mode. Under the mode of manual refreshing, the button on the screen responds to your pressing till there appears a mark S in the top left corner of the NAS HAT.

NOTE: If you want to make some adjustment for the menu page, you can change the raspi_omv_main.py file under the directory ~/nas-kit/main in the Raspberry Pi system. If you want to know more about it, you can access https://git.io/JeAoI to check the development files.

Under the automatic mode, the NAS HAT refreshes itself once every 500ms, but you need to press the button “OK” to refresh under the manual mode. Pressing the buttons +/-/BACK can let you enter other pages, so it can refresh different options on different pages at the same time.
