## Introduction to the ADMIN interface and instructions for initializing hard drives using NextNAS:

**NextNAS** is an abbreviation for [Network-attached storage](https://en.wikipedia.org/wiki/Network-attached_storage) which is a file-level computer data storage server connected to computer network that provides data access to a heterogeneous group of customers. NextNAS specializes in serving files by hardware, software or configuration.
### a.Admin interface:

- Used for administrators to manage files, install, add, edit, delete applications. When accessing the device for the first time, you cannot access ADMIN.

- To access ADMIN, you need to initialize the storage hard drive to store the application by accessing the NextNAS.

### b.Instructions for accessing NextNAS:

At the main interface, click on the NextNAS icon:

![[Pasted image 20240315164235.png]]

After accessing the NextNAS, you will see the login interface, you need to log in to the NextNAS

![[Pasted image 20240503162403.png]]

After successfully logging in, you will go to the main interface of **NextNAS:**

![[Pasted image 20240315164522.png]]

Here, we can see some information such as:

- **Hard drive information:**

![[Pasted image 20240315164543.png]]

- **System partition:**

![[Pasted image 20240315164601.png]]

- **Memory storage:**

![[Pasted image 20240315164654.png]]

### c. Instructions for initializing hard drives using NextNAS:

At the main interface of the NextNAS, access the **Storage** section in the navigation bar:

![[Pasted image 20240411194046.png]]

At **Storage**, you can see many sub-sections:

- **Disks**:

![[Pasted image 20240315164916.png]]
<center>QEMU is the system drive<center/>

You can check the information of each drive (capacity, drive name,...)

- **S.M.A.R.T**:

  - In the **S.M.A.R.T** section, you will check whether the quality of the hard drive is still good or not, whether there are data errors or not.

  - Click on the **Device** subsection in the **S.M.A.R.T** section, you can see information such as:

![[Pasted image 20240315165130.png]]

- **Status** of hard drive:

-- If the display status is green => the hard drive's condition is still good

-- The display status is yellow => the hard drive is at risk of failure, you should replace it with another type of drive to avoid data loss.

- In the **Software RAID** section, we can create a **RAID** partition:

![[Pasted image 20240315165758.png]]

**So what is RAID?**

 RAID is the abbreviation for [Redundant Array of Independent Disks](https://vi.wikipedia.org/wiki/RAID) - A form of combining multiple physical hard drives into one system. Previously, RAID was used as a data backup solution, allowing data to be simultaneously written to multiple hard disks. Until now, besides the above Backup role, RAID has many variations that allow significantly increasing the ability to retrieve data from hard disks.

-- Create RAID:

o   At the interface, click on the “+” sign as shown:

![[Pasted image 20240411194212.png]]

o   In the **RAID** creation section, you need to choose the **RAID** type, there are many types of **RAID**, in this article, we will use RAID 5 *(need at least 3 hard drives with same capacity or more, 2 drives are combined together to get total capacity and 1 spare drive)*. In addition, you can learn more about other types of RAID at [here](https://www.phucanh.vn/cac-chuan-raid-pho-bien-tren-he-thong-may-server.html) .

![[Pasted image 20240411194310.png]]

![[Pasted image 20240411194351.png]]

Then, we will select the drive:

 + What is SMB sharing?
  + SMB (Server Message Block) is a network protocol used to share files and devices within a network. It is mainly used in Windows operating systems to allow different computers to access and share resources such as files, printers and folders. The SMB protocol plays an important role in connecting and sharing information between computers in the internal network, facilitating work and data transmission in a group work environment. You can learn more about the SMB protocol at [here](https://viettuans.vn/smb-la-gi#:~:text=SMB%20(Server%20Message%20Block)%20l%C3%A0 ,m%C3%A1y%20in%20v%C3%A0%20th%C6%B0%20m%E1%BB%A5c.)
