Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Qsan also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any limitations or restrictions on file or folder names that can cause potential data loss on NAS Qsan XCubeNAS XN8024R devices?

Yes, there are certain limitations and restrictions on file and folder names that can potentially cause data loss on Qsan XCubeNAS XN8024R devices. These limitations and restrictions include:

  1. Length Limitation: The maximum length for a file or folder name is 255 characters. If a file or folder name exceeds this limit, it may cause issues with accessing or managing the file or folder.
  2. Character Restrictions: Certain characters are not allowed in file or folder names, including: / : * ? " < > |. Using these characters may result in data loss or corruption.
  3. Reserved Names: There are certain reserved names that cannot be used for file or folder names, such as CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Using these names may cause conflicts and potential data loss.
  4. Case Sensitivity: Qsan XCubeNAS XN8024R devices are case-sensitive, meaning that "file.txt" and "File.txt" are considered two different files. This can lead to confusion and potential data loss if files or folders are not named consistently.

It is important to follow these limitations and restrictions when naming files and folders on Qsan XCubeNAS XN8024R devices to avoid potential data loss or corruption.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS XCubeNAS XN8024R can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

    The Qsan XCubeNAS XN8024R supports multiple RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60.

    • RAID 0: This level offers no redundancy and striping of data across multiple drives. It provides improved performance by utilizing multiple drives simultaneously but does not provide any data protection. If one drive fails, all data is lost.
    • RAID 1: This level mirrors data across two drives, providing redundancy. If one drive fails, the other drive contains an exact copy of the data. It offers good data protection but does not provide any performance improvement.
    • RAID 5: This level distributes data and parity across multiple drives, providing both data redundancy and improved performance. It requires a minimum of three drives and can tolerate the failure of one drive without data loss. However, during a drive rebuild after failure, performance can be reduced.
    • RAID 6: This level is similar to RAID 5 but with double parity. It requires a minimum of four drives and can tolerate the failure of two drives without data loss. RAID 6 offers higher data redundancy but may have slightly lower performance compared to RAID 5.
    • RAID 10: This level combines mirroring (RAID 1) and striping (RAID 0). It requires a minimum of four drives and provides both data redundancy and improved performance. It can tolerate the failure of one drive in each mirrored pair without data loss.
    • RAID 50: This level combines striping (RAID 0) and distributed parity (RAID 5) across multiple RAID 5 arrays. It requires a minimum of six drives and provides both data redundancy and improved performance. It can tolerate the failure of one drive in each RAID 5 array without data loss.
    • RAID 60: This level combines striping (RAID 0) and double distributed parity (RAID 6) across multiple RAID 6 arrays. It requires a minimum of eight drives and provides both high data redundancy and improved performance. It can tolerate the failure of two drives in each RAID 6 array without data loss.

    In summary, the different RAID levels supported by the Qsan XCubeNAS XN8024R offer varying levels of data redundancy and performance. RAID 0 provides no data redundancy but improved performance, while RAID 1 offers full redundancy but no performance improvement. RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 provide both data redundancy and improved performance, with varying levels of fault tolerance. The choice of RAID level depends on the specific requirements of the user, balancing the need for data protection and performance.
