How to recover data from NAS Qsan XCubeSAN XS1226

Recover data from damaged RAID arrays inaccessible from a computer.

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 known limitations or performance bottlenecks that can increase data loss risks for NAS Qsan XCubeSAN XS1226 devices?

There are several known limitations and performance bottlenecks that can increase data loss risks for NAS Qsan XCubeSAN XS1226 devices. Some of them include:

  1. Insufficient redundancy: The XS1226 device may not have sufficient redundancy in terms of hardware components or RAID configurations. This can increase the risk of data loss in case of hardware failures or disk failures.
  2. Lack of backup mechanisms: If proper backup mechanisms are not in place, such as regular backups to external storage or cloud storage, data loss risks can increase. In the event of a catastrophic failure or accidental deletion, there may be no way to recover the lost data.
  3. Inadequate network infrastructure: If the network infrastructure supporting the XS1226 device is not properly designed or lacks sufficient bandwidth, it can lead to performance bottlenecks and data loss risks. This is especially true if multiple users or applications are accessing the NAS simultaneously.
  4. Lack of monitoring and alerts: If the XS1226 device does not have proper monitoring and alerting mechanisms in place, it may be difficult to detect and address potential issues that can lead to data loss. For example, disk failures or high disk usage may go unnoticed until it's too late.
  5. Inadequate security measures: Insufficient security measures, such as weak passwords or lack of encryption, can increase the risk of unauthorized access and data loss. Malicious actors can exploit vulnerabilities in the system to gain access to sensitive data or delete important files.

It is important to note that these limitations and performance bottlenecks can be mitigated by implementing best practices such as regular backups, redundant hardware configurations, monitoring systems, and robust security measures.

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

Although NAS XCubeSAN XS1226 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.

Questions and answers

  • What is SSH and how does it work in the context of network security?

    SSH stands for Secure Shell. It is a cryptographic network protocol that provides a secure way to access and manage remote devices over an unsecured network.

    In the context of network security, SSH works by establishing an encrypted connection between a client and a server. This encryption ensures that the data transmitted between the client and server remains secure and cannot be easily intercepted or tampered with by malicious actors.

    SSH uses public-key cryptography to authenticate the client and the server. When a client wants to connect to a server, the server provides its public key to the client. The client then uses this public key to encrypt a random session key and sends it back to the server. The server, having the corresponding private key, can decrypt the session key and use it to establish a secure connection with the client.

    Once the connection is established, SSH encrypts all the data transmitted between the client and the server, including commands, passwords, and files. This encryption prevents eavesdropping and protects sensitive information from being exposed.

    SSH also provides additional security features such as port forwarding, which allows secure access to services running on a remote server, and key-based authentication, which eliminates the need for passwords and provides an extra layer of security.

    Overall, SSH is a widely used protocol in network security as it ensures secure remote access to devices and protects sensitive data from unauthorized access.
