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 Infortrend also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can data fragmentation impact data availability and potential loss on NAS Infortrend EonStor GS 3025B devices?

Data fragmentation can have a significant impact on data availability and potential loss on NAS Infortrend EonStor GS 3025B devices in the following ways:

  1. Reduced Performance: Data fragmentation can lead to decreased performance as the system needs to search for and retrieve data from multiple fragmented locations. This can result in slower read and write speeds, affecting the overall performance of the NAS device.
  2. Increased Disk Fragmentation: Fragmented data can also lead to increased disk fragmentation, where files are scattered across different physical locations on the storage disks. This can result in inefficient disk utilization and slower data access times.
  3. Data Loss: Fragmented data can increase the risk of data loss. If a file is fragmented across multiple locations and one of those locations becomes corrupted or inaccessible, it can lead to permanent data loss. The more fragmented the data, the higher the risk of losing critical information.
  4. Difficulty in Data Recovery: In the event of a system failure or data corruption, fragmented data can make the data recovery process more challenging. It may require additional time and resources to recover and reconstruct fragmented files, increasing the potential for data loss during the recovery process.
  5. Limited Storage Capacity: Fragmented data can also result in inefficient use of storage capacity. As files become fragmented, they occupy more disk space due to the allocation of additional storage blocks for each fragment. This can lead to reduced available storage capacity and a need for more frequent disk space management.

To mitigate these issues, regular defragmentation of data is recommended. Defragmentation rearranges fragmented data into contiguous blocks, improving data access times, reducing disk fragmentation, and enhancing overall system performance.

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

Although NAS EonStor GS 3025B 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.

This protects against data loss in case of drive failures and ensures data integrity.

    Overall, RAID technology enhances the performance and reliability of the Infortrend EonStor GS 3025B NAS system by providing data redundancy, increased performance, fault tolerance, scalability, and data protection.

  • What specific RAID levels are supported by the Infortrend EonStor GS 3025B NAS, and how do they affect data protection and storage efficiency?

    The Infortrend EonStor GS 3025B NAS supports the following RAID levels:

    1. RAID 0: This level stripes data across multiple drives without any redundancy. It offers increased performance but does not provide data protection. If one drive fails, all data is lost.
    2. RAID 1: This level mirrors data across two drives, providing redundancy. It offers high data protection as one drive can fail without any data loss. However, it has lower storage efficiency as only 50% of the total capacity is usable.
    3. RAID 5: This level stripes data across multiple drives and uses parity information for data protection. It requires at least three drives and can tolerate the failure of one drive without any data loss. It offers good storage efficiency as it utilizes the capacity of all drives, excluding one for parity.
    4. RAID 6: This level is similar to RAID 5 but uses double parity for enhanced data protection. It requires at least four drives and can tolerate the failure of two drives without any data loss. It offers good storage efficiency, similar to RAID 5.
    5. RAID 10: This level combines mirroring (RAID 1) and striping (RAID 0). It requires at least four drives and offers high data protection and performance. It has moderate storage efficiency as only 50% of the total capacity is usable.

    The choice of RAID level depends on the balance between data protection, storage efficiency, and performance requirements. RAID 0 provides the highest performance but no data protection, while RAID 1 offers the highest data protection but lower storage efficiency. RAID 5 and RAID 6 provide a good balance between data protection, storage efficiency, and performance. RAID 10 offers high data protection and performance but has lower storage efficiency compared to RAID 5 and RAID 6.
