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.

Can the use of specific data compression or deduplication techniques impact the performance and data integrity on NAS Qsan XCubeSAN XS5216 devices?

The use of specific data compression or deduplication techniques can impact the performance and data integrity on NAS Qsan XCubeSAN XS5216 devices.

Data compression techniques aim to reduce the size of data, which can result in improved storage efficiency and reduced bandwidth requirements. However, the compression process requires additional CPU resources, which can impact the device's overall performance. If the device's CPU is not powerful enough or already heavily utilized, enabling compression may lead to slower data transfer speeds and increased latency.

Deduplication techniques eliminate redundant data by storing only unique data blocks. This can significantly reduce storage capacity requirements and improve efficiency. However, the deduplication process also requires additional CPU resources and can impact performance. Additionally, if the deduplication algorithm is not implemented correctly, it can potentially lead to data integrity issues.

It is important to carefully evaluate the capabilities and limitations of the specific data compression and deduplication techniques supported by the Qsan XCubeSAN XS5216 devices. Consider factors such as the device's CPU power, available memory, and workload requirements before enabling these features. It may be necessary to perform thorough testing and monitoring to ensure that the chosen techniques do not negatively impact performance or compromise data integrity.

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

Although NAS XCubeSAN XS5216 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:

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

Where are user’s files stored?

The Qsan XCubeSAN XS5216 network-attached storage keeps SANOS operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
