How does the NAS Lenovo ThinkSystem SN850 Blade Server handle encryption and data protection for sensitive information?

The Lenovo ThinkSystem SN850 Blade Server offers several features to handle encryption and data protection for sensitive information. Some of the key mechanisms include:Self-Encrypting Drives (SEDs): The server supports SEDs that provide hardware-based encryption for data at rest. SEDs automatically encrypt all data written to the drive and decrypt it when read, ensuring that the data remains protected even if the drive is stolen or removed.Trusted Platform Module (TPM): The server includes a TPM, which is a dedicated hardware chip that provides secure storage and management of cryptographic keys. It helps to ensure the integrity of the system and protects sensitive information such as encryption keys.Secure Boot: The ThinkSystem SN850 Blade Server supports Secure Boot, which ensures that only digitally signed and trusted firmware and operating system components are loaded during the server's boot process. This prevents the execution of unauthorized or malicious code that could compromise data security.Data Erasure: The server offers secure data erasure capabilities, including the ability to securely erase drives before decommissioning or repurposing them. This feature ensures that sensitive data cannot be recovered from the drives after they are no longer in use.RAID and Redundancy: The server supports various RAID configurations, allowing data to be distributed across multiple drives with redundancy. This helps protect against data loss in case of drive failures, ensuring continuous availability of sensitive information.Network Security: The ThinkSystem SN850 Blade Server includes built-in network security features such as firewall capabilities, intrusion detection and prevention systems, and secure remote management protocols. These features help protect data during transmission and safeguard against unauthorized access.Overall, the Lenovo ThinkSystem SN850 Blade Server combines hardware-based encryption, secure storage, secure boot, data erasure, and network security features to provide comprehensive encryption and data protection for sensitive information.

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 Lenovo 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 data be lost during the process of upgrading or updating the NAS Lenovo ThinkSystem SN850 Blade Server device's firmware?

Yes, data can potentially be lost during the process of upgrading or updating the firmware on a NAS Lenovo ThinkSystem SN850 Blade Server device. Firmware updates involve making changes to the underlying software that controls the device's functionality, and if something goes wrong during the update process, it can result in data loss or corruption.

To minimize the risk, it is recommended to take precautions such as backing up important data before performing any firmware updates. Additionally, following the manufacturer's instructions and ensuring a stable power supply and network connection can help reduce the chances of data loss during the update process.

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

Although NAS ThinkSystem SN850 Blade Server 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.

How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Lenovo ThinkSystem SN850 Blade Server. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

Overwriting during the recovery process;
Loss resulting from bad sectors;
User mistakes.

To create an image, do the following:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Lenovo ThinkSystem SN850 Blade Server network-attached storage keeps LifeLine 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.
