How to recover data from NAS Uniview VX1616-C

Uniview VX1616-C NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VX1616-C.

How to recover data from NAS Uniview VX1616-C

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

Questions and answers

  • What is iSCSI and how does it work in the context of network storage?

    iSCSI (Internet Small Computer System Interface) is a protocol that allows storage devices to be accessed over a network using the SCSI protocol. It enables the connection of storage devices such as hard drives, tape drives, or solid-state drives to a network, making them accessible to multiple servers or clients.

    In the context of network storage, iSCSI works by encapsulating SCSI commands and data into IP packets, allowing them to be transmitted over an Ethernet network. It utilizes the existing TCP/IP infrastructure, making it compatible with standard Ethernet networks and allowing storage devices to be accessed remotely.

    To establish an iSCSI connection, a client (initiator) sends an iSCSI command to a storage device (target) over the network. The target responds by executing the command and sending the requested data back to the initiator. This process is similar to how a local storage device would communicate with a server or computer directly connected to it.

    iSCSI can be implemented using dedicated hardware or software initiators. Hardware initiators are specialized network interface cards (NICs) that have built-in iSCSI capabilities. Software initiators, on the other hand, are software components that run on the client's operating system, utilizing the server's network interface for communication.

    Overall, iSCSI enables the consolidation of storage resources, simplifies storage management, and allows for flexible and scalable network storage solutions. It is commonly used in enterprise environments where centralized storage systems are required.

  • Can you explain the benefits and drawbacks of using iSCSI for storage networking?

    Sure! iSCSI (Internet Small Computer System Interface) is a protocol that allows the transmission of SCSI commands over IP networks. Here are the benefits and drawbacks of using iSCSI for storage networking:

    Benefits of iSCSI:

    1. Cost-effective: iSCSI utilizes existing Ethernet infrastructure, eliminating the need for dedicated Fibre Channel (FC) networks. This makes it more cost-effective for small and medium-sized businesses.
    2. Flexibility: iSCSI can be used over long distances and can connect multiple storage devices and servers, providing flexibility in storage network design.
    3. Scalability: iSCSI supports the use of multiple initiators (servers) and targets (storage devices), allowing for easy scalability as storage needs grow.
    4. Compatibility: iSCSI is compatible with various operating systems and can be used with both block-level and file-level storage.
    5. Data protection: iSCSI supports features like data encryption and authentication, ensuring secure data transmission over the network.

    Drawbacks of iSCSI:

    1. Network dependency: iSCSI relies on IP networks, so any network issues like latency, congestion, or packet loss can affect storage performance.
    2. Performance: Although iSCSI performance has improved significantly over the years, it may still not match the high throughput and low latency of dedicated Fibre Channel networks.
    3. Network complexity: Implementing and managing iSCSI networks may require additional networking knowledge and expertise compared to Fibre Channel.
    4. Security concerns: While iSCSI supports data encryption and authentication, it is still vulnerable to network-based attacks if not properly secured.
    5. Resource utilization: Since iSCSI uses the server's CPU and network bandwidth for data transmission, it may impact overall server performance and resource utilization.

    Overall, iSCSI offers a cost-effective and flexible storage networking solution, especially for small to medium-sized businesses. However, it may not be suitable for high-performance or latency-sensitive environments that require dedicated Fibre Channel networks.
