How to recover data from NAS Promise VTrak E5320f

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 Promise 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 differ from other storage protocols?

    iSCSI (Internet Small Computer System Interface) is a storage protocol that allows the transmission of SCSI commands over IP networks. It enables the use of IP networks to connect storage devices, such as disk arrays, tape libraries, and virtual tape libraries, to servers.

    The main difference between iSCSI and other storage protocols lies in the way they transport data. Here are a few comparisons:

    1. Fibre Channel (FC): FC is a dedicated storage networking protocol that uses fiber optic cables for high-speed data transfer. It requires specialized hardware and switches, making it more expensive and complex to implement compared to iSCSI. On the other hand, iSCSI uses existing Ethernet infrastructure, making it more cost-effective and easier to manage.
    2. Network-Attached Storage (NAS): NAS is a file-level storage protocol that allows file sharing over a network. It is suitable for general-purpose file serving and does not provide block-level access like iSCSI. iSCSI, on the other hand, provides block-level access, allowing servers to access storage devices as if they were directly attached.
    3. Direct-Attached Storage (DAS): DAS is a storage configuration where storage devices are directly connected to servers. It is a simple and low-latency solution but lacks flexibility and scalability. iSCSI, being a network-based storage protocol, allows for centralized storage management, easier scalability, and the ability to share storage resources among multiple servers.
    4. Internet Fibre Channel Protocol (iFCP): iFCP is a protocol that encapsulates Fibre Channel frames into IP packets, similar to iSCSI. However, iFCP requires specialized gateways to convert between IP and Fibre Channel, while iSCSI operates natively over IP networks.

    In summary, iSCSI is a cost-effective, flexible, and scalable storage protocol that leverages existing IP networks for block-level storage access. It differs from other protocols like Fibre Channel, NAS, and DAS in terms of infrastructure requirements, access methods, and scalability.

  • How does iSCSI work in a network storage environment?

    iSCSI (Internet Small Computer System Interface) is a protocol that allows SCSI commands to be transmitted over a network, enabling remote access to storage devices. In a network storage environment, iSCSI works as follows:

    1. Initiator: The device or computer that initiates the iSCSI connection is called the initiator. It could be a server, workstation, or any device that requires access to the storage.
    2. Target: The storage device or system that provides the storage resources and responds to the iSCSI commands is called the target. It could be a physical storage array, a virtual storage system, or even a software-based storage solution.
    3. Network: The initiator and target communicate over a TCP/IP network, typically using Ethernet as the underlying transport. The network can be a local area network (LAN) or a wide area network (WAN).
    4. iSCSI Session: To establish a connection, the initiator sends an iSCSI login request to the target. If the target accepts the request, an iSCSI session is established between the initiator and target. This session represents a logical connection over which SCSI commands and data can be exchanged.
    5. SCSI Commands: Once the session is established, the initiator can send SCSI commands to the target. These commands include read, write, inquiry, and various other storage-related operations. The iSCSI protocol encapsulates these SCSI commands into TCP/IP packets for transmission over the network.
    6. Data Transfer: When the target receives a SCSI command, it processes the request and performs the necessary storage operations. The target then sends the response, along with any requested data, back to the initiator over the iSCSI session. The data transfer occurs over the TCP/IP network, ensuring reliable and ordered delivery.
    7. Storage Access: The initiator treats the remote storage accessed via iSCSI as if it were directly attached to the local system. It can mount the storage, format it, create file systems, and use it for various applications or services, just like any other locally attached storage device.

    Overall, iSCSI provides a cost-effective and flexible way to extend storage resources over a network, enabling centralized storage management and remote access to storage devices.

  • Does the NAS Promise VTrak E5320f support iSCSI protocol, and if so, what are the benefits and limitations of using iSCSI with this NAS system?

    Yes, the NAS Promise VTrak E5320f does support the iSCSI protocol.

    Benefits of using iSCSI with this NAS system:

    1. Flexibility: iSCSI allows for the creation of virtual disks that can be accessed over a network, providing flexibility in storage allocation and management.
    2. Cost-effective: iSCSI utilizes existing Ethernet infrastructure, eliminating the need for dedicated Fibre Channel networks. This can result in cost savings compared to traditional SAN solutions.
    3. Scalability: iSCSI supports the use of multiple initiators and targets, allowing for easy expansion of storage capacity as needed.
    4. Compatibility: iSCSI is compatible with various operating systems and can be used with both physical and virtual servers, making it a versatile storage solution.

    Limitations of using iSCSI with this NAS system:

    1. Performance: While iSCSI can offer good performance, it may not match the high-speed capabilities of dedicated Fibre Channel networks in certain scenarios.
    2. Network Dependency: Since iSCSI relies on Ethernet infrastructure, the performance and stability of the storage system can be affected by network congestion or failures.
    3. Security: Although iSCSI supports authentication and encryption, it may not provide the same level of security as dedicated storage protocols like Fibre Channel.

    It is important to consider these factors when deciding whether to use iSCSI with the NAS Promise VTrak E5320f, based on your specific storage requirements and infrastructure capabilities.
