The Basics of iSCSI Cable: What You Need to Know for SAN Storage

When it comes to storage area networks (SANs), there are various options available for connecting storage devices to servers. One of the most popular methods is using iSCSI cables, which allow for remote connections between devices over a network.

In this document, we will delve into the basics of iSCSI cables, exploring what they are, how they work, and why they are a preferred choice for SAN storage. By the end, you will have a better understanding of iSCSI cables and their role in modern data storage solutions. So let’s get started!

What is iSCSI?

iSCSI stands for Internet Small Computer System Interface. It is a protocol used for transmitting SCSI commands over an IP network. In simpler terms, iSCSI allows for block-level access to storage devices over a network. This enables remote data storage and retrieval.

But why use iSCSI instead of traditional methods like Fibre Channel (FC)? The answer lies in its cost-effectiveness and flexibility.

How Does iSCSI Work?

iSCSI operates by encapsulating SCSI commands and data into IP packets. These are then transmitted over standard Ethernet networks. This allows for the use of existing network infrastructure. This reduces the need for additional hardware and cabling.

At the core of iSCSI is the target and initiator relationship. The storage device acts as the target, while the server or workstation acts as the initiator. The target presents its storage resources as logical units (LUNs), which can then be accessed and managed by the initiator.

Why Use iSCSI for SAN Storage?

There are several reasons why iSCSI is a preferred choice for SAN storage:


As mentioned earlier, iSCSI utilizes the existing network infrastructure. This enables the storage and retrieval of data over IP networks. This eliminates the need for specialized hardware and cablin. These are typically required by other storage area network (SAN) solutions like Fibre Channel (FC).

By leveraging TCP/IP protocols, iSCSI provides a cost-effective option for organizations. This is to put in place storage solutions. It happens without the additional overhead and complexity associated with dedicated FC networks.


It is a versatile storage networking protocol. It offers compatibility with both IP networks and Fibre Channel. This provides organizations with the flexibility to choose the network that best suits their specific requirements and infrastructure.

This adaptability ensures seamless integration and optimal performance. It empowers organizations to efficiently manage and access their data with ease.

Remote Access

It is also a powerful technology that facilitates remote data storage and retrieval. iSCSI configuration has become a go-to solution. This is for disaster recovery and offsite backups. This is with its ability to seamlessly connect and transfer data over IP networks.

By leveraging this technology, organizations can ensure the safety and availability of their critical data, even in the face of unforeseen circumstances. With SAN Storage prices worth your money, you can be sure your data are in safe hands.
