SAN Basics: What You Need to Know About Storage Area Networks

by frankd228801

Do you run a business that relies on storing data? If so, you need to know about SAN storage. SAN, which stands for Storage Area Network, is a type of storage system that connects multiple computers and provides access to stored data. In this blog post, we will discuss the basics of SAN storage and provide tips on how to choose the right SAN for your business.

The Basics of SAN Storage

SAN storage systems are composed of three main components:

– SAN controllers: SAN controllers are responsible for managing the SAN and providing access to stored data.

– SAN switches: SAN switches connect the SAN controllers to the computers that need access to the stored data.

– Storage devices: Storage devices, such as hard drives or solid state drives, actually store the data.

SAN storage systems can be either Fibre Channel SANs or iSCSI SANs. Fibre Channel SANs use a special type of cable, called fibre optic cable, to connect the SAN components. iSCSI SANs use standard Ethernet cables to connect the SAN components.

SAN Storage Benefits

SAN storage offers many benefits for businesses that need to store data. SANs are scalable, meaning they can grow as your business’s needs grow. SANs are also highly available, meaning that data is always accessible and there is no single point of failure. SANs are also easy to manage, because all of the data is stored in one central location.

How to Choose a SAN

When choosing a SAN for your business, there are several factors to consider. First, you need to decide whether you want a Fibre Channel SAN or an iSCSI SAN. If you already have Ethernet cables in your office, then an iSCSI SAN may be the best option for you. If you are starting from scratch, then a Fibre Channel SAN may be the better option.

Another factor to consider is your budget. Fibre Channel SANs tend to be more expensive than iSCSI SANs. However, Fibre Channel SANs offer higher performance and greater security.

Finally, you need to decide how much storage you need. SANs are available in a variety of storage capacities, so you can choose the SAN that best meets your business’s needs.


If you are looking for a reliable and scalable storage solution for your business, then Storage Area Network may be the right choice for you. SANs offer many benefits, including high availability and easy management. When choosing a SAN, be sure to consider your budget and storage needs. With the right SAN, you can keep your business’s data safe and accessible.
