Layman’s Guide to Understanding SAN Storage Terminology

Welcome to the Layman’s Guide to Understanding SAN Terminology. In this guide, we will explain some of the basic terminology used in Storage Area Networks (SANs), a type of computer network that connects servers and storage devices. We’ll also discuss common uses for SANs and ways they can be deployed in businesses. By the end of this guide, you should have a clear understanding of the basics of SAN terminology and applications. So let’s get started!

What does SAN Stand for?

SAN stands for Storage Area Network and is a high-speed communication method that allows multiple devices to access the same data at the same time. It is used by large organizations to provide fast, secure access to data stored on servers.

SAN Storage Technology

SANs use two major types of technology: Fibre Channel (FC) and IP SANs. FC SANs use dedicated optical cables to connect devices and are typically used for mission-critical applications due to their high performance and reliability. IP SANs, on the other hand, use standard Ethernet cabling to connect multiple devices over a single network. They are more cost effective but lack the same level of performance as FC SANs.

SAN Connectivity

In order to communicate with one another, SANs use a number of different protocols. Commonly used protocols include SCSI (Small Computer System Interface) and iSCSI (Internet SCSI), which are both used for sending data over networks. Additionally, FC SANs use the FC protocol in order to move data quickly and reliably over dedicated optical cables.

SAN Storage Benefits

One of the main benefits of SANs is their scalability, as they can be expanded or contracted depending on the needs of an organization. This helps to reduce costs and ensure that data is always available when needed. Additionally, SANs provide a high level of redundancy and reliability, making them well suited for mission-critical applications.

Finally, SANs are designed with security in mind and offer a number of features to protect data from unauthorized access or corruption. They can also help organizations meet various compliance requirements.

Conclusion

In conclusion, understanding the terminology used in Storage Area Networks (SANs) is essential for those wanting to utilize this powerful technology. By using dedicated optical cabling and protocols such as SCSI and iSCSI, SAN solutions provide businesses with a fast, secure, and reliable storage solution. Additionally, they offer scalability, redundancy and security benefits that make them an ideal choice for mission-critical applications. We hope this guide has been useful in introducing you to the basics of SAN terminology.
