Storage Array Network SAN

What Is A Storage Area Network (SAN) And How Does It Work

In very simple terms, a storage area network is a special type of network that enables you to connect multiple servers to a common shared storage device. SANs are quite different from other storage networks like DAS because they provide specialized and dedicated network infrastructure for better storage connectivity.

Enterprise SAN storage solutions incorporate various technologies for better connectivity such as Fibre Channel SAN and iSCSI SAN. These connection techs help to establish strong connections between servers and storage devices. To sum up the entire structural architecture, we can state that almost all of the SAN solutions contain the following devices, servers, storage arrays, SAN switches, SAN fabric, and management software.

Different Types of Storage Array Network Devices

SAN devices are different from other network storage devices because they are available in both physical and virtual forms. Let’s discuss both of these types briefly.

Physical SAN Devices: They are the old type of storage devices and can be defined as disk arrays that are connected to a fibre channel SAN or an ethernet. Physical SAN provides very high-performance levels and scalability options, however, they are more expensive.

Virtual SAN Devices: They offer almost the same performance and scalability as physical SAN and have much lower prices. Virtual SAN is created by installing network software on the server.

Applications of High-performance SAN

SAN is a very useful technology and it can be used in a wide range of applications, like the following:

Data Centers: The storage array network is widely used in large data centres to provide shared access to multiple servers at a time.

Virtual Environments: SAN devices also play a very crucial role in the virtualization of different environments. They allow the virtual machines to access the data in storage devices more efficiently and also provide better flexibility.

Database Management: High-performance SAN provides fast speeds for data transfers. This fast speed ensures swift data transactions which makes them perfect for data warehouses.
