A storage area network is a high-speed data transfer network<\/strong> that provides access to physically and logically centralized data. A SAN typically consists of one or more storage devices connected to one or more servers. <\/p>\n\n\n\n The server can be connected to the SAN directly or through a network switch<\/strong>. This article will cover everything you need to know about SAN, how it works, and its pros and cons. <\/p>\n\n\n\n A storage area network is a group of storage devices and computers<\/strong>. They are connected via high-speed optical connection, so the data can be shared quickly.<\/p>\n\n\n\n This high-speed network is made up of switches transmitting data using a fibre channel protocol<\/strong>. It also includes optical fiber cables. SAN is unique because it uses a network to create a shared pool of storage devices. <\/p>\n\n\n\n This network moves the data through different storage devices, which can be shared between the network servers, making quick connections for data backup possible. With it, data archiving, retrieval and restoration can be done quickly<\/strong>. <\/p>\n\n\n\n Although the many devices of SAN are typically placed in one room, one of the perks of this network is that they can be located in different locations and connected even at long distances. <\/p>\n\n\n\n A SAN is a dedicated high-speed network that provides block-level storage access to servers<\/strong>. A SAN typically uses a storage controller that connects to the server over a high-speed channel (such as a 4 Gbps Fibre Channel or 10 Gbps Ethernet). <\/p>\n\n\n\n The controller presents the storage devices (such as hard drives or solid-state drives) to the server as logical units. Or, more precisely, it gives each such disk a unique logical unit number. <\/p>\n\n\n\n SAN is made of communication infrastructure, which allows any-to-any device connection within the network via interconnected elements<\/strong>, such as director switches. The SAN network provides physical connections and can be considered an extension of the bus concept. <\/p>\n\n\n\n This technology has come a long way, and new methods for attaching storage to servers are being developed all the time.<\/p>\n\n\n\n A SAN protocol determines how switches and devices communicate within a storage area network. These are the most common protocol types: <\/p>\n\n\n\nThe Definition of Storage Area Networks <\/h2>\n\n\n\n
