Storage area networks basics pdf

Fig1: a tiered overview of storage area network. The storage area networks create modern techniques of attaching storage to servers and these modern techniques enhance availability and performance. These networks are availed to bypass networks like traditional network bottlenecks.

Storage area network furnishes the facility of direct information transfer and information transfer with a high speed between servers and storage machines in the below mentioned ways:.

Availing a storage area network gives following advantages:. Fiber channel based components of SAN storage area network are:. We need to use a storage area network to overcome the problems and difficulties that we are facing today and also because of requirements and necessities which the present storage infrastructures should meet. Those are:. Advantages which might bring a SAN to an infrastructure of a high data dependent business are summarized in three simple concepts and they are:.

LinkedIn RSS. United States. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols. SANs may also span multiple sites. A SAN presents storage devices to a host such that the storage appears to be locally attached. This simplified presentation of storage to a host is accomplished through the use of different types of virtualization.

In addition, the use of Fibre Channel over Ethernet FCoE makes it possible to move FC traffic across existing high speed Ethernet infrastructures and converge storage and IP protocols onto a single cable. Other technologies like Internet Small Computing System Interface iSCSI , commonly used in small and medium sized organizations as a less expensive alternative to FC, and InfiniBand , commonly used in high performance computing environments, can also be used.

In addition, it is possible to use gateways to move data between different SAN technologies. SNIA is a worldwide source for vendor neutral training and education on Storage and Information Management technologies and provides an independent understanding of a broad range of Storage and Information Management technologies from basic foundations to advanced techniques.
