    A Storage Area Network (SAN) is a specialized, high-speed network that provides block-level network access to storage. 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.

    SANs are commonly based on Fibre Channel (FC) technology that utilizes the Fibre Channel Protocol (FCP) for open systems and proprietary variants for mainframes. 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 on...

    SAN storage has been around for many years. But several factors are making this network-based storage solution more important than ever for everyday business use. For example: 1. Organizations need to provide users reliable access to data at all times. 2. Data of all types, structured and unstructured, is growing exponentially. 3. Cloud computing, ...

    SANs provide any-to-any connectivity for servers and storage devices using Fibre Channel (FC) switches that are compatible with the FC protocol. FC SAN switches are used to connect devices within a SAN to create the SAN fabric. Routers, gateway devices, and cables that help the SAN interconnect servers with storage devices are also part of SAN fabr...

    A SAN and network-attached storage (NAS) are both network-based storage solutions; however, a SAN is more complex. A SAN is a network that operates independently of an organization's operating system and is comprised of many different storage devices. It uses FC switches and stores data at the block level. To a client operating system, the SAN typi...

    It doesn't have to be. If an organization already has the right SAN infrastructure in place, it can work with a leading provider of SAN technology to modernize its storage area network seamlessly and quickly, and without a major equipment upgrade. The business can also invest in today's SAN technology that can evolve to keep up with increasing appl...

  2. Storage area networks (SANs) are the most common storage networking architecture used by enterprises for business-critical applications that need to deliver high throughput and low latency.

  3. A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers. The availability and accessibility of storage are critical concerns for enterprise computing.

  4. SAN is an acronym for storage area network. SANs consolidate storage in a single storage area separated from the local area network (LAN). Computers and devices connected to the SAN have access to storage devices like tape libraries and disk arrays available on the SAN servers as though it is local storage. How does SAN storage work?
