Furthermore, most organisations have a storage requirement in so far as they need to retain documents, files and other types of information and to be able to let it be accessed among the users of the computer network. These make sure that storage devices such as disks, tape drives etc. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols. To the user, Storage Area Networks appear to be local to the operating system, but they are actually remote. This leads to a better performance overall as the data is not affected by local traffic or bottlenecks. Even the most complex technologies provide the most basic of functions. Storage technologies and capabilities include Direct-attached storage, JBOD, network-attached storage, storage area networks, SCSI, iSCSI, and Fibre Channel. Storage-area networks (SANs) established their role as the heart of enterprise-level primary storage in the early 2000s. In DAS, the data is directly attached to one server. If the operating system and/or programs knows the storage is not local, you are probably working with a NAS. Your data flow is only as fast as your network connectivity allows. Thus, a Storage Area Network (SAN) is a network that interconnects and provides a shared pool of storage devices to multiple servers. FCoE makes it possible to move Fibre Channel traffic across existing high-speed Ethernet infrastructure and converges storage and IP … 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. Product / Technical Support. The storage data is very secure on the storage area network and cannot be copied or stolen by anyone else. The storage pool is controlled by administrators that assign logical unit numbers (LUNs), or blocks of storage capacity. In addition to communicating between storage devices and computer… Why Storage Area Networks? A SAN reorganises storage resources in an into an independent and high-performance network. Storage area networks and network-attached storage provide networked storage solutions. Why, and how, can we use a storage area network?

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. This means that information is potentially stored across a wide range of servers or other means of storage, and as a result it can be difficult to access information, simply because it is not in a single place. The storage is removed from the purview of the system and moved and moved onto a separate network. Similar to a file server, a NAS array is a standalone device that connects to a network and provides file-level storage that can be accessed by end users. In some configurations a SAN is also connected to the network. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.

Cisco MDS 9148 Multilayer Fabric Switch. There can be a remote copy of the storage data kept separately using the storage area network. Using a SAN solves both issues and maintains read/write speed. SAN storage, then, is a high-speed network that provides network access to storage. A SAN, on the other hand, presents storage devices to a host such that the storage appears to be locally attached. The only difference between regular fiber optic computer networks such as the Internet and a fiber optic storage area network such as a SAN is how the devices talk to each other over the network. More importantly, it should be seen as a knowledge repository, in that it saves people replicating and researching, for example, a project when perhaps someone in the organisation has already created a similar report or a similar level of expertise. SAN's use special switches as a mechanism to connect the devices. SANs are primarily used to access storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage. SAN is the shortened form for “ storage area network ”, which is basically a much secured network of speedy data transfers, providing complete access to fused block-level data storage. High-end enterprise SANs may also include SAN directors for higher performance and efficient capacity usage.
