Storage Area Network (SAN) is a dedicated data storage network that helps one to access the block level data. This network technology is ideally applied in the fabrication of SAN Storage Devices including optical jukeboxes, disk arrays and tape libraries, which are connected and accessible to the servers and in turn they make an illusion to the operating system of being connected locally. However, the internal storage network of a typical SAN network is not accessible to the LAN of any other connected devices. Due to the decrease in cost and most importantly with the advent of better technology, the fall in complexity of the SAN devices, many small, big and enterprise organizations adopted this storage network technology which resulted in an allover increase in wider market business scope of the SAN.
Use of SAN Storage Devices bears a number of benefits fitting this technology with the operations of a number of organizations. First of all, sharing of storage and virtual existence of storage devices simplifies storage administration. One doesn’t need to physically deallocate the storage devices and their associated peripherals including the cables and other cooling devices from one server to another. This added flexibility is needed in the operations of large enterprises. Another benefit is that the server can be directly booted using SAN directly. This facility is new, many opine it to be the future concept of data center designing. SAN also provides stronger tendency to handle disaster recovery mechanisms. Above all the economic advantage achieved after 2000, has also brought about a new benefit in using SAN devices.
SAN typically works in the fiber channel fabric topology. Fabric refers to network segments. Of late, most of the SAN equipment vendors provide fiber channel routing mechanisms. This mechanism enables the devices to send or cross data between the fibers without combining them with an overall increase in scalability of the SAN architecture. The routing and mapping mechanism is often enabled over IP or SONET/SDH for proper traffic control through the fibers.
The media and entertainment industry, especially the video editing companies need very high speed data transfer rates with a nominally low latency. For these work groups, SAN Storage Devices prove to be very useful, often more beneficial than the enterprise organizations. These SANs are often known as serverless SANs, since the video workflow clients who are involved in ingest, editing and playout of the video files directly connect to the SANs rather than the servers. The distributed file systems control the data flow or the data traffic through the fibers.
