A storage area network (SAN) is any high-efficiency network whose primary goal is to allow storage devices to communicate with pc systems and with every other. This architecture actually isn’t much various than it would be if the file server were working with direct attached storage. The storage guys are partnering with the network and server guys to produce the data center developing blocks of the future. The network is made use of to move data among the several storage devices, allows sharing data between unique network servers, and offers a rapidly connection medium for data backup and restoration and information archiving and retrieval. SCSI technologies uses parallel cabling which severely limits speed, distance and the quantity of attached storage devices.
It remains to be seen regardless of whether these developments are in the end a good thing for the storage guys, as the folks who make each servers and storage may possibly have a leg up in giving standardized options with one help point of view.
The smarter information center with the enhanced economics of IT can be accomplished by connecting servers and storage with a higher-speed and intelligent network fabric. A unified SAN takes this idea a step further by exposing not only dedicated logical unit numbers ( LUNs ) – like any other SAN – but file method-based, NAS-like storage. NAS devices will continue to perform their precise functions but shall migrate, more than time, to the Storage Area Network model. Before the advent of SANs, organizations frequently utilized direct-attached storage (DAS).
This reduces the excess capacity essential for every single server, enables administrators to centralize storage management, and enables storage sources to be swiftly reallocated to various servers. The file server is connected to the SAN in a way that makes it possible for the storage … Read More
