Document Summary
Itm 301 network equipment in commercial. Fault tolerance - techniques that allow data storage or other operations to continue in the event of a failure or fault of one its components. A nas device cannot communicate directly with clients: clients go through a file server, which communicates with the nas device o. A san is a network of storage devices that communicate directly with each other and with other networks: uses a type of architecture that is similar to mesh topology, which is very fault- tolerant. Sans use one of two types of transport layer protocols: fibre channel (fc, iscsi n. A san can be installed in a location separate from the lan it serves. Sans are highly scalable and have: a very high fault tolerance, massive storage capabilities, fast data access. Sans are best suited to environments with huge quantities of data that must always be quickly available.
