Storage area networks were developed in order to overcome some of the problems associated with network attached storage (NAS). This is because NAS devices are sometimes difficult to manage and do not have the same storage capacity. An issue with network attached storage is that because of their design, and because of the way in which information is passed across a network, the network can be slow due to the increased amount of traffic that is created by the NAS.
As a result many analysts forecast that storage area networks will become predominant in the storage market.
That said, the whole area of storage is complex and the systems available will very much rely upon your organisations’ needs, plans for growth and, ultimately, budget.
