With the ever-increasing need for businesses and organizations to maintain and manage large amounts of data, storage issues have become a concern and an investment priority. Organizations and business must have a good understanding of the features and characteristics of network storage in order to design and implement a network storage system that addresses their present and future needs. This paper will define and compare the storage area networks (SAN) with network-attached storage (NAS) as well as a historical perspective of directly-attached storage (DAS). Some of the benefits associated with establishing a network storage system will also be identified. This paper will identify some of the general characteristics of SAN architecture and protocols, such as Fibre Channel and iSCSI. Another area addressed will be management software issues and its critical role as part of successful SAN deployment. Not only must data be reliable and available at all times, data must also be kept confidential and protected. While the data is being transmitted over the network, security is also a concern that must be addressed.
