The ABCs of Storage Area Networks
Making the decision to invest in storage area networks (SANs) requires an understanding of the differences between various approaches to managing storage. Unfortunately, the differences are not always clearly understood outside the realm of the enterprise data center. SANs, network-attached storage (NAS), and direct-attached storage (DAS) are sometimes positioned as competing technologies, but in actuality all three are found in today's enterprise IT environments and have distinct applications. This Research Byte provides a primer on these three types of storage management systems and their application.
Storage Area Networks Support Consolidation
Storage areas networks are rapidly increasing in numbers in organizations both large and small. A major reason for SAN popularity is their history of providing positive economic results. Storage consolidation using SANs pays off by reducing the administrative and maintenance effort necessary to support pools of network attached storage devices or other types of distributed storage.

Standardization Boosts iSCSI Economic Potential (2Q03)
The advent of the Internet SCSI standard holds the potential for reducing cost of ownership of SANs. The iSCSI standard marries IP, SCSI, and Gigabit Ethernet technologies to provide a high-speed data path that removes many of the bottlenecks of traditional TCP/IP data transfers. Even though SANs are relatively new technology, they have become widely used. The 2003 Computer Economics Information Systems Spending survey indicates that half of IT sites either are using or implementing SANs.
