A SAN is a Storage Area Network. SANs have been the “gold standard” for high performance storage solutions for many years. Their advantages include a dedicated high performance network that only carries data traffic, thus offering improved access to data. While this dedicated network improves storage performance, it comes at increased cost of both hardware and personnel. Specialized network cards and cabling and additional training are required for SAN implementation and management. This cost delta has put SANs beyond the reach of most small businesses. However, continual improvements in Ethernet network speeds from 10 to 100 and now 1000 megabit (soon 10 gigabit networks will become common place) has brought a shift from the traditional SAN with its dedicated network to the iSCSI SAN which runs SCSI command sets over internet protocol. iSCSI SANs run over “standard Ethernet” and thus are simpler to manage and less costly to implement, since they run internet protocol, they can also be accessed over the internet, eliminating the cable length limitations of the traditional SAN. As Ethernet speeds increase, the performance benefit of a dedicated SAN network over an iSCSI SAN is diminished so the future of storage area networks largely belongs to iSCSI.
