iSNS: Technical overview of discovery in IP SANs

The three main protocols for IP SANs are Fibre Channel over IP (FCIP), Internet Fibre Channel Protocol (iFCP), and Internet SCSI (iSCSI). As shown in Figure 1, the iSCSI, iFCP, and FCIP protocols support a serial SCSI-3 interface to the standard SCSI command set expected by the operating system and upper-layer applications. This allows conventional storage I/O to be performed over a high-performance gigabit transport. Serial SCSI-3 transactions are carried over TCP/IP, although only iFCP and iSCSI leverage native TCP/IP for each storage end device. Each IP storage protocol has unique requirements for discovery.

iSCSI is also supported as the ideal alternative to SAN solution for business. Affordable and cost-effective iSCSI allows large scale business to consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks. With the iSCSI support, DS1812+ provides a seamless storage solution for virtualization servers, such as VMware, Citrix, and Hyper-V.
