3: I/O Techniques > 3.5 IP STORAGE

3.5 IP STORAGE

Fibre Channel SANs are being successfully implemented in production environments. Nevertheless, a transmission technology is desired that is suitable for both storage traffic (SCSI) and LAN (TCP/IP). IP storage is an approach to build storage networks upon TCP, IP and Ethernet.

This section first introduces various protocols for the transmission of storage data traffic via TCP/IP (Section 3.5.1). Then we explain to what extent TCP/IP and Ethernet are suitable transmission techniques for storage networks at all (Section 3.5.2). Finally, we discuss a migration path from SCSI and Fibre Channel to IP storage (Section 3.5.3).

3.5.1 IP storage standards: iSCSI, iFCP, mFCP, FCIP and iSNS

Three protocols are available for transmitting storage data traffic over TCP/IP: iSCSI, Internet FCP (iFCP) and Fibre Channel over IP (FCIP) – not to be confused with IPFC (Section 3.3.8). They form the family of IP-based storage protocols that are also known as IP storage. These standards have in common that in one form or another they transmit SCSI over IP and thus in practice usually over Ethernet. Of all IP-based storage protocols iSCSI and FCIP are most relevant.
