Network types

Most storage networks use the SCSI protocol for communication between servers and disk drive devices. They do not use SCSI low-level physical interface (e.g. cables), however, as its bus topology is unsuitable for networking. A mapping layer to other low-level protocols is used to form a network:

* ATA over Ethernet (AoE), mapping of ATA over Ethernet,
* Fibre Channel Protocol (FCP), the most prominent one, is mapping of SCSI over Fibre Channel (FC),
* Fibre Channel over Ethernet (FCoE),
* mapping of FICON over FC, used by mainframe computers,
* HyperSCSI, mapping of SCSI over Ethernet,
* iFCP[1] or SANoIP[2] mapping of FCP over IP.
* iSCSI Extensions for RDMA (iSER), mapping of iSCSI over InfiniBand (IB),
* iSCSI, mapping of SCSI over TCP/IP
