Using ESXi with iSCSI SAN

ESXi can connect to external SAN storage using the Internet SCSI (iSCSI) protocol. In addition to traditional iSCSI, ESXi also supports iSCSI Extensions for RDMA (iSER).

When the iSER protocol is enabled, the host can use the same iSCSI framework, but replaces the TCP/IP transport with the Remote Direct Memory Access (RDMA) transport.
