Using ESXi with iSCSI SAN 10
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.
About iSCSI SAN
iSCSI SANs use Ethernet connections between hosts and high-performance storage subsystems.
On the host side, the iSCSI SAN components include iSCSI host bus adapters (HBAs) or Network
Interface Cards (NICs). The iSCSI network also includes switches and routers that transport the storage
traffic, cables, storage processors (SPs), and storage disk systems.
