How iSCSI is implemented on the host

iSCSI can be implemented on the host using hardware or software.

You can implement iSCSI in one of the following ways:

  • Using Initiator software that uses the host’s standard Ethernet interfaces.

  • Through an iSCSI host bus adapter (HBA): An iSCSI HBA appears to the host operating system as a SCSI disk adapter with local disks.

  • Using a TCP Offload Engine (TOE) adapter that offloads TCP/IP processing.

    The iSCSI protocol processing is still performed by host software.
