Host Configuration
This chapter describes host protocol concepts and the details of host configuration. The
HOST CONFIGURATION
function menu provides submenus of
Overview,
iSCSI Ports
, and
Fibre Channel Ports
.
TIP:
The
Fibre Channel Ports
function menu will appear only when the system
has a fibre channel host card installed.

Host Protocol Technology
This section describes the host protocol technology of iSCSI (Internet SCSI) and fibre
channel.
7.1.1.
iSCSI Technology
iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System
Interface) commands and data in TCP/IP packets for linking storage devices with servers
over common IP infrastructures. iSCSI provides high performance SANs over standard IP
networks like LAN, WAN or the Internet.
IP SANs are true SANs (Storage Area Networks) which allow several servers to attach to an
infinite number of storage volumes by using iSCSI over TCP/IP networks. IP SANs can scale
the storage capacity with any type and brand of storage system. In addition, it can be used
by any type of network (Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet)
and combination of operating systems (Microsoft Windows, Linux, Solaris, Mac, etc.) within
the SAN network. IP-SANs also include mechanisms for security, data replication, multi-path
and high availability.
Storage protocols, such as iSCSI, have “two ends” in the connection. These ends are initiator
and target. In iSCSI, we call them iSCSI initiator and iSCSI target. The iSCSI initiator requests
or initiates any iSCSI communication. It requests all SCSI operations like read or write. An
initiator is usually located on the host side (either an iSCSI HBA or iSCSI SW initiator).
