System Configuration Using an IP-SAN
In an IP-SAN, LAN cables are used to connect hosts to storage systems. The
cable port on the host is called an iSCSI host bus adapter (iSCSI HBA) or a
network interface card (NIC). In order to use an NIC, the iSCSI software
must be installed ahead of time on the host. The cable port on the storage
system is called a port (P) on a channel adapter (CHA) used for iSCSI
connections.
A logical unit (LU), which lies in a storage system, is either an input target or
an output target to or from a host. The areas within an LU are called Devs.
A route that connects a host to a Dev in an LU is called a path.
HDLM assigns a unique ID to each management-target path. This ID is called
AutoPATH_ID. Sometimes, the path is also just simply called a management
target.
Figure 2-2 Configuration of an IP-SAN System When Using an iSCSI HBA on
page 2-5 shows the configuration of an IP-SAN system when using an
iSCSI HBA. Figure 2-3 Configuration of an IP-SAN System When Using iSCSI
Software and an NIC on page 2-6 shows the configuration of an IP-SAN
system when using the iSCSI software and an NIC.
