Chapter 1 Before Configuring SN 5428-2 Storage Router Software
Transparent SCSI Routing Overview
to it, with each host having a WWPN. Table 1-5 shows the correlation between the IP hosts, the Gigabit
Ethernet IP address of the SCSI routing instance, storage device mapping, and IP-host-to-FC-address
(WWPN) mapping.
Note The purpose of Figure 1-13 and Table 1-5 is only to illustrate the concept of storage mapping, FC
address mapping, and access control. The IP addresses and WWPNs will vary according to each site. In
addition, the figure and the table exclude any additional SN 5428-2 Storage Routers that could be
configured for multiple paths between hosts and storage devices.
