Transparent SCSI Routing Overview

to it, with each host having a WWPN. Table 1-5shows 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 1-13and Table 1-5is 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.

SN 5428-2 presents IP hosts as

FC hosts with WWPNs:

IP host A = WWPN 201000023D000100 IP host B = WWPN 201000023D000101 IP host C = WWPN 201000023D000102

WWPN 3100112233445566

and its LUNs accessible by IP host A

WWPN 3100112233445577

and its LUNs accessible by IP host B

WWPN 3100112233445588

and its LUNs accessible by IP host C
