Supported platforms for iSCSI
The iSCSI target gateway service is supported on the Brocade 48000 director with CP blades
running Fabric OS v5.2.0 and later releases, and configured with an FC4-16IP blade.
Common iSCSI Target Gateway Admin functions
You can right-click on the table content in the window to access Export, Copy, and Search options:
NOTE
You must accept the Brocade Certificate at the beginning of the login to Web Tools to enable the
functionality of Export and Copy.
• Click Export Row or Export Table to save the contents to a tab-delimited file. For CHAP, the
secret is still encrypted.
• Click Copy Row or Copy Table to copy the contents in tab-delimited text format to a file.
• Click Search to search for a specific text string in the table.
Enter a text string in the box that displays in the table and press Enter. This is an incremental
search and allows 24 maximum characters including the wildcard characters: question mark
(?) and asterisk (*). The first row containing the text string is highlighted. To find the next
match, press the down arrow. To find the previous match, press the up arrow.
If the text is not found in the table, the text displays in red color.
Terminology
iSCSI target gateway services require you to understand some additional terminology. Table 17
shows the terms that are used in this document to explain how the iSCSI target gateway is
implemented.
TABLE 17 iSCSI target gateway services terminology
Term Definition
iSCSI Internet-SCSI. A transport carrier of the SCSI protocol over IP.
iSCSI target gateway An intermediate device in the network that allows the iSCSI initiators in an IP SAN to
access and utilize storage in a Fibre Channel SAN. the FC4-16IP AP blade in a
Brocade 48000 director functions as an iSCSI target gateway.
iSCSI port A special GbE port used for iSCSI only. A Fibre Channel virtual initiator is created
behind each iSCSI port running as a proxy Fibre Channel initiator.
iSCSI virtual target A unique target device in the IP SAN that contains LUNs from the real Fibre Channel
targets and is identified by an IQN.
iSCSI initiator A device that begins an iSCSI transaction by issuing a command to another device
(the iSCSI target), giving it a task to perform. Typically, an iSCSI host adapter is the
initiator but targets can also become initiators.
iSCSI session An iSCSI session is the basic communication “pipe” from an iSCSI initiator to an
iSCSI target. A session is a group of TCP/IP connections that link an initiator with a
target (loosely equivalent to a SCSI I-T nexus).
