7 – SANsurfer iSCSI/FC Router Manager System Tree Window

„Target TCP Port Number – Identifies the TCP port number the iSR-6140 uses to receive iSCSI target commands. The iSCSI community uses TCP port number 3260 by default. Any change to this TCP port number requires a corresponding change in all iSCSI initiators connecting to this iSCSI target port.

„Jumbo Frame – Enables or disables iSR-6140 jumbo frame size as the maximum transfer unit (MTU). Disabling this option sets the port to support 1500 byte MTU. Enabling this option sets the port to support 9000 bytes MTU. To change this setting, select Enabled or Disabled from the drop-down list box.

NOTE:

An MTU size greater than 1500 should only be used when the router is connected to a 1000 Mbps Ethernet network.

„Max Burst Length – Displays the iSCSI maximum burst length, which may range between 512 to 262144 bytes, depending on iSCSI port configuration.

„Max First Burst Length – Displays the iSCSI maximum first burst length, which may range between 512 to 262144 bytes, depending on the iSCSI port configuration.

„Security Settings – This section provides the following parameters:

„Enable Header Digest – Enables or disables support for iSCSI header digest. Header digest is an ISCSI feature where a validity check field is added to iSCSI PDU headers to verify no corruption has occurred during the transmission of the PDU header. The iSR-6140 supports digest in hardware to maximize performance.

Select the check box to enable this option; clear the check box to disable it.

„Enable Data Digest – Enables or disables support for iSCSI data digest. Data digest is an ISCSI feature where a validity check field is added to iSCSI data to verify no corruption has occurred during the transmission of the data. The iSR-6140 supports digest in hardware to maximize performance.

Select the check box to enable this option; clear the check box to disable it.

„CHAP Settings – The CHAP Settings section provides the following parameters:

„Enable CHAP – Enables or disables CHAP (Challenge Handshake Authentication Protocol) support. Select the check box to enable this option; clear the check box to disable it.
