Dependent Hardware<br />
iSCSI<br />
The advanced iSCSI settings control such parameters as header and data digest, ARP redirection, delayed ACK,<br />
and so on. Generally, you do not need to change these settings because your host works with the assigned<br />
predefined values.<br />
CAUTION Do not make any changes to the advanced iSCSI settings unless you are working with the <strong>VMware</strong><br />
support team or otherwise have thorough information about the values to provide for the settings.<br />
Required privilege: Host.Configuration.<strong>Storage</strong> Partition Configuration<br />
Procedure<br />
1 Access the iSCSI Initiator Properties dialog box.<br />
2 To configure advanced parameters at the initiator level, on the General tab, click Advanced. Proceed to<br />
Step 4.<br />
3 Configure advanced parameters at the target level.<br />
At the target level, advanced parameters can be configured only for software and dependent hardware<br />
iSCSI adapters.<br />
a Select either the Dynamic Discovery tab or Static Discovery tab.<br />
b From the list of available targets, select a target to configure and click Settings > Advanced.<br />
