Flow control manages the rate of data transmission between two nodes to prevent a fast sender from
overrunning a slow receiver. For best results, enable ow control at the end points of the I/O path, at the
hosts and iSCSI storage systems.
To enable ow control for the host, use the esxcli system module parameters command. For details,

Dependent hardware adapters support IPv4 and IPv6.
Configure Dependent Hardware iSCSI Adapters
The entire setup and conguration process for the dependent hardware iSCSI adapters involves several
steps. After you set up your adapter, you might need to congure CHAP parameters and Jumbo Frames.
Procedure
1 View Dependent Hardware iSCSI Adapters on page 75
View a dependent hardware iSCSI adapter to verify that it is correctly loaded.
2 Modify General Properties for iSCSI Adapters on page 76
You can change the default iSCSI name and alias assigned to your iSCSI adapters. For the for
independent hardware iSCSI adapters, you can also change the default IP seings.
3 Determine Association Between iSCSI and Network Adapters on page 76
You create network connections to bind dependent iSCSI and physical network adapters. To create the
connections correctly, you must determine the name of the physical NIC with which the dependent
hardware iSCSI adapter is associated.
4 Create Network Connections for iSCSI on page 77
Congure connections for the trac between the software or dependent hardware iSCSI adapters and
the physical network adapters.
5 Set Up Dynamic or Static Discovery for iSCSI on page 80
With dynamic discovery, each time the initiator contacts a specied iSCSI storage system, it sends the
SendTargets request to the system. The iSCSI system responds by supplying a list of available targets
to the initiator. In addition to the dynamic discovery method, you can use static discovery and
manually enter information for the targets.
What to do next
If required, congure CHAP parameters and jumbo frames.
View Dependent Hardware iSCSI Adapters
View a dependent hardware iSCSI adapter to verify that it is correctly loaded.
If installed, the dependent hardware iSCSI adapter (vmhba#) appears on the list of storage adapters under
such category as, for example, Broadcom iSCSI Adapter. If the dependent hardware adapter does not appear
on the list of storage adapters, check whether it needs to be licensed. See your vendor documentation.
Procedure
1 Browse to the host in the vSphere Web Client navigator.
2 Click the Manage tab, and click Storage.
3 Click Storage Adapters.
4 Select the adapter (vmhba#) to view.
The default details for the adapter appear, including the iSCSI name, iSCSI alias, and the status.
