For proper iSCSI
multipathing and
scalability, only one
uplink can be active
for each iSCSI
VMkernel port. All
others must be set
to unused.
What's the Maximum Number of Links That You Can Use for iSCSI?
You can use the method shown previously to drive I/O down eight separate vmnics. Testing has
shown that vSphere can drive nine Gbps of iSCSI throughput through a single ESXi host.
For more information on how to create a vSwitch, assign uplinks, create VMkernel ports, and
modify the NIC failover order for a vSwitch or VMkernel port, refer to Chapter 5.
When you i nish with the networking coni guration, you're ready for the next step.
Activating and Confi guring the Software iSCSI Initiator
After coni guring the network appropriately for iSCSI, perform these steps to activate and con-
i gure the software iSCSI initiator:
1.
In the vSphere Web Client, navigate to the Hosts And Clusters view and select an ESXi
host from the inventory panel.
2.
Click the Manage tab and select the Storage subsection.
3.
Click the Add New Storage Adapter icon. From the Add Storage Adapter drop-down,
select Software iSCSI Adapter and click OK.
4.
A dialog box will appear, informing you that a software iSCSI will be added to the list of
storage adapters. Click OK.
