What should an administrator do to configure multi-pathing using software iSCSI?
A. Bind the VMkernel ports to the software iSCSI initiator
B. Configure Zoning between the hosts and SAN switches
C. Configure NIC teaming on the associated uplinks
D. Ensure jumbo frames are enabled end-to-end
Correct Answer: A
Explanation/Reference:
Explanation:
We can configure multipathing with Software iSCSI initiators using port binding.
Software and dependent hardware iSCSI adapters depend on VMkernel networking. If you use the software or dependent hardware iSCSI adapters, you must configure connections for the traffic between the iSCSI component and the physical network adapters. Configuring the network connection involves creating a virtual VMkernel interface for each physical network adapter and associating (binding) the interface with an appropriate iSCSI adapter.
Procedure
Browse to the host in the vSphere Web Client navigator.
Click the Manage tab, and click Storage.
Click Storage Adapters and select the software or dependent iSCSI adapter to configure from the list.
Under Adapter Details, click the Network Port Binding tab and click Add.
Select a VMkernel adapter to bind with the iSCSI adapter.
You can bind the software iSCSI adapter to one or more VMkernel adapters. For a dependent hardware iSCSI adapter, only one VMkernel adapter associated with the correct physical NIC is available.
Click OK.
Incorrect Answers:
B: Zoning is a feature used for partitioning Fibre Channel networks. It is not used in iSCSI. Therefore, this answer is incorrect.
C: NIC teaming is used to combine multiple network adapters into one virtual network adapter for redundancy and bandwidth purposes. It is not required to configure iSCSI multipathing. Therefore, this answer is incorrect.
D: Jumbo frames are Ethernet frames with more than 1,500 bytes of payload (MTU). They are used to improve network performance by carrying more data per frame. They are not required to configure iSCSI multipathing. Therefore, this answer is incorrect.
