With the software-based iSCSI implementation, you can use standard NICs to connect your host to a remote iSCSI target on the IP network. The software iSCSI adapter that is built into ESXi facilitates this connection by communicating with the physical NICs through the network stack.

Before you can use the software iSCSI adapter, you configure it by activating the adapter and setting up its networking.

Designate a separate network adapter for iSCSI. Do not use iSCSI on 100Mbps or slower adapters.


You must activate your software iSCSI adapter so that your host can use it to access iSCSI storage.


Configure connections for the traffic between the software or dependent hardware iSCSI adapters and the physical network adapters.
