Supported iSCSI configurations include direct-attached and network-attached configurations. Both single-controller and HA pairs are supported.
In an iSCSI environment, all methods of connecting Ethernet switches to a network approved by the switch vendor are supported. Ethernet-only switch counts are not a limitation in Ethernet iSCSI configurations. For specific recommendations and best practices, see the Ethernet switch vendor's documentation.
