iSCSI Guidelines
If you are configuring multiple cards for iSCSI, ensure each card is placed on a different subnet. If
both iSCSI ports are configured for the same subnet, the configuration will fail.
In the ION Configuration Setup screens, ensure you selected the iSCSI protocol (and enabled HA,
if applicable).
If you need to set the MTU (Maximum Transmission Units) value for an iSCSI port,
1. Select General.
2. Press Tab until you reach the “down arrow” icon and then choose an MTU value from the
dropdown list.
Configuring iSCSI Split-Port Capability
For additional information on port splitting for iSCSI, refer to to Split-Function Ports for iSCSI –
Dell R720 in Appendix A: Dell PowerEdge R720 Configuration.
In the Network Settings screen, each network card has its own unique Bus ID and MAC address.
(The second port on the same card does not show the Bus ID.)
With three Mellanox ConnectX-3 cards installed in slots 1, 2, and 3, the corresponding bus IDs are as
follows:
• Slot# 1  bus ID 0000:41:00.0
• Slot# 2  bus ID 0000:44:00.0
• Slot# 3  bus ID 0000:43:00.0
Below is a sample two-node HA configuration, using a cluster interconnect setup in split-port mode:
• Node1, slot 1, port1 (192.168.1.1)  Node2, slot1, port1 (192.168.1.2)
• Node1, slot 2, port1 (192.168.2.1)  Node2, slot2, port1 (192.168.2.2)
