Direct-Attached iSCSI Connections
This section describes how to directly connect a host to a two-controller storage system and a four-controller storage system through iSCSI multi-path connections.
Two-Controller Storage System
Figure 3-5 shows how to directly connect a host to a 2 U two-controller storage system through iSCSI multi-path connections.
In this connection diagram, each of the two controllers is connected to a host NIC port with an Ethernet cable.

- IP addresses in this table are for reference only. Plan IP addresses based on site requirements.
- If you use LLDesigner to plan connectivity, you can obtain IP address data from the IP Address Planning worksheet in the exported LLD file.
Four-Controller Storage System
Figure 3-6 shows how to directly connect a host to a 4 U four-controller storage system through iSCSI multi-path connections.
In this connection diagram, each of the four controllers is connected to a host NIC port with an Ethernet cable.
