Next steps
Install or enable MPIO on the host servers.
NOTE: After the Storage Center configuration is complete, run the host access wizard to configure
host server access and apply MPIO best practices. For the latest best practices, see the Dell Storage

Configure Embedded iSCSI Ports
One iSCSI Network with Dual Storage Controllers and Embedded Ethernet
Ports
Use one iSCSI network to prevent an unavailable port or storage controller from causing a loss of
connectivity between the host servers and a
storage system with dual storage controllers .
About this task
In this configuration, there are two fault domains, one iSCSI network, and one Ethernet switch. Each
storage controller connects to the Ethernet switch using two iSCSI connections.
• If a physical port becomes unavailable, the storage system is accessed from another port on the
Ethernet switch.
• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to
the physical ports on the other storage controller.
