Cabling the Embedded Ports for iSCSI Host Connectivity
A storage system that is configured for virtual port mode can use the management port and replication
port for front-end iSCSI host connectivity.
Dell recommends using two switches dedicated for iSCSI traffic. Refer to the iSCSI Settings appendix for a
list of recommend and required settings.
Two iSCSI Networks using the Embedded Ethernet Ports on a Storage System
with Fibre Channel Storage Controllers
Use two iSCSI networks to prevent an unavailable port, switch, or storage controller from causing a loss
of connectivity between the host servers and a storage system with dual Fibre Channel (FC) storage
controllers.
About this task
This configuration includes two fault domains, two iSCSI networks, and two Ethernet switches.
• If a physical port or Ethernet switch becomes unavailable, the storage system is accessed from the
switch in the other fault domain.
• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to
the physical ports on the other storage controller.
NOTE: In this configuration, Storage Center system management traffic and iSCSI traffic use the
same physical network ports. For environments where the Storage Center system management
ports are mixed with network traffic from other devices (such as voice, backups, or other computing
devices), separate iSCSI traffic from management traffic using VLANs.
Steps
1.
Connect each server and Ethernet switch 1 to the corporate/management network (shown in green).
2. Connect the servers that support iSCSI connections to both iSCSI networks.
3. Connect embedded fault domain 1 (shown in orange) to iSCSI network 1.
