Grouping iSCSI I/O Ports Using Fault Domains
Front-end ports are categorized into fault domains that identify allowed port movement when a controller reboots or a port fails. Ports
that belong to the same fault domain can fail over to each other because they have connectivity to the same resources.
NOTE:
Fault domains cannot be added or modified on SCv2000 or SCv3000 series storage systems. Storage Center
creates and manages fault domains on these systems.
iSCSI VLAN Tagging Support
iSCSI ports in a fault domain can be configured to use a VLAN ID. For each Storage Center, one of two levels of VLAN functionality is
available depending on the Storage Center OS version, Storage Center controller model, and iSCSI hardware. Basic VLAN functionality is
referred to as single-VLAN tagging, and enhanced VLAN functionality is referred to as multi-VLAN tagging.
