VLAN Access Overview
Basic Network Structure
When a storage router is deployed for SCSI routing or transparent SCSI routing and FCIP, IP hosts with iSCSI drivers access the storage router through the IP network connected to the storage router’s Gigabit Ethernet interfaces. The storage router accesses the storage devices or intelligent storage array connected to the Fibre Channel interfaces. Access to the FC interfaces is made through the internal FC initiator interface configured for iSCSI traffic.
The internal FC initiator interface configured for FCIP allows the FC hosts or FC devices to connect to one or more Fibre Channel interfaces of the peer systems, which are connected to the IP network through a Gigabit Ethernet interface. Through the IP network, each FCIP instance accesses its peer, thereby connecting the SANs. Redundant network structures are also supported.
A management station manages the storage router through an IP network connected to the management interface. A storage router deployed for SCSI routing and FCIP can also participate in a cluster to provide HA operations for SCSI routing. When the storage router is deployed for transparent SCSI routing and FCIP, the HA operations for SCSI routing are controlled in the intelligent storage array. and the HA interface on the storage router is disabled.
