Basic Network Structure

When a storage router is deployed for 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.

VLAN Access Overview

Storage router VLAN access provides IP hosts with access to storage devices
according to the VLAN to which each host belongs.
Figure 42
the figure, a storage router Gigabit Ethernet interface is connected to an IP
network through an IEEE 802.1Q trunk; the storage router Fibre Channel
interfaces are connected to storage devices 1, 2, and 3. The storage router is
configured with two SCSI routing instances named SR100 and SR200. The IP
network contains two VLANs: VLAN 100 and VLAN 200. The SCSI routing
instance, SR100, is configured to allow the hosts in VLAN 100 to access storage
devices 1 and 2. The SCSI routing instance, SR200, is configured to allow the
hosts in VLAN 200 to access storage device 3.
