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.

VLAN Access Overview

SN 5428-2 VLAN access provides IP hosts with access to storage devices according to the VLAN to which each host belongs.

Figure 1-21shows a sample network that employs SN 5428-2 VLAN access. In the figure, an SN 5428-2 Gigabit Ethernet interface is connected to an IP network through an IEEE 802.1Q trunk; the SN 5428-2 Fibre Channel interfaces are connected to storage devices 1, 2, and 3. The SN 5428-2 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.

In an IP host, the iSCSI driver is configured with the Gigabit Ethernet IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses. In a storage router, access is controlled through an access list and a VLAN identifier VID number of the hosts. Additionally, access can be further controlled in the SN 5428-2 through authentication.
