Available Instances of SCSI Routing

You can configure an SN 5428-2 Storage Router with up to 12 instances of SCSI routing services. Each instance needs to be configured with the following:

One or more unique IP addresses assigned to either one or both Gigabit Ethernet interfaces

Mapping between iSCSI target names and physical storage addresses

Access control

When an SN 5428-2 is part of a cluster, an instance of SCSI routing can run on only one storage router in a cluster at any given time. See the “SN 5428-2 Cluster Management Overview” section on page 1-25for more information about storage router clusters.

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.
