SN 5428-2 Storage Router Overview

The Cisco SN 5428-2 Storage Router provides universal access to storage over IP networks. The storage router software controls the operation of the Cisco SN 5428-2 Storage Router. You can configure the software to provide the following types of access to storage over IP networks:

SCSI routing only

Transparent SCSI routing only

FCIP only

SCSI routing and FCIP

Transparent SCSI routing and FCIP

SCSI routing provides IP hosts with access to Fibre Channel (FC) storage devices, using iSCSI protocol. The iSCSI protocol is an IETF-defined protocol for IP storage (ips).

Note For more information about the iSCSI protocol, refer to the IETF standards for IP storage at http://www.ietf.org.

With SCSI routing, storage device access is managed primarily in the SN 5428-2. (See Figure 1-1.)

Transparent SCSI routing provides IP hosts with transparent access to intelligent storage arrays using iSCSI protocol; that is, each IP host is presented as an FC host to an intelligent storage array. With transparent SCSI routing, availability of storage devices is managed primarily in the intelligent storage array. (See Figure 1-2.)

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.
