Transparent SCSI Routing Overview

Routing SCSI Requests and Responses

Transparent SCSI routing consists of routing SCSI requests and responses between hosts in an IP network and an intelligent storage array that is directly connected to an SN 5428-2 Fibre Channel interface. (See Figure 1-10.)

Each host that requires IP access to storage via an SN 5428-2 Storage Router needs to have a compatible iSCSI driver installed. Using the iSCSI protocol, the iSCSI driver allows an IP host to transport SCSI requests and responses over an IP network. From the perspective of a host operating system, the iSCSI drive appears to be a locally attached SCSI or Fibre Channel drive to the host. From the perspective of the storage array, each IP host appears as an FC host (with one Fibre Channel address for each host).

Transparent SCSI routing consists of the following main actions (Figure 1-11):

Transporting SCSI requests and responses over an IP network between the hosts and the SN 5428-2 Storage Router.

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.
