SCSI Routing Overview

Routing SCSI Requests and Responses

SCSI routing consists of routing SCSI requests and responses between hosts in an IP network and FC storage. (See Figure 1-5.)

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.

SCSI routing consists of the following main actions (See Figure 1-6):

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

•Routing SCSI requests and responses between hosts on an IP network and FC storage

•Transporting SCSI requests and responses between the SN 5428-2 Storage Router and FC storage
