Routing SCSI Requests and Responses
SCSI routing consists of routing SCSI requests and responses between hosts in an
IP network and FC storage.
Figure 32: Routing SCSI requests and responses for SCSI routing
Each host that requires IP access to storage via an IP Storage Router 2122-2 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
