SCSI Routing

 

Routing SCSI from the IP host to the Fibre Channel storage device consists of the following main actions:

The iSCSI requests and responses are transported over an IP network between the hosts and the IPS module or MPS-14/2 module.

The SCSI requests and responses are routed between the hosts on an IP network and the Fibre Channel storage device (converting iSCSI to FCP and vice versa). The IPS module or MPS-14/2 module performs this conversion and routing.

The FCP requests or responses are transported between the IPS module or MPS-14/2 module and the Fibre Channel storage devices.

FCP (the Fibre Channel equivalent of iSCSI) carries SCSI commands over a Fibre Channel SAN. Refer to the IETF standards for IP storage at http://www.ietf.org for information on the iSCSI protocol.
