SCSI Routing Overview

Chapter 1 Before Configuring SN 5428-2 Storage Router Software

SCSI Routing Overview

•LUN Trespass feature—provides a LUN failover feature for selected storage arrays that operate on the active/passive port model. When enabled, the trespass feature provides a redundant path from the storage router to the storage array by allowing the storage router to detect a path failure to a storage array port and perform the necessary operations to fail LUNs over to the other port on the storage array without using any multi-path software.

•TCP Window Tuning—provides the ability to maximize bandwidth across the network by automatically setting the local TCP receive window size to the remote TCP receive window size without user intervention

•A command-line interface (CLI) and a web-based GUI—provides user interfaces for configuration and maintenance of an SN 5428-2

SCSI Routing Overview

SCSI routing provides IP hosts with access to FC storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the SN 5428-2 Storage Router. An iSCSI target is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the SN 5428-2. The storage router presents the iSCSI targets to IP hosts as if the physical storage devices were directly attached to the hosts. (See Figure 1-4.) With SCSI routing, storage devices are not aware of each IP host; the storage devices are aware of the SN 5428-2 and respond to it as if it were one FC host.

To configure an SN 5428-2 Storage Router for SCSI routing, you should have a basic understanding of the following concepts:

•Routing SCSI Requests and Responses, page 1-5

•Basic Network Structure, page 1-6

•SCSI Routing Mapping and Access Control, page 1-6

•Available Instances of SCSI Routing, page 1-9

Note Along with FC storage, FC host connections and FC switch connections are allowed; however, most of the illustrations in this manual show only storage connections for the purpose of describing the

SN 5428-2 Storage Router features.
