`
`Introducing the Crossroads 4100 Storage
`Router
`
`The Crossroads 4100 Storage Router provides bi-directional connectivity
`between a Fibre Channel Switched Fabric (FC-SW) or Fibre Channel
`Arbitrated Loop (FC-AL), and one FastAVide/Ultra SCSI bus.
`
`Supported devices include:
`
`Initiator Devices - Fibre Channel and SCSI hosts
`•
`• Direet Access Devices - RAID Controllers, Disk drives, JBODs
`•
`Sequential Access Devices - Tape drives
`• Changer Devices - Tape and Magneto-Optical Libraries

`
`How the 4100 Works
`
`The 4100 is a storage router that translates the Fibre Channel Protocol
`(FCP) to and from the SCSI Protocol so that Fibre Channel and SCSI
`devices can communicate with each otlier. It attaches to either a Fibre
`Channel or SCSI host, and transfers tlie command, data, and status
`information to SCSI or Fibre Channel targets. Packets are transferred
`transparently by the 4100 from host to targets and vice versa.
`
`Tlie 4100 provides interconnection between one SCSI bus and a Fibre
`Channel Arbitrated Loop or Switched Fabric. It takes advantage of Fibre
`Channel's ability to encapsulate SCSI protocol packets to allow a host
`with a FC or SCSI adapter to access SCSI or FC peripheral devices
`transparently over a FC connection.

`
`The air intake vents shown in Figure 1-2 provide cooling for the unit
`during operation and should always remain unobstructed. The exit vent
`for air is located on the back panel, shown in Figure 1-3.

`
`Besides the air vent, SCSI and Fibre Channel interfaces arc found on tlie
`back panel. Ethernet and Serial interfaces provide the means for
`configuring and managing the unit. The LEDs (operation indicators)
`provide basic status information about the unit. Finally, a power
`connector and a power switch are located on the back panel. For proper
`operationof tlie 4100,cable connectionson the back panelshould remain
`securely in place.

`The 4100 is both a SCSI and a Fibre Channel device operating on a SCSI
`bus and Fibre Channel network simultaneously.
`
`The SCSI Side
`
`On a SCSI bus, the 4100 acts as a SCSI initiator or target passing
`requests from hosts on tlie Fibre Channel network to target devices on
`the SCSI bus or from hosts on SCSI buses to targets on the Fibre
`Channel network. The 4100 SCSI bus uses one SCSI ID. The default
`Initiator ID is 7 and can be changed when configuring the 4100.
`
`The Fibre Channel Side
`
`In a Fibre Channel loop, the 4100 is identified by a single Arbitrated
`Loop Physical Address (AL_PA) or a fabric assigned Source ID. Once
`the address is acquired, any host on the Fibre Channel loop can access
`the devices on a SCSI bus transparently over a FC connection.
`
`Mapping Devices
`
`To allow Fibre Channel and SCSI devices to address each other, the
`4100 creates tables mapping device identifiers for Fibre Channel to SCSI
`and for SCSI to Fibre Channel. During 4100 configuration, you can
`choose the mapping methods and, in certain cases, customize device
`mappings. See Chapter 3 for more information about address modes and
`their configurations.

`
`Processing SCSI Information
`
`The following section describes how the 4100 processes SCSI
`information when attached to FC hosts. Figure l-S illustrates steps I
`through S of the process.
`
`1. A FC host issues a command. The FC host encapsulates the
`command in the FCP protocol and sends the packet to the 4100.
`
`2. The FC controller in the 4100 receives the packet, interprets the FC
`information, and places the packet in buffer inemoty.
`
`3. The 41 OO's processor interprets the information and programs a
`SCSI controller to process the transaction.
`
`4. The SCSI controller sends the command to the SCSI device (target).
`
`5. The SCSI target interprets the command and executes it.

`buffers. See Figure 1-6.

`
`Processing Fibre Channel Information
`
`Processing Fibre Channel information is the reverse of the process for
`processing SCSI information,described in the previous section. The
`4100 processes information from the SCSI host by requesting operations
`of targets on a Fibre Channel Storage Area Network (FC SAN). The
`difference in this case is tliat an initiator on the SCSI side issues
`commands and the information is passed through the 4100 to the FC
`SAN.

`
`Fibre Channel Connection
`
`Before connecting the 4100 to other Fibre Channel devices, it is
`important to understand the configuration requirements of the
`environment to which it will be connected. Failure to correctly configure
`a Fibre Channel device may impair the operation of the Storage Area
`Network to whieh it is attached.
`
`Typical installations will have the 4100 connected to either an Arbitrated
`Loop or Switched Fabric environment. For an Arbitrated Loop, the unit
`can be directly attached to the Fibre Channel host bus adapter, in a point-
`to-point fashion. Arbitrated Loops also allow for the use of Fibre
`Channel hubs, to which the unit can be directly attached. In Fibre
`Channel switched environments, the switch is directly attached to tlie
`4100.

`hub or switch port witli the appropriate FC cabling for the media type in
`use on both the 4100 and tlie port to which it is connected.
