Major Fibre Channel Port Features
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A General Description 1-5
• Devices in the same segmented loop zone communicate with one another as
though they were on the same physical loop.
• Devices on SL_Ports cannot communicate with devices on F, FL or
TL_Ports. They also cannot communicate with devices on SL_Ports which
are not in the same segmented loop zone.
• Devices connected to SL_Ports are not registered with the Name Server.
• Each loop segment may have a Fibre Channel Frame in process.
• You may have as many loop segments as you have SL_Ports. That is, if none
of them are zoned together, each SL_Port would contain one set of AL_PA
and each AL_PA within that loop must be unique.
• The Switch supports all SCSI/FCP and TCP/IP frames.
• SL_Ports support Class 2 and 3 Fibre Channel Service.
SL_Port Management
Refer to the Switch Management manual for more information. The SANsurfer
Web-based Switch management application provides the following:
• The user may choose which ports (if any) are SL_Ports.
• The user may place up to 32 SL_Ports together in the same segmented loop
zone to form each Segmented Loop.
• The application provides a map of all AL_PAs on a Segmented Loop. This
viewable map includes information about which AL_PA address are being
used by the SL_Port.
• The application provides a way to flag error conditions to the user.
• All management configuration information is stored in non-volatile memory.
SL Private Loop Stage Type
Switch management allows you to define a chassis as an SL Private Loop stage
type. This stage type defines all ports on the chassis as SL_Ports and links them
into one segmented loop. If an SL Private Loop chassis is to be used in a cascade
topology, all chassis in that topology must also be SL Private Loop. Furthermore,
an SL Private Loop chassis in a multi-chassis fabric will force all other chassis in
that fabric to behave as SL Private Loop chassis. You may not mix SL Private Loop
chassis with other stage types in the same fabric.
You define an SL Private Loop chassis by selecting SL Private Loop as the stage
type in the Chassis Parameters portion of any Switch Faceplate Display in the
SANSurfer Switch Management application. Refer to the Switch Management
manual for more information.
