Lenovo S3200 Setup Manual: Fibre Channel Protocol

NOTE: Controller modules are not shipped with pre-installed SFPs. Within your product kit, you will need
to locate the qualified SFP options, and install them into the CNC ports. See
page 80.
IMPORTANT: Use the set host-port-mode CLI command to set the host interface protocol for CNC
ports using qualified SFP options. S3200/S2200 models ship with CNC ports configured for FC. When
connecting CNC ports to iSCSI hosts, you must use the CLI (not the SMC) to specify which ports will use
iSCSI. It is best to do this before inserting the iSCSI SFPs into the CNC ports (see
mode
on page 44 for instructions).

Fibre Channel protocol

S3200/S2200 FC controller enclosures support one or two controller modules using the Fibre Channel
interface protocol for host connection. The S3200 FC controller module provides four host ports, and the
S2200 FC controller module provides two host ports. The CNC ports are designed for use with an FC SFP
supporting data rates up to 16 Gbit/s.
The controllers support Fibre Channel Arbitrated Loop (public or private) or point-to-point topologies. Loop
protocol can be used in a physical loop or for direct connection between two devices. Point-to-point
protocol is used to connect to a fabric switch. Point-to-point protocol can also be used for direct connection,
and it is the only option supporting direct connection at 16 Gbit/s. See the set host-parameters
command within the CLI Reference Guide for command syntax and details about parameter settings
relative to supported link speeds. Fibre Channel ports are used for attachment to FC hosts directly, or
through a switch used for the FC traffic. The host computer must support FC and optionally, multipath I/O.
TIP: Use the SMC Configuration Wizard to set FC port speed. Within the Storage Manager Guide, see
"Configuring host ports." Use the set host-parameters CLI command to set FC port options, and use
the show ports CLI command to view information about host ports.
10GbE iSCSI protocol
S3200/S2200 10GbE iSCSI controller enclosures support one or two controller modules using the Internet
SCSI interface protocol for host connection. The S3200 10GbE iSCSI controller module provides four host
ports, and the S2200 10GbE iSCSI controller module provides two host ports. The CNC ports are
designed for use with a 10GbE iSCSI SFP supporting data rates up to 10 Gbit/s, using either one-way or
mutual CHAP (Challenge-Handshake Authentication Protocol). The 10GbE iSCSI ports are used for
attachment to 10GbE iSCSI hosts directly, or through a switch used for the 10GbE iSCSI traffic. The host
computer must support Ethernet, iSCSI, and optionally, multipath I/O.
TIP: See the "Configuring CHAP" topic in the Storage Management Guide.
TIP: Use the SMC Configuration Wizard to set iSCSI port options. Within the Storage Manager Guide,
see "Configuring host ports." Use the set host-parameters CLI command to set iSCSI port options,
and use the show ports CLI command to view information about host ports.
1 Gb iSCSI protocol
S3200/S2200 1 Gb iSCSI controller enclosures support one or two controller modules using the Internet
SCSI interface protocol for host port connection. The S3200 1 Gb iSCSI controller module provides four
host ports, and the S2200 1 Gb iSCSI controller module provides two host ports. The CNC ports are
designed for use with an RJ-45 SFP supporting data rates up to 1 Gbit/s, using either one-way or mutual
CHAP (Challenge-Handshake Authentication Protocol). The 1 Gb iSCSI ports are used for attachment to 1
