HP MSA 1040 SAN Storage - Manual (Page 30)

30 Connecting hosts
Fibre Channel ports are used in either of two capacities:
• To connect two storage systems through a Fibre Channel switch for use of Remote Snap replication.
• For attachment to FC hosts directly, or through a switch used for the FC traffic.
The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second
option requires that the host computer supports FC and optionally, multipath I/O.
TIP: Use the SMU Configuration Wizard to set FC port speed. Within the SMU Reference Guide, see
“Configuring the system > Using the Configuration Wizard > Configuring host ports,” and scroll to FC port
options. Use the CLI command set host-parameters to set FC port options, and use either the show
host-parameters
or show ports commands to view information about host ports.
10GbE iSCSI protocol
The MSA 1040 controller enclosures support one or two controller modules using the Internet SCSI
interface protocol for host connection. Each controller module provides two host ports 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).
TIP: See the “Configuring CHAP” topic in the SMU Reference Guide. Also see the important statement
about CHAP preceding the “Using the Replication Setup Wizard” procedure within that guide.
TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see
“Configuring the system > Using the Configuration Wizard > Configuring host ports,” and scroll to iSCSI
port options. Use the CLI command set host-parameters to set iSCSI port options, and use either the
show host-parameters
or show ports commands to view information about host ports.
The 10GbE iSCSI ports are used in either of two capacities:
• To connect two storage systems through a switch for use of Remote Snap replication.
• For attachment to 10GbE iSCSI hosts directly, or through a switch used for the 10GbE iSCSI traffic.
The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second
option requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.
1 Gb iSCSI protocol
The MSA 1040 controller enclosures support one or two controller modules using the Internet SCSI
interface protocol for host port connection. Each controller module provides two iSCSI host ports
configured with an RJ-45 SFP supporting data rates up to 1 Gbit/s, using either one-way or mutual CHAP.
TIP: See the “Configuring CHAP” topic in the SMU Reference Guide. Also see the admonition about
CHAP preceding the “Using the Replication Setup Wizard” procedure within that guide.
TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see
“Configuring the system > Using the Configuration Wizard > Configuring host ports,” and scroll to iSCSI
port options. Use the CLI command set host-parameters to set iSCSI port options, and use either the
show host-parameters
or show ports commands to view information about host ports.
The 1 Gb iSCSI ports are used in either of two capacities:
• To connect two storage systems through a switch for use of Remote Snap replication.
• For attachment to 1 Gb iSCSI hosts directly, or through a switch used for the 1 Gb iSCSI traffic.
