HP MSA 1050 User Manual page 24

The MSA 1050 FC controllers support Fibre Channel Arbitrated Loop (public or private) or point-to-point topologies.
Loop protocol can be used in a physical loop or in a 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. See the set
host-parameters command within the CLI Reference Guide for command syntax and details about connection mode
parameter settings relative to supported link speeds.
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 "Using the
Configuration Wizard" and scroll to FC port options. 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
The MSA 1050 controller enclosures support 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 or approved DAC
cable supporting data rates up to 10 Gb/s, using either one-way or mutual CHAP (Challenge-Handshake Authentication
Protocol).
TIP: See the topics about configuring CHAP, and CHAP and replication in the SMU Reference Guide.
TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see "Using the
Configuration Wizard" and scroll to iSCSI port options. 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.
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 1050 controller enclosures support 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 Gb/s, using either one-way or mutual CHAP.
TIP: See the topics about configuring CHAP, and CHAP and replication in the SMU Reference Guide.
TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see "Using the
Configuration Wizard" and scroll to iSCSI port options. 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.
