Connecting hosts
NOTE:
MSA 2040 SAN controller enclosures support the optionally-licensed Remote Snap replication
feature. When using the web-browser interface, replication sets must be created, viewed, and managed
using the SMU v2. Replication sets can also be created and viewed using CLI commands.
Fibre Channel protocol
The MSA 2040 SAN controller enclosures support one or two controller modules using the Fibre Channel
interface protocol for host connection. Each controller module provides four host ports designed for use
with an FC SFP supporting data rates up to 16 Gbit/s. When configured with FC SFPs, MSA 2040 SAN
controller enclosures can also be cabled to support the optionally-licensed Remote Snap replication feature
via the FC ports.
The MSA 2040 SAN controller supports 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. See the
set host-parameters
command
within the
HP MSA 2040 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 CLI command
set
host-parameters
to set FC port options, and use the
show ports
command to view information
about host ports.
10GbE iSCSI protocol
The MSA 2040 SAN controller enclosures support one or two controller modules using the Internet SCSI
interface protocol for host connection. Each controller module provides four 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
“Using the Configuration Wizard” and scroll to iSCSI port options. Use the CLI command
set
host-parameters
to set iSCSI port options, and use the
show ports
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.
