The first usage option requires valid licensing for the Remote Snap replication feature, available with the HPE MSA
Advanced Data Services license, whereas the second option requires that the host computer supports iSCSI and
optionally, multipath I/O.
TIP Use the SMU to view or change iSCSI port settings, as described in the Storage Management Guide.
Alternatively, the following CLI commands can be used:
l
Use the
set host-parameters
CLI command to set iSCSI port parameters for communication with hosts.
l
Use the
show ports
CLI command to view information about host ports in each controller module.
l
Use the
set iscsi-parameters
CLI command to change system-wide parameters for iSCSI ports.
l
Use the
show iscsi-parameters
CLI command to show system-wide parameters for iSCSI ports.
See the CLI guide for information about commands, syntax, and important information concerning command usage.
SAS protocol
MSA 1060/2060/2062 SAS controller enclosures support SAS (Serial Attached SCSI), which is a point-to-point serial
protocol for moving data to and from storage devices. SAS uses the standard SCSI command set. SAS host interface
ports connect to server HBAs using direct attach or a SAS interconnect if using blade systems. SAS host interface ports
are used for I/O traffic and do not support the HPE MSA Remote Snap replication feature.
About data host connection
An initiator identifies an external port to which the storage system is attached. The external port may be a port in an
I/O adapter (such as an FC HBA) in a server, or a connected switch. Cable connections vary depending on configuration.
Common cabling configurations for the host interface protocols previously described are shown in the following
sections. Supporting diagrams describe direct attach, switch-connect, and storage expansion configuration options for
MSA 1060/2060/2062 products. For specific information about qualified host cabling options for your product, see the
appropriate QuickSpecs:

MSA 2060 and MSA 2062 Storage
MSA 2060/2062 Storage systems support FC, iSCSI, and SAS host interface protocols. The MSA 2060/2062 FC and iSCSI
controller modules use small form-factor pluggable (SFP transceiver or SFP) connectors and cable options, as shown in
the illustration. The example shows a 4-port controller module; however, this concept applies equally to the MSA 1060
FC model.
