Connect the Chassis to Hosts
See the topics about Configuring CHAP, and CHAP and replication in the disk management utility (V3).
Note: Use the disk management utility to set iSCSI port options. Within the disk management utility
(V3), 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.
The 10GbE iSCSI ports are used in either of two capacities:
To connect two storage systems through a switch for use of replication.
l
For attachment to 10GbE iSCSI hosts directly, or through a switch used for the 10GbE iSCSI traffic.
l
The first usage option requires valid licensing for the replication feature, whereas the second option requires
that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.

1 Gb iSCSI protocol

The QXS-3, QXS-4, and QXS-6 Series storage RAID chassis support two controller modules using the
Internet SCSI interface protocol for host port connection. Each controller module provides four iSCSI host
ports configured with an RJ-45 SFP supporting data rates up to 1 Gbit/s, using either one-way or mutual
CHAP.

HD mini-SAS technology

The QXS-3, QXS-4, and QXS-6 Series storage RAID chassis use high-density mini-SAS (Serial Attached
SCSI) interface protocol for host connection.
12 Gb HD mini-SAS ports
Each controller I/O module provides four SFF-8644 HD mini-SAS host ports supporting data rates up to 12
Gbit/s. HD mini-SAS host ports connect to hosts or switches; they are not used for replication. Use a
