Installation 75

The 10GbE iSCSI ports are used in either of two capacities:

• To connect two storage systems through a switch for use of 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 replication feature, whereas the second option

requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.

TIP: See the topic about configuring CHAP in the

QXS G2 Disk Management Utility User Guide

TIP: Use the disk management utility (GUI) to set iSCSI port options. Within the

QXS G2 Disk

Management Utility User Guide

, see the topic about 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.

1Gb iSCSI Protocol

The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis 1Gb iSCSI

controllers support two controller modules using the Internet SCSI interface protocol for host port

connection.

• The QXS-G2-312 and QXS-G2-324 1Gb iSCSI controller module provides two host ports.

• The QXS-G2-412, QXS-G2-424, and QXS-G2-484 1Gb iSCSI controller module provides four host

ports.

• The CNC ports are designed for use with an RJ-45 SFP supporting data rates up to 1Gb/s, using

either one-way or mutual CHAP.
