72 QXS G2 Hardware Installation and Maintenance Guide
Testing Chassis Connections
See Powering On/Powering Off on page 105. Once the power-on sequence succeeds, the storage
system is ready to be connected as described in Host Connection on page 76.
Grounding Checks
The product must only be connected to a power source that has a safety electrical earth connection.
CAUTION: If more than one chassis goes into a rack, the importance of the earth connection to the
rack increases because the rack will have a larger Earth Leakage Current (Touch Current).
Examine the earth connection to the rack before power on. An electrical engineer who is qualified to
the appropriate local and national standards must do the examination.
Host System Requirements
NOTE:
Refer to the QXS-G2 (12G) Quantum Interoperability and Certification Matrix for Quantum
model numbers, firmware release, firmware required for host systems, RAID hardware certifications,
and HBA attach.
Hosts connected to QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 systems
must meet the following requirements:
• Depending on your system configuration, host operating systems may require that multipathing is
supported.
• If fault tolerance is required, then multipathing software may be required.
• Host-based multipath software should be used in any configuration where two logical paths
between the host and any storage volume may exist at the same time.
• This would include most configurations where there are multiple connections to the host or
multiple connections between a switch and the storage.
• Use native Microsoft MPIO DSM support with Windows Server 2008, Windows Server 2012, and
Windows Server 2016.
Use either the Server Manager or the
mpclaim
CLI tool to perform the installation.
See the following web sites for information about using native Microsoft MPIO DSM:
• https://support.microsoft.com
• https://technet.microsoft.com (search the site for “multipath I/O overview”)
Cabling Considerations
Common cabling configurations address hosts, RAID chassis, expansion chassis, and switches. Host
interface ports on the QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID
chassis can connect to respective hosts via direct-attach or switch-attach. Cabling systems to enable
use of the optional replication feature—to replicate volumes—is yet another important cabling
consideration. See Connecting Management Host to Network on page 83. The FC and iSCSI product
models can be licensed to support replication.
