Use only QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 system or
OEM-qualified cables to connect host to RAID chassis:
•
Qualified Fibre Channel SFP and cable options
•
Qualified 10GbE iSCSI SFP and cable options
•
Qualified 1Gb RJ-45 SFP and cable options
A host 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. Cable connections vary depending on
configuration. This section describes host interface protocols supported by QXS-G2-312,
QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID chassis, while showing a few
common cabling configurations.
NOTE:
QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 controllers use
Unified LUN Presentation (ULP), which enables a host to access mapped volumes through any
controller host port.
ULP can show all LUNs through all host ports on both controllers, and the interconnect information is
managed by the controller firmware. ULP appears to the host as an active-active storage system,
allowing the host to select any available path to access the LUN, regardless of disk group ownership.
TIP:
See the topic about configuring system settings in the
QXS G2 Disk Management Utility User
Guide
to initially configure the system, or change system configuration settings (such as Configuring
host ports).
CNC Technology
The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 FC/iSCSI models use
Converged Network Controller (CNC) technology, allowing you to select the desired host interface
protocol(s) from the available FC or iSCSI host interface protocols supported by the system. The small
form-factor pluggable (SFP transceiver or SFP) connectors used in CNC ports are further described in
the subsections below.
Refer to the following for additional CNC information:
•
QXS-G2-412, QXS-G2-424, and QXS-G2-484 RAID Chassis Rear View (4-Host Port Controllers)
•
QXS-G2-312 and QXS-G2-324 RAID Chassis Rear View (2-Host Port Controllers)
•
5U84 RAID Chassis (Rear View/Two CNC Controllers)
NOTE:
Controller modules are shipped with SFPs installed (FC or iSCSI per customer order).
CAUTION:
Use the
set host-port-mode
CLI command to set the host interface protocol for CNC
ports using qualified SFP options (if required).
•
QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 models ship with CNC
ports configured for FC or iSCSI per customer order.
•
Using FC or iSCSI SFPs in combination is not supported currently.
