System monitoring features
This section describes the different types of system monitoring features that provide the operating status
of each component.
1.5.1 Expansion enclosure support
Monitoring system
A managing DS 3000 system is aware of the status of connected expansion system’s components such
as:
•
Expander controller (presence, voltage, and thermal readings)
•
PSU
•
Cooling module
•
Enclosure thermal sensor
•
Service (the Service LED signals the specific enclosure)
•
Disk drives
Expansion system identifier
The managing system sets off the alarm and deliver the warning messages if there is a conflict between
the expansion systems.
If more than one expansion system is connected to the managing DS system, each needs a unique
enclosure ID set using the rotary switch on the LED panel. For example, the firmware automatically
disconnects the second expansion system if it is connected online and comes with an ID identical to the
first expansion system.
NOTE:
The expansion system IDs are numbers 1 to 15. For more details, see section
.
Cooling module speed adjustment
If any of the detected temperature readings breaches the temperature threshold, the firmware running
on the managing DS system automatically increases the rotation speed of all cooling fans.
Expansion enclosure status monitoring
When connecting with expansion systems, you can acquire the component status with other enclosures
via a propriety enclosure monitoring service using the in-band connectivity. No additional management
connection is required.
I
2
C bus
The detection circuitry and temperature sensors are interfaced via a non-user-serviceable I
2
C bus.
When the expansion systems are connected to DS controllers, the component status is reported through
in-band protocols over expansion links, which is managed by a proprietary enclosure service.
Firmware (FW) and SANWatch
•
Firmware:
The firmware (FW) is preloaded and is used to configure the system. Access the FW via
a terminal emulation program running on a management computer connected to the system’s serial
port.
•
SANWatch:
SANWatch is another browser-based GUI (graphic user interface) software that you
can install into a local or remote computer and access via the network. The managing system
communicates with the array via connection of the existing host links or the Ethernet link to the
array’s Ethernet port.
