DMM Management and SBMC
Depending on the number and organization of modules and chassis, DMM management can include
these four levels:
• Domain: One to eight chassis logically linked in a single management environment; the top level
of DMM management
• Virtual Group: A logical set of two to 128 of the same type of module that can be in different
chassis or remote linked partners, but all within the domain; the DMM supports up to 32 Virtual
Groups
• Chassis: An enclosure that holds and provides power to two or more modules
• Module: A single card, typically mounted in a chassis; you can access and manage some
modules directly through the EIA-232 serial port
Two modules support management at the chassis and domain levels:
• A Chassis Interconnect Module (CIM) in each chassis in the domain collects data and alarms
from all modules and power supplies in the chassis. The CIM also monitors status of all linked
chassis. For details, see the User Manual for your CIM(s).
• The DMM provides a serial port for VT100 Terminal and modem support and a 10BASE-T port
for IP based protocol support with SNMP MIB II and Canoga Perkins Enterprise MIBs for each
module in the Domain.
The DMM uses HDLC to extend management from the DMM, across the backplane to local modules,
and through the CIM to modules in other chassis. SBMC extends management through chassis-based
modules to their remote link partners. When CIMs interconnect two or more UCS chassis in a
domain, the DMM can manage all connected chassis and remote devices through the CIMs. SBMC
carries these controls and information across the fiber optic links to remote locations:
• Software upgrades and flash memory bank switching
• Configuration data and changes
• Operational status
• Alarm indicators
Exact SBMC implementation varies between devices, and may not be available for a passive module.
Software upgrades for the DMM and all active modules are available on the Canoga Perkins Web
site. You can transfer upgrades to the DMM by Trivial File Transfer Protocol (TFTP) and archive
them in the DMM Software Library to store, track, and distribute current and former software
revisions to all connected devices.
For example, you may need to upgrade a group of modules with new firmware when you install a
new module, with newer firmware than its link partner, in the domain. The discrepancy in versions
appears in the DMM status. Through various Domain and Virtual Group functions, you can
distribute the new firmware to the older modules, then reset them to use the new firmware.
