Systems Management Features
• A Chassis Management Controller (CMC), which provides several
essential systems management features:
– Enclosure-level power management and thermal management:
• The CMC monitors system power requirements and supports the
optional Dynamic Power Supply Engagement mode so that the
CMC can enable or place power supplies in standby dynamically,
depending on load and redundancy requirements, to improve
power efficiency.
• The CMC reports real-time power consumption.
• The CMC supports an optional power ceiling, which will either
trigger an alert or actions to keep the enclosure power
consumption under the predefined ceiling.
• The CMC monitors and controls cooling fans based on actual
ambient and internal temperature measurements.
– The CMC provides comprehensive enclosure inventory and
status/error reporting.
– The CMC allows centralized configuration of the following settings:
• The CMC’s network and security settings
• Power redundancy and power ceiling settings
• I/O switches and iDRAC network settings
• First boot device on the blades
– The CMC will check I/O fabric consistency between the I/O modules
and blades and will disable system components if necessary to protect
the system hardware.
– User access security.
– An SD card slot on the CMC card supports an optional persistent
WWN/MAC feature that allows slot-based WWN/MACs for the
blades, simplifying blade installation and replacement.
