CMC features

The CMC provides the following multiple systems management functions:
  • Enclosure-level real-time automatic power and thermal management:
    • Monitors system power requirements.
    • Reports real-time power consumption, which includes logging high and low points with a time stamp.
    • Supports setting an optional enclosure Maximum Power Limit, which either alerts or takes actions, such as throttling compute sleds and/or preventing the power up of new compute sleds to keep the enclosure under the defined maximum power limit.
    • Monitors and automatically controls cooling fans based on actual ambient and internal temperature measurements.
    • Provides comprehensive enclosure inventory and status or error reporting.
  • Centralized configuration of the following:
    • The enclosure’s network and security settings.
    • Power redundancy and power ceiling settings.
      NOTE: Modifying the modular enclosure redundancy policy is recommended to be performed while the modular enclosure is powered off.
    • I/O module and iDRAC network settings.
    • First boot device on the compute sleds.
    • Checks I/O path consistency for the I/O module, PCIe slots, and sleds and disables components if necessary to protect the system hardware.
    • User access security.
The CMC module is hot-swappable. During the period that the CMC module is removed:

  • you cannot turn on newly installed compute sleds

  • existing compute sleds cannot be accessed remotely

  • enclosure cooling fans run at maximum speed for thermal protection of the components
