1OverviewThe Dell Chassis Management Controller (CMC) for Dell EMC PowerEdge VRTX is a Systems Management hardware and softwaresolution for managing the PowerEdge VRTX chassis. The CMC has its own microprocessor and memory and is powered by themodular chassis into which it is plugged.CMC enables an IT administrator to:• View inventory• Perform configuration and monitoring tasks• Remotely turn on and turn off chassis and servers• Enable alerts for events on servers and components in the server module• View and manage storage controller and hard disk drives in the VRTX chassis• Manage the PCIe subsystem in the VRTX chassis• Provide a one–many management interface to the iDRACs and I/O modules in the chassisYou can configure the PowerEdge VRTX chassis either with a single CMC, or with redundant CMCs. In redundant CMCconfigurations, if the primary CMC loses communication with the chassis or the management network, a standby CMC takes overthe chassis management.CMC provides multiple System Management functions for servers. Power and thermal management are the primary functions ofCMC, which are listed as follows:• Enclosure-level real-time automatic power and thermal management.– CMC monitors system power requirements and supports the optional Dynamic Power Supply Engagement (DPSE) mode.This mode enables CMC to improve power efficiency by setting the power supplies while the server in standby mode anddynamically managing the load and redundancy requirements.– CMC reports real-time power consumption, which includes logging high and low points with a time stamp.– CMC supports setting an optional enclosure maximum power limit (System Input Power Cap), which alerts and takes actionssuch as limiting the power consumption of servers, and/or preventing the turning on of new servers to keep the enclosureunder the defined maximum power limit.– CMC monitors and automatically controls the functions of cooling fans and blowers on the basis of actual ambient andinternal temperature measurements.– CMC provides comprehensive enclosure inventory and status or error reporting.• CMC provides a mechanism for centralized configuration of the:– Network and security setting of the Dell PowerEdge VRTX enclosure.– Power redundancy and power ceiling settings.– I/O switch and iDRAC network settings.– First boot device on the server module.– I/O fabric consistency checks between the I/O module and servers. CMC also disables components, if required, to protectthe system hardware.– User access security.– Storage components, including the fault-tolerant mode for the storage controllers.– PCIe slots.You can configure CMC to send email alerts or SNMP trap alerts for warnings or errors such as temperature, hardwaremisconfiguration, power outage, fan speed, and blowers.14
