CMC for PowerEdge VRTX Features Enabled by Digital Licensing
8
Chassis Grouping
The Chassis Grouping feature helps conveniently manage multiple VRTX chassis in the same
environment. Chassis can be assigned to a Chassis Group. You can assign the chassis to a Chassis
Group and administer it through Multi-Chassis management. In this configuration, one chassis is
assigned the ‘lead’ role, while the other in the same group is assigned the ‘member’ role. Only the
lead chassis has access to the information about a member chassis.
Enclosure Backup
The Enclosure Backup feature allows you to make a backup copy of the CMC and chassis
configuration settings on the file system of your remote client workstation. The enclosure backup
will save information and settings about the overall chassis, including network settings, security
certificates, user configuration, and power policy. The enclosure backup also contains slot
information, such as slot name and FlexAddress settings. Server-specific information is not saved.
The enclosure backup does not include the CMC firmware image. The backup file is encrypted and
keyed to this chassis so it cannot be loaded on to another chassis.
FlexAddress Enablement
The FlexAddress Enablement features are optional upgrades that allow the CMC to assign WWN/MAC
(World Wide Name/Media Access Control) addresses to Fiber Channel and Ethernet devices. Chassis
assigned WWN/MAC addresses are globally unique and specific to a server slot within a given chassis.
FlexAddress allows the CMC to assign the WWN/MAC address (Chassis Assigned IDs) that stays with a
particular slot in the chassis.
If a server is replaced, the FlexAddress for the slot remains the same for the given server slot. If the
server is inserted in a new slot or chassis, the server-assigned WWN/MAC is used unless that chassis
has the FlexAddress feature enabled for the new slot. If you remove the server, it will revert to the
server-assigned address. You need not reconfigure deployment frameworks, DHCP servers, and
routers for various fabrics for identifying the new server.
Dynamic Power Supply Engagement
Dynamic Power Supply Engagement (DPSE) mode, the power supplies are turned on or turned off on
the basis of power consumption, optimizing the energy consumption for the entire chassis.
For example:
• Your power budget is 1050 Watt
• Redundancy policy is set to AC redundancy mode
• Four power supply units (PSUs) are installed
CMC determines that one of the PSUs is required to support the current power requirements, a
second is required to support the AC redundancy policy, and the others remain in standby mode.
However, if up to an additional 1050 Watt of power is required for the newly-installed servers, the
