This article explains the cause and resolution of alerts related to the Baseboard Management Controller (BMC), also known as iDRAC on Dell PowerEdge-based platforms. The BMC is an embedded controller that monitors system health parameters such as temperature, fan speeds, power status, and voltage. When the BMC becomes unresponsive or fails, the Data Domain system generates an alert.

Interface groups can be used to control the interfaces used for DD Boost MFR, to direct the replication connection over a specific network, and to use multiple network interfaces with high bandwidth and reliability for failover conditions. All protection
system IP types are supported—IPv4 or IPv6, Alias IP/VLAN IP, and LACP/failover aggregation.

Introduced in DDOS 7.5 and DDMC in 7.11, multifactor authentication adds an extra layer of security on the protection system. It requires the security officer and system administrator to enter an RSA SecurID passcode before certain destructive commands or configuration changes are allowed.
The Multifactor Authentication panel allows the user to configure, enable, and disable multifactor authentication.

About interface groups: This feature lets you combine multiple Ethernet links into a group and register only one interface on the protection system with the backup application. The DD Boost Library negotiates with the system to obtain the best interface to send data. Load balancing provides higher physical throughput to the system.
Configuring an interface group creates a private network within the system, consisted of the IP addresses designated as a group. Clients are assigned to a single group, and the group interface uses load balancing to improve data transfer performance and increase reliability.
