The minimum hardware requirement for each domain controller to support Microsoft Defender for Identity installation specifies that a domain controller should have at least two cores and 6 GB of RAM. This requirement ensures that the system has enough processing power and memory to handle the operations of Microsoft Defender for Identity, which analyzes and processes security data from Active Directory environments.
The specified hardware configuration allows for efficient processing of security analytics and detection tasks performed by the Defender for Identity solution. As security workloads can be resource-intensive, having a minimum of two cores allows the domain controller to run multiple processes simultaneously, while 6 GB of RAM provides sufficient memory for the application to function effectively without performance degradation.
In contrast, the other requirements mentioned, such as having multiple network adapters, a very large amount of disk space, or enabling dynamic memory allocation, are not part of the basic hardware specifications for running Microsoft Defender for Identity. These considerations might apply to specific configurations or performance enhancements in more complex environments but are not fundamental to the initial setup.
