Reference Guide

The CIM_DMA class described in DMA Properties contains DMA information. A DMA channel allows certain types of data transfer
between RAM and a device to bypass the microprocessor.
The following table describes the property, description, and data type details for CIM DMA.

Availability Availability of the DMA. Availability values are
dened as follows:
• 1 - Other
• 2 - Unknown
• 3 - Available

CIM_RedundancyGroup
The CIM_RedundancyGroup class described in Table properties below is a set of components that provide more instances of a critical
component than are required for the system’s operation. The extra components are used in case of critical component failure. For example,
multiple power supplies allow a working power supply to take over when another power supply has failed.
The following table describes the property, description, and data type details for the CIM RedundancyGroup.
