The Integrated Dell Remote Access Controller (iDRAC) is the component within a PowerFlex cluster that provides server metrics, including telemetry and thermal data, and allows for setting the server configuration profile. iDRAC is an embedded system management hardware and software solution that provides remote management capabilities, system health monitoring, and recovery capabilities. It is a key component for server lifecycle management within the PowerFlex infrastructure1.

iDRAC operates independently from the server’s CPU and operating system, enabling administrators to monitor server health and manage systems even when the server is turned off or unresponsive. It provides a comprehensive set of server management features, including:

• Monitoring server health and managing power usage.
• Accessing logs for troubleshooting and recovery.
• Updating firmware and drivers.
• Configuring hardware settings and server profiles.

These capabilities are essential for maintaining the reliability and performance of PowerFlex clusters, making iDRAC a critical component for server metrics and configuration management.

In a PowerFlex system, the SCLI (ScaleIO Command Line Interface) commands are typically performed on the Primary MDM (Metadata Manager). The Primary MDM is responsible for the overall management and operation of the cluster, including configuration changes and monitoring1. It is the authoritative source for metadata and cluster configuration, making it the primary point of interaction for administrative tasks.

The Tie-breaker and Standby MDMs serve as part of the high availability setup. The Tie-breaker MDM is used to avoid split-brain scenarios, and the Standby MDM is a backup that can take over the role of the Primary MDM if it fails. The Secondary MDM works in conjunction with the Primary MDM to manage the cluster but does not serve as the main point for executing SCLI commands.

Therefore, the correct answer is C. Primary, as it is the MDM where SCLI commands are executed for monitoring and managing the PowerFlex cluster.

The maximum raw capacity that can be expected in a 1U Node while configuring a PowerFlex system with an MG (Multi-Granularity) pool is 38.4 TB. This is based on the typical maximum raw storage capacity available for a 1U node configuration, which is designed to fit within the physical constraints of a 1U rack space while providing a balance of capacity and performance1.

The MG pool in PowerFlex is designed to optimize storage efficiency and performance, and the capacity of a 1U node would be aligned with the specifications that ensure the system’s reliability and scalability. The other options listed provide capacities that are generally too high for a single 1U node within the PowerFlex architecture1.

Therefore, the correct answer is A. 38.4 TB, as it represents the realistic maximum raw capacity for a 1U Node in a PowerFlex system with an MG pool.
