Which feature in Nutanix helps maintain operations when a Power Delivery Unit (PDU) fails, causing a block to power off?

Cluster Health
Block Awareness
Volume Group
NFS Whitelist

The correct answer is: Block Awareness

Block Awareness is the feature in Nutanix that assists in maintaining operations when there is a failure of a Power Delivery Unit (PDU), which can lead to a scenario where a block of nodes is powered off. This feature enables the system to recognize the specific blocks that are affected by power issues and intelligently manage workloads across the remaining operational blocks. By having awareness of block availability, Nutanix can ensure that data and applications remain accessible by redistributing workloads as necessary. This capability is essential for maintaining high availability and operational continuity, especially in environments where power management is critical. The intelligent handling of resources helps minimize downtime and maintain performance even during hardware failures or power disruptions. Other features such as Cluster Health focus more on the overall status and performance of the cluster, while Volume Group and NFS Whitelist pertain to storage configurations and access control, which do not directly address power-related issues or block-level awareness in the context of maintaining operations during a PDU failure.
