Newly Released Nutanix NCSE-Core Exam PDF

Nutanix ABS (Acropolis Block Services) is used in the certified configuration for Oracle Linux and Oracle VM via iSCSI. ABS allows external servers to leverage Nutanix’s distributed storage by presenting Nutanix storage as iSCSI LUNs.

This feature enables Oracle workloads to benefit from Nutanix’s high-performance and resilient storage infrastructure while maintaining compatibility with Oracle’s storage requirements.

In addition to the total number of physical CPU cores, the cost of Capacity Based Licensing for a Nutanix Cluster is calculated using the RAW total storage in TiB. This approach ensures that both computational and storage resources are accounted for when determining the licensing costs.

Physical CPU Cores: The number of physical CPU cores is the primary factor in the licensing cost calculation.

Raw Total Storage: This includes the total raw capacity of all storage devices (both SSDs and HDDs) present in the cluster, measured in tebibytes (TiB).

Field Advisories Notification Setup.

The status shown in the exhibit within the Hardware Diagram section indicates a critical hardware issue that needs immediate attention.

Reseat Disks/Nodes: While reseating might help with connectivity issues, it should be performed with caution and typically after consulting support to avoid data loss or further complications.

Resolve Alerts and Re-import Disks: This step is useful but secondary to ensuring that applications are not negatively impacted. Immediate action should focus on stability and minimizing downtime.

Restart CVMs: Restarting CVMs might help but could also disrupt services and should be a last resort after consulting with support.

Application Status and Support: Checking the status of applications ensures that any critical services are not interrupted, and calling support provides access to Nutanix's expertise to address the hardware issue effectively.

Given the critical nature of hardware issues and the potential impact on the cluster, contacting support while checking the application status is the best course of action to ensure a safe and effective resolution.
