ESXi clusters require vCenter Server for management, which integrates with Prism Element for unified infrastructure management.

Chronos is the job scheduler that manages and coordinates background tasks like snapshots, replication, and maintenance operations.

NCC checks hardware health, software versions, and configuration compliance but does not monitor guest OS within VMs.

First identify which CVM has high memory, check what processes are consuming memory, review service logs for errors, then take corrective action.

Navigate to Settings, access Syslog configuration, add remote syslog server details (IP, port, protocol), and test the connection.

High CPU ready time indicates VMs are waiting for CPU resources to become available, suggesting the host is oversubscribed.

Critical hardware failures, high capacity utilization, and node/CVM offline conditions require immediate investigation, while informational alerts do not.

Start by creating the VM object, configure CPU and memory resources, attach virtual disks, and configure network adapters.

Predictive disk failure alerts should be reported to support with the disk serial number so replacement can be coordinated before actual failure.

Start by checking storage latency during boot, verify the boot device configuration, analyze CPU and memory resources, and check network dependencies.

Syslog uses UDP port 514 by default, requiring firewall rules to allow traffic from cluster to the syslog server.

Alert reminder configuration allows repeated notifications at specified intervals until the alert is acknowledged or resolved.

Anti-affinity rules ensure that specified VMs (like redundant application servers) run on different hosts for better availability.

AOS updates use a rolling upgrade process where CVMs are updated one at a time, allowing the cluster to remain operational.

Access LCM interface, verify current framework version, download the latest framework update, and install it before updating other components.

The “Outdated“ status in LCM inventory shows that the installed version is older than the currently available release version.

RF2 with Erasure Coding (EC-X) provides the best balance of data protection and capacity efficiency, reducing overhead from 50% to approximately 25-33%.

Genesis is the master service that bootstraps cluster formation, coordinates services, and manages cluster-wide operations and state.

Navigate to the Reports section, select configuration report type, choose which components to include, and generate the report for download.

Select the target container, enable the deduplication feature, configure when deduplication scans run, and monitor the results and capacity savings.

License information including edition type and active features is found in Prism Settings under the Licensing section.

Erasure Coding (EC-X) converts replicated data to a parity-based scheme, reducing storage overhead while maintaining data protection.

Compression is highly effective for sequential workloads as it processes data streams efficiently without the overhead of deduplication fingerprinting.

Pithos is the distributed storage fabric layer that manages vDisks, snapshots, and clones across the cluster.

Alert policies define the complete configuration including triggers, conditions, severity, and actions that determine when and how notifications are sent.

Cassandra is a distributed database that stores cluster configuration, metadata, and state information across all CVMs in the cluster.

Before removing a node, verify the cluster will maintain required capacity and replication factor to ensure data protection and performance.

A minimum of one SSD per node is required in hybrid configurations to provide the performance tier for hot data and metadata.

Nutanix Move is specifically designed to migrate VMs from various sources including VMware, Hyper-V, and AWS to Nutanix AHV.

Navigate to Settings, access SNMP configuration, add SNMP trap destination addresses, and test the configuration to verify connectivity.

Dark Site mode requires administrators to manually download update packages to a local repository for deployment in air-gapped environments.

Critical alerts typically require manual acknowledgment by administrators to ensure they have been reviewed and addressed.

A witness is a lightweight VM or physical server at a third site that provides quorum to prevent split-brain scenarios in stretched cluster configurations.

When a CVM is down, VMs on that node lose local storage I/O path and must access storage through other CVMs over the network until recovered.

Stargate, Curator, and Prism are core CVM services, while VMkernel is a hypervisor component that runs on ESXi hosts, not CVMs.

Both VMware ESXi and AHV support hot-add capabilities for CPU and memory, though it must be enabled in VM configuration before use.

Select the target container, view its properties, increase the capacity limit or mark it unlimited, and apply the changes.

First investigate what is consuming space in the container (large VMs, snapshots, etc.) before taking corrective action.

Select the desired recovery point snapshot, activate the protection domain at the recovery site, power on recovered VMs, and test connectivity.

The “Staged“ status shows that update packages have been downloaded and pre-checked but not yet applied to the cluster.

Shadow Clones are most effective when many VMs frequently read the same data blocks, creating opportunity for shared read cache.
