The AHV Image Service is the Nutanix feature designed for managing VM disk images (like ISOs and disk files) centrally. It acts as a repository for golden images, allowing administrators to upload images once and then deploy VMs from them across the cluster, which perfectly streamlines the process described.

High guest-visible memory usage does not necessarily mean the VM needs more configured RAM. The next critical step is to investigate guest-level behavior using Nutanix tools to see if there is memory pressure causing ballooning or swapping, which are more accurate indicators of a true memory shortage than usage alone.

Host Pin is the correct AHV feature that forces a VM to run on a specific, user-selected host and prevents it from being migrated away, even during a host reboot. Affinity/Anti-Affinity policies govern relationships between VMs or VMs and hosts, but do not pin to a single specific host.

With RF2, data is written in two copies across different nodes. This means for every 1 TB of logical data, 2 TB of raw physical space is consumed. Therefore, with 10 TB of raw space, the maximum usable capacity for user data is roughly half, or ~5 TB, before accounting for filesystem metadata and other overheads.

Curator is the background maintenance service. Its primary function is to perform tasks like garbage collection (cleaning up stale data after updates/deletes), rebalancing data across nodes for even distribution, and checking data integrity, which optimizes cluster health and performance.

Nutanix stores metadata (data about the data, crucial for performance) on the SSD tier. The ‘Metadata Offload’ alert is a critical warning that the SSD tier for that container is full, forcing metadata to spill over to the slower HDD tier. This will cause significant performance degradation for all VMs using that container.

A VM-VM Anti-Affinity Rule instructs the AHV scheduler to keep the specified VMs separated by running them on different hosts. This is the standard method to ensure VMs in an application cluster (like web servers or domain controllers) do not fail together if a single host goes down.

The Nutanix cluster is self-healing and autonomous. After adding a node, the cluster will automatically absorb it into the storage pool. The Curator service will subsequently run its normal scheduled tasks to rebalance data across all nodes, including the new one, without requiring manual intervention.

Prism Element is the local management interface for a single Nutanix cluster. Prism Central is a multi-cluster management solution that provides a single pane of glass for managing, monitoring, and orchestrating operations across multiple Nutanix clusters, whether on-premises or in different locations.
