The CVM’s primary storage port (eth0) is specifically designed for storage traffic (iStor/iSCSI and data services). Isolating this traffic on a dedicated network, as per best practices, improves performance and security by separating it from management and VM client traffic.

Prism Central is the multi-cluster management plane. For an image to be available across multiple clusters managed by the same Prism Central, it must be uploaded to the Prism Central instance. Uploading to a local Prism Element only makes it available to that single cluster.

vCPU Pinning binds a VM’s virtual CPUs to specific physical CPU cores on the host. This guarantees those cores are dedicated to that VM, preventing other VMs from using them and ensuring immediate, consistent compute performance regardless of host load, which is crucial for low-latency applications.

Metadata Offload is a performance feature where metadata I/O is served from SSD. If it’s disabled, metadata operations fall back to the storage pool’s persistent storage (often HDD), which is significantly slower. This directly impacts the performance of write-heavy workloads that frequently update metadata.

Placing the node into Maintenance Mode is the critical first step. This triggers the Nutanix Controller VM (CVM) to gracefully hand off its responsibilities, migrate its data to other nodes in the cluster via Curator, and allows AHV to live-migrate VMs off the host automatically, ensuring a safe and non-disruptive process.

Dynamic Categories allow administrators to define rules (e.g., ‘Description contains Sales’) that automatically assign VMs to categories. This is more scalable and accurate than manual, static assignment, especially in large environments where VMs are created frequently.

For a VLAN-backed network in AHV to function, the physical switch port connected to the host’s NIC must be configured as a trunk port that allows that specific VLAN ID. If the VLAN is not trunked, the tagged traffic from the VM will be dropped at the physical switch, preventing communication.

ADSF is the core of Nutanix HCI. It distributes storage resources and intelligence across all nodes in the cluster, creating a shared-nothing architecture. This fundamentally removes the traditional external SAN/NAS array and its associated network, which are common points of failure and performance bottlenecks.

Prism Central’s role-based access control (RBAC) allows the creation of custom roles with very granular permissions. By creating a role with permissions limited to VM and application operations (not infrastructure), and assigning users with that role to a specific Project, you achieve secure, delegated administration.
