Capacity Runway in Prism Central calculates the "Runway" (time remaining before resource exhaustion) based on the consumption of User VMs running on the cluster.

If a cluster is configured with Storage-Only nodes (often used for dedicated Nutanix Files/Unified Storage deployments for profiles), the AHV scheduler is configured to prevent user VMs from running on these nodes (reserving resources strictly for CVMs and storage services). Since there are no general compute workloads (User VMs) consuming CPU/RAM, the Capacity Runway algorithm has no relevant "Guest VM" consumption data to analyze, resulting in the CPU and Memory fields being blank or not displayed, while Storage capacity might still be visible.

In Nutanix AHV networking, the default bond mode for a virtual switch is Active-Backup. In this mode, all traffic flows through a single active physical uplink, while other uplinks remain in standby mode to be used only in the event of a failure. This explains the observation that "only one of the physical NICs... is carrying VM traffic."

To utilize multiple physical uplinks simultaneously and balance the traffic, the administrator must change the bond mode to an Active-Active configuration. In AHV, this is achieved by configuring the bond mode to Balance-SLB (Source Load Balancing) or Balance-TCP (LACP). These modes distribute VM traffic across all available physical interfaces in the bond, thereby balancing the load.

vCenter can execute approximately 640 concurrent operations before incoming requests are queued, and can support up to 2,000 concurrent sessions1. VMware Horizon 8 can support up to 120,000 active sessions in a Cloud Pod Architecture pod federation23. Therefore, if the environment has 10,000 virtual desktops, one vCenter instance might not be enough to handle all the operations and sessions efficiently. The recommended number of vCenter instances in this configuration is B (2).

Nutanix offers a solution that delivers virtual apps and desktops in one click. Nutanix supports both persistent and non-persistent VDI deployments, as well as RDSH-based VMs and AppStacks.

Storage containers are logical units that group vDisks and apply storage policies such as replication factor, encryption, compression, deduplication and erasure coding3. Nutanix recommends using compression and deduplication to reduce storage usage and avoid duplicate data4.

A gold image is a master image that contains the operating system, drivers, patches, and configurations for a virtual desktop. A non-persistent Citrix MCS environment is one where virtual desktops are created from a gold image and discarded after each user session.

Citrix Machine Creation Services (MCS) is a tool that uses a gold image to create and manage virtual machines for Citrix Virtual Apps and Desktops environments. MCS can create different types of machines, such as pooled random, static assigned, or dedicated2.

One of the challenges of using MCS is managing multiple gold images for different user groups or application needs. Updating multiple gold images can be time-consuming and error-prone. Therefore, it is recommended to use a single base image without any applications and leverage another tool such as Microsoft System Center Configuration Manager (SCCM) to deliver applications dynamically to the cloned virtual desktops3.

This approach can simplify image management, reduce storage consumption, improve performance, and enhance user experience. SCCM can also provide additional features such as patch management, compliance enforcement, inventory reporting, etc.3

According to Nutanix Move and Citrix/VDI Master Image Preparation guides:

The Process: When Nutanix Move migrates a VM from ESXi to AHV, it installs Nutanix Guest Tools (NGT) (including VirtIO drivers) on the target VM to ensure it boots and functions correctly on the AHV hypervisor.

The Issue: If this migrated VM is intended to be a Base Image (Gold Image) for a non-persistent pool (MCS/PVS), the NGT instance installed by Move contains specific identity information (VM UUIDs/communication certificates) unique to that single VM.

The Requirement: If you clone this image without cleaning up, every clone will attempt to use the same NGT identity, causing communication conflicts with the cluster.

The Solution: The administrator must Remove NGT (or run the NGT cleanup interaction) after the conversion (once the VM is on AHV) and before reprovisioning (before sealing the image and creating clones). This ensures the clones can register as unique entities.

Citrix NetScaler VPX is a virtual appliance that provides web and application load balancing, secure and remote access, acceleration, security and offload features1. To set up and configure a Citrix NetScaler VPX appliance, you need to download it from the Citrix website, install it on a hypervisor such as Citrix XenServer or Microsoft Azure23, and log on to the console using the nsroot credentials2.

To expose the Citrix NetScaler VPX private VIP to the internet in order for users to be able to access the Citrix VDI desktops upon a DR failover, one possible solution is to use a floating IP address. A floating IP address is an IP address that can be dynamically assigned to an instance by using API calls. It allows you to redirect network traffic from one instance to another without changing any DNS settings or client configuration.

The default load balancing configuration in Nutanix AHV is Balance-SLB (Source Load Balancing). This setting utilizes all available uplinks by assigning VM traffic to specific uplinks based on source MAC address hashing. To optimize bandwidth usage, the Balance-SLB algorithm periodically evaluates link utilization and may rebalance traffic by moving a VM's assignment from one uplink to another.

According to Nutanix AHV Networking documentation, this rebalancing action involves sending a gratuitous ARP (RARP) to update the physical switch. During this split-second transition, real-time sensitive traffic—such as streaming video or VoIP—may experience dropped packets or out-of-order delivery, resulting in symptoms like "hung/frozen display frames." For environments prioritizing connection consistency over aggregate bandwidth for single VMs (like VDI with streaming requirements), Active-Backup is often recommended to eliminate the potential for rebalancing interruptions. (Note: Option A is a VMware ESXi terminology, not AHV).

According to the Prism Central Admin Guide regarding Security and User Management:

RBAC Definition: Role-Based Access Control (RBAC) is the specific feature designed to map users and groups (such as an Active Directory "Department" group) to specific sets of permissions (Roles).

Application: An administrator can define a role (e.g., "HR Admin") with specific privileges and assign it to the "HR Department" AD group. This ensures that permissions are granted granularly based on the department, fulfilling the security requirement efficiently.

Why not others:

Network Segmentation controls traffic flow (who can talk to whom), not administrative permissions.

Cluster Lockdown disables password authentication for SSH, which is a hardening step, not a permission management strategy.
