According to Nutanix Flow Network Security Guide:

Policy States: Security policies in Nutanix Flow have two primary operating modes: Monitor and Enforce.

Monitor Mode: In Monitor Mode (Option A), the policy rules are evaluated, and traffic that would have been blocked is logged, but the traffic is allowed to pass.

Use Case: This is explicitly designed for the scenario described: "testing the impact... before enforcing." It allows the administrator to visualize the flow logs (via the Visualizer) to ensure no legitimate traffic would be dropped, before switching the toggle to Enforce Mode (Option B) which actually blocks the traffic.

According to Nutanix and Microsoft Best Practices for Non-Persistent VDI images:

Policy Setting: The Group Policy setting "Allow Automatic Updates immediate installation" should be set to Disabled.

Reasoning: In a non-persistent environment, desktops revert to their base state upon reboot. Allowing automatic updates to install immediately during a user session consumes system resources (CPU/IOPS) and any changes made are discarded when the user logs off and the VM reboots.

Correct Management: Updates should be applied solely to the Master/Gold Image during a maintenance window. Once the master image is updated and sealed, it is redeployed to the pool. Disabling immediate installation prevents the "Windows Update" service from attempting to patch transient clones unnecessarily.

To calculate the estimated number of virtual desktops per server, one must consider the physical memory of the GPU, the memory required by the selected vGPU profile, and the number of GPUs installed in the node.

GPU Specifications: The NVIDIA L40S GPU is equipped with 48 GB of physical GDDR6 memory.

Profile Requirements: The L40S-12Q profile allocates 12 GB of frame buffer memory to each virtual desktop.

Density Calculation per GPU: Dividing the total physical memory by the profile memory (48 GB / 12 GB) results in 4 virtual desktops supported per single GPU card.

Server Capacity: The Nutanix NX-9151-G9 platform supports up to four NVIDIA L40S GPUs per node.

Total Estimate: Multiplying the desktops per GPU by the number of GPUs (4 desktops x 4 GPUs) yields a total of 16 virtual desktops per server.

roaming profiles are a way to deliver user settings across physical and virtual desktops. However, they can also cause issues such as profile unload failures2 and slow log-on and log-off times1.

The file server VM (FSVM) is a virtual machine that runs on Nutanix Files and provides file services such as SMB shares and NFS exports. The FSVM is based on CentOS and incorporates all the security and hardening that goes into the Nutanix Controller VM (CVM)2. The CVM is a virtual machine that runs on each node of a Nutanix cluster and provides storage management, data protection, cluster coordination, and other services3.

The FSVMs have some default configuration settings that can be changed depending on your workload requirements. For example, you can change the number of vCPUs, RAM, network interfaces, or disk size of an FSVM2. However, you should not change these settings without consulting Nutanix Support first.

One of the factors that affects the performance of an FSVM is its memory allocation. The more memory an FSVM has, the more cache it can use for file operations. This can improve the throughput and latency of file serving workloads4. Therefore, increasing the FSVM RAM to 96GB can help optimize its performance for a large number of users.

In Nutanix Prism Central, the Capacity Runway scenario provides details on the available capacity for the next 12 months based on the current usage pattern. This feature can help the administrator to plan and prepare the budget for the next fiscal year. The administrator can use this information to decide whether more resources need to be added to the Nutanix cluster or if the existing resources are sufficient.

Prism Central planning tools can help you estimate the capacity runway of your cluster by considering the storage, CPU, and memory capacity. However, you need to have at least 21 days of data from a cluster to calculate the baseline runway estimates4.

In a non-persistent VDI environment, changes to the operating system should only occur within the Golden Image (or Master Image), not on the individual provisioned VMs. If the Windows Update policy is set to Automatic within the Gold Image, the clones generated from that image will independently check for updates, download them, and attempt to install them during the user's session.

This behavior often triggers a "Restart Required" prompt to the end-user to finish installing the updates. To prevent this disruption and ensure version consistency, Nutanix and VDI best practices dictate that the Windows Update service should be disabled or set to Manual in the Gold Image. Updates should be applied administratively to the Gold Image during a maintenance window, followed by a recompose/update of the machine catalog.

one of the possible Nutanix storage efficiency features that the administrator can use for this solution is Deduplication. Deduplication is a technology that eliminates duplicate blocks of data and reduces storage consumption. Deduplication can be enabled on a per-container basis and can provide significant savings for Citrix virtual desktop deployments that use cloning technologies such as Machine Creation Services (MCS) or Provisioning Services (PVS)1.
