gpumodeswitch is a command-line tool that is used to switch supported NVIDIA GPUs between compute and graphics mode. Compute mode allows multiple VMs to share a GPU for CUDA workloads. Graphics mode allows a single VM to use a GPU for graphics workloads12.

The CPU usage percentage indicates how much of the allocated CPU resources the virtual desktop is consuming.
A high CPU usage percentage means that the virtual desktop is using a lot of CPU resources, which can affect the performance of other virtual desktops on the same host or cluster.
According to Nutanix best practices, the recommended CPU usage percentage for virtual desktops is less than
80%.
* VM-0001 (99%)
* VM-0002 (98%)
* VM-0003 (97%)
* VM-0004 (96%)
* VM-0005 (95%)
* VM-0010 (85%)
* VM-0016 (81%)
These virtual desktops are likely contributing to the performance issue by consuming too much CPU resources and starving other virtual desktops from performing adequately.

the delivery method in use is Citrix MCS. Citrix Machine Creation Services (MCS) is a technology that creates and manages virtual machines from a master image. MCS uses Nutanix storage efficiency features such as deduplication and shadow clones to reduce storage consumption and improve performance. The exhibit shows that the VDI cluster has a high deduplication ratio (7.5x) and a low physical space usage (1.2 TB) compared to the logical space usage (9.1 TB), which indicates that MCS is in use.

For persistent desktop workloads (full clones) where data efficiency is critical, Nutanix recommends leveraging Inline Compression as the primary reduction technology. To further optimize storage capacity without the heavy memory overhead associated with Deduplication, the recommended complementary technology is Erasure Coding (specifically Inline Erasure Coding in newer AOS versions or EC-X post- process).
Erasure Coding increases the effective usable capacity of the cluster by stripping data parity across nodes (similar to RAID 5/6 logic) rather than relying on the default Replication Factor 2 (RAID 1 logic) for cold or write-cold data. Since persistent desktops often contain large amounts of static data after the initial OS and application installation, Erasure Coding significantly reduces the storage footprint. While Capacity Deduplication (Option D) is available, it is generally reserved for specific use cases (like full clone setups with high data commonality) due to its high RAM requirement for fingerprint metadata, making Erasure Coding the more universally applicable "other" technology for general persistent VDI.

In a Nutanix-hosted Citrix Virtual Apps and Desktops environment, proper network port configuration is essential for component communication. The Citrix License Server is a critical infrastructure component that manages product licensing.
According to Nutanix Validated Designs and Citrix reference architectures for traffic flow, TCP port 27000 is the default port required for inbound communication to the License Server. This port is used by the License Server Manager (lmadmin or lmgrd) to receive communication from Citrix products (such as the Delivery Controller) requesting licenses.
The specific port breakdown for the License Server is:
* Port 27000 (TCP): The License Server Manager port (Inbound communication). This is the primary entry point.
* Port 7279 (TCP): The Vendor Daemon port.
* Port 8082/8083 (TCP): The Administration Console web port (used for management, not licensing requests).
Therefore, to ensure successful inbound communication for licensing operations within the Nutanix infrastructure, the firewall must allow traffic on Port 27000.
