Nutanix NCP-EUC Exam With Confidence Using Practice Dumps

The performance issue is caused by Host CPU overcommitment, specifically regarding CPU scheduling (Ready Time) rather than total utilization.

While the Host CPU utilization is below 80% (meaning the processor has idle cycles), the configuration of 8 vCPUs per VM combined with a high 9:1 vCPU-to-pCPU ratio creates a bottleneck known as "Co-stop" or high "CPU Ready" time. The hypervisor scheduler must wait until 8 physical cores are available simultaneously to execute a single clock cycle for one VM. In a dense VDI environment, finding 8 free cores at the exact same moment is difficult, causing the VMs to pause (freeze) while waiting for the scheduler, even if the overall CPU usage of the host appears moderate. Reducing the vCPU count per VM would likely resolve the performance issues.

Blast Extreme is the proprietary display protocol developed by Omnissa (formerly VMware) for Horizon.

A key feature of Blast Extreme is its use of Adaptive Transport. This technology allows the protocol to dynamically switch between UDP (for high performance and lossy networks) and TCP (as a fallback for reliability) based on real-time network conditions. This adaptability ensures the best possible user experience regardless of bandwidth or latency constraints. (PCoIP primarily relies on UDP, and RDP is traditionally TCP-heavy, while HDX is a Citrix protocol).

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.
