Prism Central, ncc check says needs more resources. 200 VMs but PC thinks it is Large?

Upgraded PC to 2020.7 and ncc to 3.10.1.  Now getting the warning:Possible CauseThe current feature capabilities of Prism Central require resource on the Prism Central VM to be increased for optimum performance. RecommendationIncrease the resource of the Prism Central VM. Please refer KB-8932 for guidance. I am at 6 vCPU and 32 GB RAM for PC VM.  Not getting too far with support.  I was wondering if others have seen this issue.The KB article mentions “large” and “small”.  I don’t remember setting PC size.  How does it know if it is large or small?  Mine thinks it is large, but I only have around 200 VMs in 3 Clusters.  Only using a single PC, not scaled.

Utilizing the cvm_shutdown Script

When performing maintenance on a CVM, it is important to not treat it as a regular guest VM. This is because there are crucial services running on each CVM which need to gracefully respond when a CVM goes offline.If you need to shutdown a CVM and are running ESXi, you might otherwise think to simply go to vCenter, right-click on the CVM, and select the “Shut Down Guest OS” option. However, that procedure will not properly shut down the CVM and allow the services to gracefully respond.Instead, in using the cvm_shutdown script, it will first place a necessary HA route in the hypervisor, to redirect storage requests to another CVM, before shutting down the CVM. This will also allow the services to gracefully respond to the CVM being offline.More information and options regarding this script can be found in KB 3270

Installing Discrete Graphics Host Drivers on AHV Hosts

Did you know that AHV hosts can be accelerated by discrete graphics hardware (similar to how home gaming systems are accelerated)? This is especially useful for environments such as Virtual Desktop Infrastructure (VDI) deployments where it is desirable to accelerate individual desktops being shared out to large user communities.The host driver for the discrete graphics hardware can be easily installed on AHV hosts via a single command as executed from just a single CVM of a Nutanix cluster (executing the command from a single CVM will install it across all of the CVMs of the cluster – no need to touch each CVM/host individually). Information regarding this single-command procedure can be found from the INSTALLING NVIDIA GRID VIRTUAL GPU MANAGER (HOST DRIVER) section of the AHV ADMINISTRATION GUIDE.Also, just to note, the host driver can be installed on hosts running an ESX hypervisor using a different procedure. That procedure can be found via the knowledge base article Install NVIDIA

Understanding Fault Domains and Rack Awareness

What is Fault Tolerance (FT)?FT is how the system ensures that both user VM data and cluster infrastructure data is protected from failure. What are Fault Domains?Failure scenarios can be thought of in terms of fault domains.  There are four fault domains in a Nutanix cluster:Disk Node Block RackThis article focusses on Rack Awareness. Rack failure can occur in the following situations:All power supplies fail within a rack Top-of-rack (TOR) switch fails Network partition; where one of the racks becomes inaccessible from other racksWhen rack fault tolerance is enabled, the cluster has rack awareness and the guest VMs can continue to run with failure of one rack (RF2) or two racks (RF3). The redundant copies of guest VM data and metadata exist on other racks when one rack fails.Note – Rack fault tolerance has to be configured manually. Requirements and configuration of Rack Fault Tolerance can be found here.To learn more about Rack Fault tolerance on Nutanix Clusters click here.Now, Rack

field installation

In the process of installing the nx-8235-g7 equipment, the foundation cannot perform IPMI MAC ADDRESS DISCOVERY.When the installation was powered on, it was booted into Phoenix.iso and the IPMI IP setting was possible, so the installation was possible with the foundation. Is there any change in IPMI MAC DISCOVERY method from G7 equipment? And when the equipment is received and powered on, it boots into Phoenix.iso. Can you know what this is?And starting from g7, is the IPMI DEFAULT PASSWORD indicated by a sticker on the back of the device where the ipmi ID/PASSWORD is not ADMIN/ADMIN?
