Storage Utilization

Hello, I have turned on Windows Dedup for some of my file servers that reside on AHV, however the storage reduction is not reflected on Prism. Any thoughts as to why? I wish I could run the Capacity Dedup from AHV however the last time that I turned it on I received the following alert: Do not replicate protection domain XXXXXXX comprising entities from the storage container that have deduplication enabled to a single node remote site XXXXXXX. (XXX denote omitted field)

Understanding NX GPU Solution

Let us consider a scenario where you are running specific workloads that require extensive video rendering and needs GPU-enhanced acceleration.   Nutanix provides a solution in which the hardware is configured with GPU cards that allow video rendering to be passed through to the User Virtual Machine.    Want to read about NVIDIA Grid vGPU on Nutanix?    The following guide will help in understanding the architecture and requirements of handling it.    Nvidia grid vGPU Guide    So which hypervisors support this implementation?     The following hypervisors support the implementation :     AHV  VMware vSphere   Microsoft Hyper-V    The following document lists the hypervisor implementation in-depth for a vGPU solution.    vGPU on Nutanix: Hypervisor Implementation.      Have a GPU in your NX environment but wondering regarding the configuration, drivers requirement and basic troubleshooting?   Go through the following articles to understand some basic troubleshooting steps, command

AHV VM CPU Usage consumes higher % than ESXi?

My customer reported that in their test, the CPU Usage of AHV VM always consumes 10% higher than ESXi so I am going to find out what is the most suitable reason behind this problem I have searched around and find out this blog below that having a paragraph pointing about hypervisor bottleneck: "The Nutanix Controller VM (CVM) runs on top of multiple hypervisors and delivers excellent performance, but there is always room for improvement. With our extensive experience with in-kernel and virtual machine based storage solutions, we quickly learned that the [b]biggest bottleneck is the hypervisor itself[/b]."

On the other hand, I have tested by myself on the scenario in which I have built up 2 VMs with the same configuration on 2 clusters having same Nutanix model and run the CPU tes

Hyper-V - Persistent Reservations & Corrupt VHDs

[b]How do Persistent Reservations work with Hyper-V on Nutanix?[/b] [list] [*]I'm asking because with our other "Hyper-V with SMB Storage" clusters, you are not able to use Hyper-V manager on [b]HOST1[/b] to modify VHDs that belong to a VM running on [b]HOST2[/b], as you would expect - Error reads: "Access Denied". However, with Nutanix, we are able to do this and it leads to VHD corrouption upon next reboot of the VM [*]Here is the scenario:[list] [*]Hosts: 5 node Nutanix cluster with Hyper-V (Dell XC hardware) [*]VM1 is running on HOST1 [*]Using HOST2, launch Hyper-V manager ([i]not Failover Cluster Manager).

Inter site replication traffic

Can anyone tell me if the inter-site (not intra-site, I am talking about DR replication traffic between clusters) is moved to the backplane traffic port when network segmentation is enabled? The Prism Web Console Guide v5.5 does not say so (it only mentions intra-cluster traffic): [quote]The traffic entering and leaving a Nutanix cluster can be broadly classified into the following types: [i]Backplane traffic[/i]Backplane traffic is intra-cluster traffic that is necessary for the cluster to function, and comprises traffic between CVMs, traffic between CVMs and hosts, storage traffic, and so on. (For nodes that have RDMA-enabled NICs, the CVMs use a separate RDMA LAN for Stargate-to-Stargate communications.) [i]Management traffic[/i]Management traffic is administrative traffic, or traffic associated with Prism and SSH connections, remote logging, SNMP, and so on. The current implementation simplifies the definition of management traffic to be any traffic that is not on the back

Managing a Hyper-V cluster

Let’s say you have a new NX Hyper-converged architecture and want to use Hyper-V as a hypervisor, but now you are confused regarding the initial configuration and what all are required.Questions which are hovering your mind right now !!! What are the requirements to create a Nutanix cluster with Hyper-V? How can I image the nodes with Hyper-V and install AOS? How can I manage my Hyper-V host? How can I create a failover cluster and update Hyper-V settings? How can I create and manage VMs, especially HA VMs? Do we provide a documentation which can help you answer all these queries? Yes, absolutely Give this following documentation a read to easily get started with Hyper-V.KB-2235Want to know about the configuration of Hyper-V in Nutanix in-depth? Go through this documentation guide to understand how Hyper-V gets configured in a Nutanix environment. Hyper-V configuration

Hypervisor Upgrade (ESXi) using One Click (Host Maintainance Mode issue)

Apart from listed pre-requisites before starting Hypervisor Upgrade (ESXi) listed below, had to Disable Affinity Rules under DRS to enable ESXi host go into Maintainance mode and continue update. Got stuck since i did found this part the hard way... 1) Genesis.out log pointed the target CVM owning Shutdown token and not letting it go. 2) Then from vCenter: Manual Shutdown of CVM -> Manually put related ESXi host in Maintainance mode -> Exit Maintainance mode -> Start CVM 3) Go to PRIMS and upgrade continues... and so does 2048... - Koji

Distributed object storage on Nutanix

Hi, we're starting to look at using Spark on our Nutanix cluster. Not in a huge way but to run some ETL processes in parallel. I'm under pressure to install Hadoop, or at least HDFS on the cluster but the entire concept of adding a distributed, resilient "filesystem" (actually I think it's more an object store) on top of the one already provided by Nutanix seems somewhat off. Is there a recommended way of doing this? I know that containers are exported to ESXi via NFS. Would that be usable? Would that be able to leverage stargate to access from anywhere? All I really need is a globally available volume shared between all my nodes.

Enabling or Disabling Console Support for vGPU VMs

Enable or disable console support for a VM with only one vGPU configured. Enabling console support for a VM with multiple vGPUs is not supported. By default, console support for a VM with vGPUs is disabled.To enable or disable console support for each VM with vGPUs, do the following: Run the following aCLI command to check if console support is enabled or disabled for the VM with vGPUs.acli> vm.get vm-nameWhere vm-name is the name of the VM for which you want to check the console support status.The step result includes the following parameter for the specified VM:gpu_console=FalseWhere False indicates that console support is not enabled for the VM. This parameter is displayed as True when you enable console support for the VM. The default value for gpu_console= is False since console support is disabled by default.Note: The console may not display the gpu_console parameter in the output of the vm.get command if the gpu_console parameter was not previously enabled.
