HI Expert, Can some one share  me link to where i can find nutanix IaaS with low latency solution. We wanted to show to our one of our important client.please help me with link/PPT/PDF  Thx - Sudhir 

I am trying to migrate the VM’s for Nutanix ESXi cluster to Nutanix AHV cluster but in the environment its not listing. but when i tried to migrate from Non Nutanix ESXi to Nutanix AHV and Nutanix Cluster, the VM’s are getting migrated successfully.

Things won’t always go to plan and the worst will happen. In this case, we lose 2 nodes from our 9 node rf2 cluster (e.g. one’s down for maintenance, someone forgets and reboots another node at the same time).  Can someone point me at some documentation that outlines how we can recover from this and get the cluster back up and running. Is there any permanent fallout?Thanks. 

What are the different AOS License options for enabling Data at Rest Encryption.

I need this type of solution two VM on different node in same cluster using same storage  on both VMs

we are using a two node cluster connected with a witness VM, issue is we are facing a downtime of 5 minutes because of transfer of windows vm from failure node to healthy node. we don't want any downtime because we are running Product Of Sell (POS) services in windows. we need seamless solution (e.g without breaking continuous ping).we don't want migration the issue is when the Vm is running on node A and node A fails, it took 5 minutes to start Vm on node B in failover condition ,so it create downtime we don't want this downtime.

While getting some stats for a vm the behavior seems to be different depending on the stat.Is there any documentation for specific stats? Sample Call:metrics: controller_avg_read_io_size_kbytes,controller_avg_io_latency_usecsstartTimeInUsecs: 1631290740000000intervalInSecs: 3600Output (see below):stat controller_avg_io_latency_usecs - give the expected output of a value for each interval since the input start timebut for stat controller_avg_read_io_size_kbytes - A single value is returned. What is the meaning of single value? Is it just the read at that point in time? Or is any calculation done behind the scenes? { "statsSpecificResponses": [ { "successful": true, "message": null, "startTimeInUsecs": 1632404100000000, "intervalInSecs": 3600, "metric": "controller_avg_read_io_size_kbytes", "values": [ 127 ] }, { "successful": true, "message": null, "startTimeInUsecs": 1631290740000000, "intervalInSecs": 3600, "

Hello, I have a 3 node cluster with RF 2 configured. When All the nodes are up and running I can see Total Cluster resources as below on the Prism Element.CPU - 388 Ghz RAM - 4.5 TB ( 1.5 TB Per Node) Storage - 32.9 TB  Let’s say If 1 node fails, Will my Available Storage size reduce? Please Help me. Also, I don’t understand one thing, I have Total 42 SSD of 1.92 TB = 80.64 TB, But in reality with RF2 why am I getting only 32.9 TB (without any data efficiency options enabled). I should Ideally get 40 TB of usable space. I checked on the storage sizer portal and it said I should get 63 TB. Please guide guys, what am I missing.

While trying to get the list of vms using the rest api v2 against a Hyper-V configurationThe api return the following error message  "Exception while retrieving entities : Hypervisor hyperv not supported" https://www.nutanix.dev/reference/prism_element/v2/api/vms/get-vms-getvmsThere is no mention of api v2 not supporting this, is it meant to be supported? If not how can we get the list of vms from it? Do we need to revert back to V1 api? This one returns the vm list but looking at the v1 v2 documentation the recommendation is to migrate to v2, so would just like some clarification.Also if we need to go back to V1 for hyper-v will any of the endpoints for in api V2 that require a VM_uuid work for a vm hyper-v or not? Since those uuid were returned by the V1 apiFor example:https://www.nutanix.dev/reference/prism_element/v2/api/flr/get-flr-vm-uuid-attached-disks-getattachedflrsnapshotofvmhttps://www.nutanix.dev/reference/prism_element/v2/api/flr/get-flr-vm-uuid-snapshots-getflrsnapshotsof

Difference between Cluster and I/O latency? Is that same or different?

Digital transformation demands that IT services become more agile, shorten application deployment time and increase scalability. Designed to run any application, Nutanix software converges storage and computation, eliminating the complexity of separate standalone storage solutions.

Although Prism is user friendly, it will be nice to know some commands that are useful for cluster management.   Cluster status The cluster status or “cs | grep -v UP” command gives the status(up or down ) of all the CVMs and their services. Running this command is helpful when there are alerts in the prism about services being down on certain CVMs.   Metadata ring The command “nodetool -h0 ring” shows if all the CVMs are a part of the metadata ring. Being in a metadata ring is essential for the CVM to be an active part of the cluster and handle its designated responsibilities. It is essential to run this command after every hardware replacement to make sure the node is back sharing responsibilities of the cluster.  Health check Most of the problems in the cluster are easily diagnosed by the health check command “ncc health_checks run_all” At the end of every WARN/INFO/ERR/FAIL plug in we see a KB to further troubleshoot the issue. This check is essential to make sure if the cluster he

Good Day to All!I would like to understand how the resources (CPU, Memory) get allocated while creating Database specific compute profiling through ERA. Does the “DB compute profile” allocate the resources directly from AHV cluster or from ERA VM?

vDisk migration allows you to change the container of a vDisk. You can migrate vDisks across storage containers while they are attached to the guest VMs without the need to shutdown or delete VMs (live migration). You can either migrate all vDisks attached to a VM or migrate specific vdisks to another container. In a Nutanix solution, you group vDisks into storage containers and attach vDisks to guest VMs. AOS applies storage policies such as replication factor, encryption, compression, deduplication and erasure coding at the storage container level. If you apply a storage policy to a storage container. AOS enables that policy on all the vdisks of the container. If you want to change the policies of the vDisks, create another container with a different policy and move the vDisk to that container. With live migration of vDisks across containers, you can migrate vdisk across containers even if those vdisks are attached to a live VM. Thus, live migration of vDisks across storage container

You can configure a VM to boot over the network in a Preboot Execution Environment (PXE). booting over the network is called PXE booting and does not require the use of installation media. When starting up, a PXE-enabled VM communicates with a DHCP server to obtain information about the boot file it requires. Configuring PXE boot for an AHV VM involves performing the following steps: Configuring the VM to boot over the network. Configuring the PXE environment.  The procedure for configuring a VM to boot over the network is the same for managed and unmanaged networks. A VM that is configured to use PXE boots over the network on subsequent restarts until the boot order of the VM is changed. To configure a PXE environment for a VM on a managed network on an AHV host, do the following:  Log on to the Prism web console, click the gear icon, and then click Network configuration in the menu. The Network dialog box is displayed. On the Virtual Networks tab, click the pencil icon shown for
