Nutanix Cloud Infrastructure

Our CVMs are configured with 32GB of dynamic memory. Start, minimum and max are all set to 32GB. I'm curious to know why Dynamic Memory is enabled on these VMs? Since the CVM's OS isn't fully Hyper-V integrated, we don't see memory demand from the hypervisor (this is the only benefit I see from leaving dynamic memory enabled on a VM with all values set the same). As an explicit downside, since we're using Dynamic Memory on these VMs, we lose the vNUMA featureset (not that a 32GB VM is likely to benefit from it). Thanks!

Hello guys, i am new for nutanix. i have problem with start action hyper-v. I installed on nutanix use Hyper-V, NOS 3.6.1.1. when i created VM and configuration on automatic start action i choosed option "Always start this virtual machine automatically". but that option not function. Can you help me? Thanks.

Nutanix AOS v4.7.5.2 3 x Dell XC430-4's ESXi v6.0 Express Patch 7a vCenter v6.0 Update 3b I have created a VM exactly how I want it. This VM uses Thick Provision, Eager Zeroed. I power it off and start the cloning process. When the cloning process is finished, I check the new VM's disk format and it is always Thin Provision. I have tried cloning with the option Disk Format = Same Format As Source, and Disk Format = Thick Provision, Eager Zeroed. No matter what I choose, the new VM always ends up with a Thin Provision disk. I do have VMs on the system that are Thick Provision, Eager Zeroed. Also, I tried to INFLATE the VMDK file for the newly cloned VM, and while the system seemed to go through the motions, the VMDK file remained the original thin provison size. Any help is appreciated. - Dave dclausse@scgov.net

Is there an option to Pin to SSD in AOS v4.7 with vSphere hypervisor?

Hi, I'm having this issue, wich I seem to be the only one in the world to have.I'm new to the Nutanix world so I apologize in advance for any dumb question I may ask.:-) We've just deployed a new Nutanix block with 3 nodes running the latest version of everything and using VMware ESXi 5.5 U3b for hypervisor. It is deployed in our vCenter Server as a separate cluster (there are two other cluster running older H/W not Nutanix but all the hosts are on the same 5.5 version) The problem is with vDP. If the appliance is running in the NTNX cluster then I can't connect to it with the vSphere web client. There's no error message whatsoever, the little clock keeps on ticking. If the appliance is running on one of the older H/W, I can connect to it (like I always did for the past 5 years) But, if I go an modify one of the backup jobs to add a VM running on NTNX, when I try to save the job, the client hangs indefinitely and the job is never saved. I've been searching blogs, knowledge base,

Is there any chance of being able to use built in backup to work with Backblaze B2? Is there any feature request to have this done? It is much cheaper than Amazon or Azure.

Hi, Running 3 node Lenovo HX1310 with AHV 5.01. I will be opening a ticket with Nutanix support. This more of an FYI.... First saw this issue with and SBS 2011 Standard (aka Windows 2008 R2 x64). After migrating from Hyper-V 2012 R2. I was/am having issues where the system would freeze. I first thought it was ShadowProtect backups causing, but then it started happening late at night. I think its the WBengine Service (aka Block Level Backup). I setup a fresh test Windows 2008 R2 with 2 volumes, C: and E:. When I ran chkdsk on the c: drive it gets to the end, stage 3 of 3, and then the VM powers off. I have to start it manually. So I tried it on the E: that has no data is freshly formatted. I run chkdsk, and the VM powers off. Update:Just tried the same chkdsk /f on a Windows 2012R2 server and the same symptoms appear. Thanks in Advance, G

With regards to SQL licencing - how does Nutanix handle the cost per core issue? pertaining to the cost per cpu how does Nutanix solve sql licencing (per core) issue

Hello Everyone! I am using AHV and would like to create a duplicate of my production environment alongside the actual production environment. The point is that we have some highly specialised network software that needs to be tested as though in the actual environment before we actually deploy it there. This software is frequently updated and occasionally an update creates havoc, requiring lots of downtime and restoration of significant portions of the network. So what i am looking for is to have a protected space in AHV that thinks and behaves identically to our production environment (but with no actual interaction with the real network or the internet ... just via AHV consoles.) Thank you in advance for any help you can offer!

Hello, I am receiving the following alert: "Old generation AWS instance is configured for remote site AWS. Follow KB 3861 to change the instance type to m3.2xlarge and cloud CVM configuration for better RPO/RTO." The remote site was configured only about a week ago and it spun up an instance size of m2.2xlarge. I cannot find any reference to the KB article 3861, or anything about changing the instance size. Does anyone have any ideas? Many thanks, Daniel

Hi, Can someone advise if possible to present iSCSI block services from DFS to Hyper-V host running on Nutanix Cluster. We have AOS 5 and we running Hyper-V 2012 R2 on our Nutanix Nodes. Why? This is to address problems with backup of VMs on SMB3. Possible alternative: Present iSCSI volumes from the underlying DFS to the Hyper-V nodes and migrate from SMB3 to iSCSI for VM. Then we should be able to do full VM back ups?? Would love to hear opinions / experience / feeback on the above idea. Thanks.

Hello, Could anyone offer ideas around how to manage the log truncation for applications like Exchange/SQL when moving to CloudConnect from a product that used to perform that automatically? This seems like a pretty important aspect which I can't seem to find any information on. Many thanks, Daniel

I've a couple of vms building a windows failover cluster. Shared storage is provided by a NDFS volume group attached to vms using iscsi. It's possible to create a vss enabled snapshot of this cluster?

I'm looking into backing up our Nutanix Acropolis cluster to either Azure or AWS. What I'm curious about are the actual costs once you factor in not just their basic storage rate, but Puts and data writes and everything that happens during a backup and restore (rare as those would be). We have around 5 TB total with all our VMs, with the daily snapshots averaging around 40GB in changed data. We would want to retain maybe a month's worth of backups with dailies and weeklies. Is this enough data to do a decent estimate, or is it one of those 'Try and see' scenarios? I'd be interested in anybody else that's utilizaing it as a remote backup site and what kinds of costs they're seeing. Thanks! Clint

What are limitations of different bus type for hard disk i.e. SCSI, PCI, IDE? will there be any performance impact?

Can know impact of SSD failure if each node has 2 SSDs in slot0 & slot1: 1. Slot0 SSD failure 2. Slot1 SSD failure 3. Both SSDs failure (Know this will be CVM failure)

If I add one additional node with 512 GB ram to my existing cluster which consisit of 3 nodes of 256 GB each, how N+1 will be calculated?

Need to know when we say RF2 how many copies of data A will be created? one copy i.e. one primary original data & secondary one. Or one primary orignal data & 2 secondary copies.

Hi all! Is anyone out there running Cloudera in a Nutanix environment? Not just Hadoop, but specifically the Enterprise Cloudera Hadoop implementation. We're in the process of migrating our Production Cloudera cluster to Nutanix VMs and having a host of issues related to disk latency. I'm aware of the Nutanix Hadoop reference documents, but our configuration doesn't quite fit because it started on physical devices, and the existing production configuration would be challenging to change at this point. We're not running YARN yet, still on MapReduce V1, for example, though we're in the process of moving that direction in our dev environment. We have a storage container devoted to our HDFS directories, with virtual disks carved out of it in VMWare, but we're seeing vdisk latencies *averaging* 300ms with frequent spikes to several seconds. Our I/O is very write heavy; Nutanix advised us to disable EC-X, so we did, but no help. We're running RF2 on that container, no deduplication,

Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor. Normally we using passwordless login to the ESXi host using SSH Keys. So we copy our public key as usual to /etc/ssh/keys-%u/authorized_keys, but after a reboot of the ESXi Host our keys are removed.So I modified the sshd_config on the ESXi host to use multiple authorized_keys- AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys+ AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys /etc/ssh/keys-%u/authorized_keys2But even with this config, the authorized_keys2 is also deleted.Can anyone assist me to solve this issue in case of our internal security guidline to use passwordless login.Best regardsMarkus

How do Persistent Reservations work with Hyper-V on Nutanix? I'm asking because with our other "Hyper-V with SMB Storage" clusters, you are not able to use Hyper-V manager on HOST1 to modify VHDs that belong to a VM running on HOST2, 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 (not Failover Cluster Manager). Edit Disk to resize a VHD of VM1. Resize successful (This fails in our non-Nutanix clusters) Using HOST2, check the properties of VM1’s VHD and you will notice that the file size has changed Using HOST1 (where the VM is running), check the properties of the VHD and you will notice that the file size HAS NOT changed Reboot VM1, server will not boot – VHD is now corrupt[/list]Is this a known issue/bug? I understand

Hi all, I just started to write a deployment script for VMs on AHV cloning from a template. Using Sysprep lots of OS Customization is already possible. However, I would like to know if there is a possibility to run a (powershell) script in a Windows 2012 R2 VM on AHV while it has not configured any NIC yet. I know I can easily login via console and start every script I want, but I would like to run it fully automated within my deployment script from my client (for several VMs). Any ideas?

Is anyone utilizing Unitrends as a backup solution? I was looking at their appliance offering with cloud offloading since they do not charge for recovery. I also have a 3 node Nutanix block running VMWare 6, but still have a few physical servers that will remain physical for a little while longer. Thanks for any feedback.

As a pre-step to a planned failover, I want to take a snapshot of each of my Metro PD's (4 total). Together, they are over 5 TB in used storage. Since they're all in the same Storage Pool I plan on doing one at a time so as to not compound the i/o load - does this make sense? Also, can anyone provide a *rough* estimate of how long a PD snapshot should take to complete? Thanks!
