Nutanix Cloud Infrastructure

Hi,I am trying to move a Windows Server 2012 R2 VM from Xenserver to AHV. With reference to this article: AHV | Migrating a Windows VM from XenServer to AHV everything is working great except when I am at the last step. When I turn on the VM in AHV, I am getting a boot device not found error and windows will not boot up.Windows will start with a windows icon throws the error and restarts, then goes into disk repair, reboots and same error and goes into the troubleshooting menu and when I am restart the VM in AHV it again and always goes into the boot disk inaccessible error.I made sure all the Xen components are already uninstalled from the vm and Nutanix VirtIO drivers are also installed. Tried with loading the image as scsi and IDE, but still going into the same error. Also tried booting up in safe mode, tried disk repair, etc. but no luck.Please help if someone has a solution.PS: I am migrating Windows Server 2012 R2 from XenServer to Nutanix AHV.

What options are available within nutanix to speed up replication to a remote site? The best i am able to get on a single stream is about 20MBps (160mbps) with an aggregate speed of about 60MBps (480mbps) spread out over several streams. However, we have a 10gbps link between sites, so i expected to get better throughput.

Hi All, I've just published an article on my blog regarding what I consider the top 5 best practies or tips for successful SQL Server virtualization projects. Thought you might like to check it out: http://longwhiteclouds.com/2017/02/01/best-practices-for-running-sql-server-virtualized/ Kind regards, Michael

Hi everyone, I´m trying to export the VMs from AHV in vmdk and qcow2 formats directly from a CVM. Sometimes I get the errors bellow: qemu-img: NFS Error: NFS: Write failed with NFS3ERR_JUKEBOX(-11) qemu-img: error while writing sector 44426880: Resource temporarily unavailable In other situations Putty just close in the middle of the copy. After several retries, I finally made backup of two big VMs (around 50 gb). The commands that I am using are: qemu-img convert -O vmdk nfs://127.0.0.1/TKWORKSTATION/.acropolis/vmdisk/d9759595-6dee-4138-bcc0-bad7bf8e1075 nfs://127.0.0.1/Backup_VM/TAIPEI.vmdk qemu-img convert -c nfs://127.0.0.1/TKWORKSTATION/.acropolis/vmdisk/d9759595-6dee-4138-bcc0-bad7bf8e1075 -O qcow2 nfs://127.0.0.1/Backup_VM/TAIPEI.qcow2 Nutanix Community lastest version. Thanks in advance!

Hi, Our customer would like to utilize the snapshot feature on Nutanix AHV as backup solution. They would like to know if they could create Application Consistent snapshot. I did some research. 1. In the Web Console Guide which mentioned about Application-Consistent Snapshots "This option is available for ESXi only; it is not supported for Hyper-V or AHV. However, athird-party product could be used to invoke VSS when the hypervisor is Hyper-V or AHV." 2. QEMU should have guest agent and which the VirtIO Driver should have included. So, my question is. Can Nutanix AHV support Application Consistent snapshot. Thabnks

Hey Everyone. So, I am relatively new to the whole Nutanix game. Im curious what everyone is suggestion is for CVM allocation. We had nutanix do our original provisioning, but the provisions the installer set it up with seem a bit excessive. 10 Cores and 32gb ram per CVM, Any thoughts?

Hi, we have the need for nested shares on our fileserver. While this was easy on NetApp Filer it seems impossible with Nutanix AFS, or I am missing something. We are currently on latest GA release AFS 2.0.2. with AOS 5.0.2 on ESXi 6.0U2. Is this on the roadmap or even possible with AFS 2.1? Replacing Fileservers (Windows or NetApp, doesnt matter) could only be done with full feature set. best regards Steffen

I am suffering with exausthives crashing in my Domino server and IBM support said that the possible problem is related to disks. I did an analysis in Prism and there are really trace of problems. The storage bandwith for this VM is much higher than all others. Is there anyone running Lotus Domino sever on Nutanix Cluster? I would like to hear your feedback and feeling about it. I am using Nutanix with vSphere 5.5.

As the most of you probably know, with AOS 5.6, has been introduced the Volume Group with Load Balancing function, well known as VGLB As i know the 5.6 version is in short term support. Now i'm deploying a two Oracle 12c RAC clusters on 2 8000 6-nodes AOS-AHV clusters with AOS 5.5.3.1. It involves using volume group with multiple vdisk, network related configuration, Linux related tuning and so on... Of course, with 5.5.3.1 (so far the latest GA version in long term support), i've not the VGLS choice, every volume group's I/O is managed by a single CVM. By the other side, with AOS 5.6, i could distribute this load on every single CVM and every single node storage on the cluster. Of couse this heavily impact on the resiliency, the performance and the resources distribution. The questions are two and i need some suggestions. 1) could be better to upgrade to 5.6 even if it is in short term support? 2) is it possible to update "on the fly" the volumes's configuration with "vg.upd

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): The traffic entering and leaving a Nutanix cluster can be broadly classified into the following types: Backplane trafficBackplane 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.) Management trafficManagement 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 backplane network, and th

Hi, I'm struggling with backups while using KVM. We've been using snapshots for our standard backup process and these work just fine within the cluster. I can recover a VM either as a new clone to retrieve lost files or to directly replace the original in case of a major crash. My next problem is exporting those snapshots to another cluster (since DR isn't available for KVM yet) or to a non-Nutanix archival server. That appears not to be possible. Everything I've been suggested so far involves backing up the VM internally or copying the iSCSI device with dd which would involve us having two completely separate backup processes running in parallel. Not fun. Is there a way to export the Nutanix drives to another server? Logically they must exist somewhere so should be copyable.

Does anyone know if/how I can get a count of all vDisks in my cluster, including vDisks associated with snapshots? We want to increase our data retention and it appears the limitation on snapshots is the number of vDisks so I need to figure out how many we have with our current number of VMs and snapshots. Running AOS 5.6, NCC 3.5.2, Hyper-V 2012r2. Any help appreciated, please let me know if there's more info I can provide. Thanks! David

Hello, When I try to do a consistent snapshot I get this: Warning : Vss snapshot failed for the VM(s) xxx, protected by xxx because Quiescing guest VM(s) failed or timed out. Impact : Crash consistent snapshot is taken instead of application consistent snapshot. Cause : Guest is not able to quiesce VM due to internal error. The servers has the NGT installed, are alone in the consistency group. Before I open a case, I'd like to have your hindsight. Thanks.

With this new product comes a change to how Veeam licenses their products. All new products released this year will be per VM only and socket licensing is gone. As I understand it, customers who already have socket licenses will be able to renew their product, but what if they jump to AHV? I'm pretty sure Veeam counts this as a new contract as you purchase Veeam with your Hypervisor type. This means you too may likely move to a per VM model of licensing. But, isn't this a good thing? Doesn't it reduce my costs? That is up for debate per environment. I just wrote my Veeam account rep about this licensing change and gave him the reasons why I don't want a per VM licensing model as a Veeam customer. Here's a copy of that message. Think about this for a moment: Veeam Rep, I want you to not charge me per VM and offer me socket licensing like we had approved. It’s clearly a model made by executives who are out of touch with how businesses operate and only thinking about h

Good evening. We are evaluating some nutanix offerings from a local partner. However I have some Microsoft related question and the partner is taking too long to respond. 1- Is there a version of Nutanix Acropolis/PRISM (4 node)that allows me to run unlimited Windows VMs without me needing to purchase a MS Windows DataCenter Core License from Microsoft? 2- Is there a PRISM/Acropolis Pro version that comes with a built in Windows Datacenter valid license? Or 3-Do I need (as usual) to buy my Datacenter Core licenses to properly license my new Windows VMs? Thanks

Can I use Hycu without Calm and Prism Central? if I can, how to I use it? Our hypervisor is ESXI. Could you recommend some documents. Thanks.

I have a BOM based in cluster 1465 G6 and the end customer wants the estimate IOPS or performance that the solution can be reach. ¿Where I can get this information? Regards.

I'm monitoring server from NUTANIX found memory full 100% anytime , How can I fix for this problem?

I am currently running VMware but will be soon switching to AHV. Will be purchasing a APC UPS with parchute software. Does anyone know if this is compatible for AHV? Does anyone out there with a UPS running AHV care to comment how they are managing the graceful shutdown of their Nodes and VMs in the event of power loss?

DPM of Microsoft can integrated with Nutanix Acropolis Hypervisor?

My issue is related to installing the Direct Access role on a AHV VM running server 2016. Here is my environment. AOS: 5.6 Hypervisor: Nutanix 20170830.115 Windows OS: Server 2016 VirtIO Drivers 1.1.2 Server Imaged with SCCM I've deployed many Direct Access servers in the past and I am seeing very unique issues with trying to configure it on AHV for the first time. 1.) After configuring the role, the Tunnel adapter 6TO4 is NOT created 2.)After configuring the role, the Tunnel adapter IPHTTPSInterface is NOT created 3.)After configuring the role, the server fails to retrieve gpudpates 4.) Upon rebooting the server, the Distributed Transaction Coordinator service fails to start. However, if I deploy the EXACT same server image on a VMware VM, it works perfectly. Is there a known issue when deploying the DirectAccess role on a AHV(KVM) VM?

Hi, Im currently looking into a 3-node Cluster layout with NX-1155 hosts and PRO license as Remote Site for DR. I would like to go for 3 nodes instead of a single node configuration because it can withstand block/node failures. But Im trying to keep it low on the price scale. The one thing that keeps bothering me is that I want to be able to start a few user vms on the Remote Site. I know its possible but 64GB of RAM per host isnt much especially when the CVM blocks at least 24. It has to compete against a 3node CE installation which im not in favour because i would like to have support/production grade software. But I could get hosts that supports more RAM and start more VMs if I need to. What do you think?

Hello, like other post i know if exist an UPS brand to graceful shutdown Nutanix clusters in Vmware enviroment. I've read that about APC, is ti working? https://next.nutanix.com/blog-40/apc-powerchute-network-shutdown-is-certified-nutanix-ready-core-management-operations-19890 Thanks in advance

Can any one high light or point me the core technical differences between AFS and native file services solution??

Nutanix Tech Marketing Engineer Andy Daniel wrote up a short paragraph recently as an overview to the Storage efficiency features including compression. Share what you are doing for your different workloads in your environments (Nutanix or otherwise). -- To optimize storage capacity and accelerate application performance, the Acropolis Distributed Storage Fabric uses data efficiency techniques such as deduplication, compression, and erasure coding. They are intelligent & adaptive, and in most cases, require little or no fine-tuning. In fact, two levels of post-process compression are enabled in conjunction with cold data classification by default on new shipping clusters. Because they’re entirely software driven, it also means existing customers can take advantage of new capabilities and enhancements by upgrading AOS. DSF provides both inline and post-process compression to maximize capacity. Many times, customers incorrectly associate compression with reduced performance, but this
