VM Throttling

Is it possible to implement throttling at a per VM level? The thoughts/scenario behind the question: We have had on a couple occasions where we found a VM (different in each occasion) that was running away with storage controller IOPs. Of course the goal is to get the actual issue resolved for the offending VM, but we would like to be able to implement throttling to be able to assure other VMs in that cluster don't suffer when this does occur. Disk I/O has been the scenario so far, but could also see the need to throttle CPU, memory, and/or NIC throughput at some point.

Migrating from Hyper-V to AHV

Does anyone know of any official documentation on the best way to perform a migration from Hyper-V 2016 on Nutanix to a new AHV cluster (not an in place migration)? Or any good guides on doing this? It is going from Hyper-V 2016 to AHV but 2012 would be helpful. I have found a few articles but they are either quite old or not very well written.

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)

Space reclaimation for LINUX servers - RHEL 6.7 * VMWare 6.5

Hi All, Hope you are doing well. I have question regarding the storage usage and space reclaimation in VMWare 6.5 with Nutanix clusters. This question is more into VMware instead of Nutanix, thought of checking here. Just to give a overview we have Nutanix nodes and we have got VMWare 6.x installed on the nodes, a single storage pool and multiple containers. I got a RHEL VM migrated from the old environment and it got 4 disks (10GB, 20 GB, 500GB & 5 GB), all the 4 disks are in the same DS and thin provisioned. No deduplication & compression enabled on those. Now when I access the VMware web console and look for the vmdk files by browsing the files in the DS, I can see a different capacity from the actual usage compared at the server level. When I see the same VM via PRISM and I cannot see the 4 disks assigned to it. It shows only 1 disk with some 160 MB used out of 20 GB and none other than that. Could you please help me to understand why its not showing the disks in the P

XenServer to Nutanix AHV VM Migration ERROR [Boot Device not found]

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.

CVM Resources Allocation

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?[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/2333i06E549D1B99C0D7A.png[/img]

Nested Shares on AFS

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

IBM Lotus Domino

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.

VGLB and AOS 5.6

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

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

Proper licensing of Microsoft VMs running on PRISM/Acropolis Pro

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

Server 2016, DirectAccess Role and AHV

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?

Storage Efficiency, Data Reduction, and Performance with Compression

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

ESXi 6.5u1 Upgrade on AOS 5.1.1.3

I have recently upgraded my vCenter from 6.0 -> 6.5u1, and I'm not looking to upgrade my ESXi 6.0u3 installs to 6.5u1. My first attempt was to use one-click hypervisor upgrade, and I was able to uploading the ISO and MD5 checksum, but the pre-upgrade check errors out pretty quickly with a fairly generic error message saying "unable to determine version of bundle." Did a few re-download and re-upload attempts to verify my file integrity but the error persisted. I then tried to do the upgrade old-school style using VUM which is conveniently baked into my VCSA as of 6.5, and I got another generic error message inside of update manager, "The upgrade contains the following set of conflicting VIBs:" with nothing but blank space following the colon. Typically I would have expected to see an individual VIB called out in list form, but there is just nothing there. I am fully patched to current using Nutanix LCM, so I suspect it is probably one of the LSI HBA updates that LCM has slipped in
