Hello guys,Nutanix is offering the Mine product integrated with Commvault, however, I do not see a guide in Nutanix Portal, though I found the following guide in the Commvault website:https://documentation.commvault.com/fujitsu/v11/essential/144801_configuring_commvault_plug_in_for_nutanix_mine.htmlIt describes the steps to install and configure the Mine Plug-in for Commvault. Still, a step-by-step guide procedure is missing to install and configure the entire product (Mine with Commvault). I wonder if someone can help me with that?>Do I install Commserve manually as a VM? In Mine with Veeam, there is a Foundation Mine with Veeam wizard that orchestrates the installation and configuration.>Do I create the S3 Object Store manually?>If I want to externalise the backups on the S3 store to a tape server for example, what about replicating that storage, is that possible?>Is the NUS Pro license the only license I need for this to work? I also have a few Commvault Backup & Rec
I opened a thread a month ago about Cloud Connect S3 consumption and when checking on it today I found that it was closed to comments.https://next.nutanix.com/nutanix-disaster-recovery-29/aws-cloud-connect-s3-consumption-issue-41499?postid=63137#post63137There was no explanation for this action in the thread or via PM to me. Can someone let me know why this was done?
RDP to guest vm’s running Windows Server 2022 are freezing a few seconds after connecting. Running latest VirtIO drivers 1.1.7. After rebooting the guest, RDP seems to work ok for an hour or so before freezing again. Guest memory utilization 48%, CPU 3-5% so no issue there.
Hi!We are running about 100 vm’s in our cluster - so find out a specific information manually for each vm is pretty hard.I want to get the information which vm’s are stored in a specific storage container with acli on cvm.I know that i could perform acli vm.get <vm-name> and look for the source_nfs_path of the vmdisks but it is way too much effort for 100 vm’s. Another way would be establishing a connection via SSH to /storage-container/.acropolis/vmdisk of of the cvm but i only see the vmdisk-uuids there, not the vm names i need.Is there any possibility, maybe with a for loop on each vm and a grep filter?
For installing a Ubuntu Server Cloud image is it still required to customize it to add the serial port as described in a 2-year old article in this forum for installing Ubuntu Server Cloud. Also do Ubuntu Server 22.04 OVA images work or must use .img? See: Ubuntu 22.04 (Jammy Jellyfish) [20230107]
本記事はAnoop Jawahar氏 および Sandeep Madanala氏が 2021年10月4日に投稿した記事の翻訳版です。原文はこちら。 歴史、背景、動機Nutanixクラウドオペレーティングシステムは、Webスケール、スケールアウトな設計を通じて、高可用性、レジリエンス、障害無害化能力とともに、包括的なストレージとコンピュートの仮想化を提供し、オンプレミスのデータセンターでパブリッククラウドのエクスペリエンスを、提供しています。当社のソフトウェアの基盤となる2つの主な技術は、Nutanixの分散ストレージと、コンピュート管理のためのKubernetesベースのマイクロサービス・プラットフォーム（MSP）です。あらゆるパブリッククラウドサービスで同じようなテクノロジーを利用することができます。例えば、ストレージであればAmazon Web Services（AWS）のElastic Block Store（EBS）やAzureのマネージドディスク、コンテナのオーケストレーションであればAWS Elastic Kubernetes Service（EKS）、Azure Kubernetes Service（AKS）、Google Kubernetes Engine（GKE）などが挙げられます。 今日の分散型データベースやデータサービスは、こうしたクラウドインフラストラクチャーの構造を活用することで、より軽量で先進的なものになります。また、モダンなデータアプリケーションは、あらゆるパブリッククラウドやプライベートクラウドで実行できるように、一定の原則に従う必要があります。アプリケーションをクラウド対応にするには、通常、オープンソースのAPI標準へ準拠したり、標準化されたiSCSIストレージをエンドポイントとしたり、インフラストラクチャ運用管理用のKubernetes（K8s）のようなオープンコンテナオーケストレーションフレームワークが必要です。 Nutanix ObjectsチームがChakrDBとの協業を開始したとき、Nutanixの開発チームは当社のクラウドOS上のストレージサービスを作成していました。Nutanix Objectsは、非構造化データ向けのS3準拠のハイブリッドクラウドストレージで、クラウドの構造を活用できるよう構成されています。クラウ
Hi all, After completing the ECA online course and earning the free exam voucher, I am unable to schedule for the NCP-MCI exam on the NutanixUni-PSI exam dashboard (https://home.psiexams.com/#/dashboard/regular-dashboard). At the bottom area where the schedule link ought to be located, I am instead seeing this block of text: “You can schedule an exam if you have previously contacted a PSI Customer Support representative and paid for an examination, or you believe that your licensing or certification agency has provided PSI with eligibility information for you.” Any help would be appreciated!

Hi,I have two Nutanix clusters on different sites (one on each site) a few miles apart with 10GB low latency networking in place.I have setup a two node failover SQL Server cluster for HA on a single site, but I would like to add DR to the solution.I know Availability groups (and other options) are a good solution for this, but we can’t implement those at present and so I am looking for the ‘correct’ way to replicate the two node HA that we have (With it’s shared storage) across to the second site so that our front-end application will continue to function in the event of a site failure.Any tips or pointers would be very much appreciated!Thanks
Hi,We have two locations and want to install Two-nodes-Cluster in the production location and One-node-cluster in the Disaster Location and to replicate these clusters each other. My question is:Can we connect two-nodes directly with 10 Gbit DAC SFP+ cables each others? So, Is physical switch necessary to install two-nodes-cluster? We want to use Direct Connection (via DAC Cables) for RF2 data replication between two-nodes and 2 x 1/10 Gbit Base-T port will be using for VMs connection and replication VMs to one-node-cluster in the DR site. Is this scenario possible? What about fail-back scenario? (back from DR to Production)Notes:We have 3 x NX1175S G8 Nodes We want to use AHV or ESXiThanks.
As title, Does AOS 6.x support Fault-Tolerance on ESXi 7.x ?If positive, does it support more than 4 FVTM in an ESXi 7 host ? I had read https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-57929CF0-DA9B-407A-BF2E-E7B72708D825.html . Can I change parameters to support more than 4 FTVMs in an ESXi host?
