Deployment Success

We are thinking of adding two compute only nodes to our cluster for Oracle.  What are the hardware requirements for running CO nodes?  Does the cluster the CO’s are joined to have to be all flash or do you have to “pin” the VM’s running on the CO to All Flash in the HC storage.   We currently have 4 HC nodes running a mix of SSD and HDD. 

Security and encryption are backbone of an IT infrastructure. Many organisation have made it a compliance to encrypt data and keep the data on-prem. Nutanix also provides industry standard security features. One of them being :DATA-AT-REST ENCRYPTION Nutanix provides an option to secure data while it is at rest using either self-encrypted drives or software-only encryption and key-based access management (cluster's native or external KMS for software-only encryption). Want to more about D-A-R-E and it’s features? Go through the following guide D-A-R-E guide    During various compliance auditing and administrator task, we need to verify if D-A-R-E is enabled and successfully working or we need to configure D-A-R-E How can we safely accomplish that? We have different methods using which you can verify that D-A-R-E is enabled or not . You can use these methods to automate the process of verification or configuration. Go through the following KB to know about the various methods with comm

Hi, I am having a Hyper-V cluster managed by a SCVMM with Kerberos enabled. I already did: Join the cluster and hosts to domain Create the MSFC and join to domain Add hosts and Nutanix container share to SCVMM Enable Kerberos and configure Delegation But, from each host, I currently cannot: Access to Nutanix container via SMB path (\\VIP\container). When I type the SMB path into file explorer, it requires me to login. I tried to use the AD account used to enable Kerberos on Prism as well as AD admin account but could not make it Create the VM (I could create the VM by using SCVMM instead). “Failed to create the virtual hard disk” error window appears every time  I try to create Is this the normal behavior of the whole system? As I am quite new to Hyper-V, I am getting lost in finding the solution to solve it

Confused regarding crash-consistent snapshot and application-consistent snapshot? Crash-Consistent SnapshotVM snapshots are by default crash-consistent, which means that the vDisks captured are consistent with a single point in time. The snapshot represents the on-disk data as if the VM crashed or the power cord was pulled from the server—it doesn’t include anything that was in memory when the snapshot was taken. Today, most applications can recover well from crash-consistent snapshots. Application-Consistent SnapshotApplication-consistent snapshots capture the same data as crash-consistent snapshots, with the addition of all data in memory and all transactions in process. Because of their extra content, application-consistent snapshots are the most involved and take the longest to perform.While most organizations find crash-consistent snapshots to be sufficient, Nutanix also supports application-consistent snapshots. The Nutanix application-consistent snapshot uses Nutanix Volume Shad

Is it necessary to have 2 vlans when deploying nutanix or can I deploy nutanix with one vlan?

Dear Sir/ Madam, I am working on a further Nutanix project and I have installed 8 x NX8155 servers. Each server has 6 x 10g TwinX cables and 2 x CAT6 copper connections. I am again trying to find any suitable cable manager due to the amount of physical cabling for each device. Can someone please advise if there are any cable managers that Nutanix is aware of or via a third party as I am struggling to locate any. Thanks in advance. Simon.

Hi, I am new here and this is my firts experience with Nutanix. I need to deploy 3 nodes, and I’ m going to use the native Hypervisor from Nutanix (AHV). I saw a video explainning that,  to do it, it’s necessary to download and use the Foundation Tools to configure the cluster and than, gathering access to PRISM. Unfortunally, I can’t download Foundation, due to the Nutanix blocks were registered by our customer (message: ...The email XXXXXXX is not authorized for the account associated with the serial number YYYYYYY) and we don’t know who did it. We are trying to identify who registered the blocks but, meanwhile, Is there another way to deploy it without the Foundation tool, or is there a way to unregister the blocks and register again but to different user account?   Thanks in advance,

Hello all,   Hope you’re all doing great. Kindly if you can guide me where to start with Nutanix as I don’t know anything and willing to know everything related .. so I am a VMware guy who is willing to understand the NU platform and I hope I am writing the right post in the right place      Thanks in Advance, Cheers.

I completed an AOS upgrade from 5.5.2.2 to 5.10.8 on two different clusters.  On one cluster I have the health page showing a warning symbol (no data) and the message: “An error has occurred. Show me why” When I role over “Show me why” I see the message “java.lang.NullPointerException”.  I have a ticket open with Nutanix but haven’t received any solutions that have worked yet. Appreciate help if someone knows how to resolve.

When i try to connect to IPMI by clicking on the link in Prism Central i get an error stating the site can not be reached because it timed out.  It seems to be related to the firewall maybe.  Any information where to start? thank you

Hi, We have a NX-3060-G4 with 3 VMware hosts on that is currently connected to our Cisco core switch cluster using 10GB twinax cables. A long story short, I need to remove these and connect the NTX to a single 1GB Cisco switch (WS-C3850-12S-S). My question is: can I connect a 1GB SFP link between the NTX and new core switch using the 10GB NTX ethernet port? If so, will the NTX detect that the cable connected can only run at 1GB?   Thanks in advance.

 In some scenarios, we might have a need to find the disks associated with a virtual machine hosted on a Nutanix AHV Cluster. Nutanix offers a distributed storage fabric, which forms a large storage pool across “N” number of nodes. we then create containers for different types of workloads or we can easily use a single container as well.Virtual Machines are created via Prism Management and all vDisks associated with the VMs are hosted on the distributed storage pool. On a Nutanix AOS Cluster, Acropolis service runs across the cluster to manage virtual machine operations and configurations. As both Data & MetaData is distributed across the cluster, we can use the “Acropolis” service on almost any CVM to retrieve virtual machine information running on any node.In order to interact with the Acropolis service, Nutanix offers “acli”. a powerful set of commands for virtual machine operations across your Nutanix cluster.acli offers tab-completion once inside the acli shell or we can execu

Impact : If hostd service is not running, AOS upgrade will fail. Cause : VMware hostd service may not be running. Resolution : Check hostd status and restart it manually.

Hi All,   Is it possible for a Witness VM to monitor multiple two nodes clusters?   I can’t find any answer on this question.   Thanks in advance.

Nutanix AOS supports multiple hypervisors and supports a variety of hardware components. Nutanix qualifies hardware components to ensure optimal performance and minimal disruption.  Nutanix AOS with ESXi supports Intel’s 10Gb (ixgbe) Ethernet Network Adapters. It is important to ensure that all network related components are working optimally to ensure reliable cluster operations.  If you are running Nutanix AOS with ESXi 5.5 or 6.x and have the following Intel Network Cards installed in your host systems: Intel Ethernet Controllers 82599 and x540 You might receive an NCC alert, pointing to an upgrade required for ixgbe nics or an older firmware detected. This is to ensure optimal networking performance amongst the hosts and to avoid any errors due to NIC driver issues. You can upgrade the firmware for the above Intel NICs (ixgbe) with the following Nutanix KB: Updating the ixgbe Driver Version to the 4.5.1 Release The above KB outlines all the pre and post steps required for a smooth

  I have AHV cluster at both DC & DR, which has number of VMs being protected with Protection Domain feature. These VMs are being replicated from DC to DR in scheduled manner. Now as a part of DR drill, I need to run these production VMs from DR for period of time and then again make it functional from DC once drill is over. I am concerned over how the delta changes made during drill with VMs at DR will be again replicated back to DC as Protection Domain replication is uni directional (DC to DR) ? Any recommendations ?

Hello, I'm trying to create a File Server. I did this in Prism Element cluster. I have a problem when I had to select the Client Network PortGroup All my dvportgroup are not visible. I can only see the dvportgroup attached to a dvswitch with uplinks assigned. In my vCenter we have a dvswitch with no uplinks assigned. This dvswitch is used by my network sdn solution which transport the client network. Do you see a solution ? thanks
