Data Protection Concepts

Regardless of the type of data you generate on your VMs, the data has to be backed up and safe. how do you make sure of that? a first step is to understand our basic approaches and how do we guarantee data resiliency.  The importance of data protection increases as the amount of data generated by your VMs continues to grow at unprecedented rates by expanding your storage pool, adding nodes to your cluster and deploying new Virtual Machines. To ensure that the data is safe, we have different approaches, here is a brief explanation for each:  Protection Domain (two types) Protection domain - Asynchronous DR: is a defined group of entities that consists of VMs and Volume groups that are backed up locally on the cluster and can also be replicated on a remote site.  Protection domain - Metro Availability: is a pre-specified and an active storage container in the local cluster linked to an inactive container with the same name on a remote site in which synchronous data replication occurs whe

Different usages for Phoenix

Let’s say that you need to use Phoenix on a node, how do you know which ISO is best for you? the minimal or a bundle of Phoenix & AOS? How do you create the bundle?   The short answer for both questions is, it depends. What is Phoenix? Phoenix is an ISO-based installer that you can use to perform installation tasks on bare-metal hardware one node at a time. Tasks that performed by Phoenix:  Configuring Hypervisor settings, virtual switches and more (no need for AOS in this case) Installing the Controller VM which runs the AOS. Installing the Hypervisor on a new or replacement node.  Repairing the CVM.  If you don’t have access to the CVM and you want to check the data drives’ health, you will be able to see the drives from the Phoenix shell. How do you obtain the correct Phoenix?  Looking at the scenarios above, we can see that for each case you might need a different approach and ISO, but all scenarios require the minimal Phoenix ISO.  You can download the minimal Phoenix ISO from

Network Segmentation - Backplane VLAN with Gateway?

I'm will be configuring Network Segmentation on my Nutanix Cluster as per these instructions. https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-network-segment-on-existing-cluster-wc-t.html The VLAN that I put my backplane traffic on, does it matter or not if I have a Gateway for that VLAN? I would use 172.16.10.0 as the Subnet IP and 255.255.255.0 as the Netmask. I am planning on having a Gateway of 172.16.10.1 on the firewall. Currently, the default configuration without network segmentation, the management and backplane traffic on eth0 has a gateway so as far as I can tell, everything should still work if I have a gateway for backplane traffic. Could someone please confirm that it doesn’t matter if I have a gateway on the backplane VLAN or not?

Compute only node requirements

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.

[Hyper-V] Cannot access Nutanix container by using SMB

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

Crash-Consistent and Application-Consistent Snapshots

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

Cable Managers for Racked & Stacked installed Nutanix servers

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.

Is it possible to deploy Nutanix nodes without Foundations Tools?

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,

NX-3060-G4 - Cable to Core Switch

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.
