What is SSD to HDD ratio followed for nutanix?
Hello- I had a question on remote site best practices. When we create a remote site for PD replication do you think we should create a new container at the remote site for the replicated vms to reside in or just use our existing container that is running that active vms at the remote site? In the second scenario the active vms at the remote site would be on the same container as the snapshots replicating from the PD active site. Just wonder what other people are doing? Thanks, Erik
Hi, Is it possible to assign additional IP to nutanix cluster? Scenario is as follows: 1. Having network class A with 10.x.x.x which is used for CVM, hypervisor communication during configuration. 2. Cluster virtual IP is also from 10.x.x.x range. 3. Added additional IP range of 172.x.x.x to CVM, Hypervisor. 4. Is it possible to add additional IP range IP of range 172.x.x.x to cluster virtual IP? Thanks
Hi, What are requirements of creating Protection Domain with replication at DR / secondary site? Thanks in advance
Hi, How to automate failover in unplanned event using Prism? Thanks in advance
The Nutanix MCS Plug-in seems not to workwith latest VDA release of XenDesktop 7.11. Can you confirm this incompatability? Is there a newer Version of the Plug-in that works with XenDesktop 7.11?
Trying to setup a Nutanix cluster (non prod) to automatically email me the NCC results. Have setup the SMTP and alert email configuration sections in Prism Element. Verified from a CVM that emails are being sent okay. Next, on a CVM, I ran ncc --set_email_frequency=4 and saw that it took successfully. Finally, running ncc --show_email_config but gettting result Value for the flag --show_email_config has not been set. Obviously I am missing something?
The pasword for nutanix user was reset on the prism central system and now I am unable to login even though I am sure the password is correct. It seems it may have become unknown due to the console setting for special characters. In this case how do we recover login access to the node. I didnt set another sudo or other user for this system either.
A rather simple question :) Once the NFS Datastore has been presented to the nodes, each node shows the NFS Datastore and the Local disk as available storage. My question is, how do others deal with this scenario? What is to stop an admin from storing data to the local data store as opposed to the NFS data store which is where you want them to store their VM's? Curious how others have dealt with this. Thanks, Sky
Hello - Trying to upgrade via one-click upgrade in Prism from 4.0.2.2 to 4.0.3. Even though I have "Enable Automatic Download" enabled it does not show 4.0.3 as "available compatible version." However, I have another identical cluster which shows 4.0.3 as available. Anything I am missing to make sure Prism auto downloads the latest NOS from Nutanix? Thanks.
Hello's I have an existing VMware install using a storage array. I have a three node Nutanix cluster that i'll be migrating to. I've read through some of the solutions offered and i have an additional question. When i migrate my VM's using vmotion from the legacy platform, do i have to make a decision to which host on the Nutanix side the VM will reside and if so, do i have to think about balancing out my VM's across the three hosts? Thanks all for your time, Sky.
I'm running NOS 4.7.1 with vSphere 6.0 and loving the seemless vm migration to the remote site using Metro (for a planned outage). Is there a way to perform a failback just as seemlessly - no downtime? After reading through Mike McGhee's v2.0 Best Practices document I wasn't able to find if this is possible or not.
While trying to add a new node to my cluster where I need to re-image before adding to the cluster, the iso_whitelist.json in the foundations downloads page appears to be broke, just redirect back to the support portal. appologies if this is the wrong place to rais the issue Regards, Stephen
Hi, we have installed a 4 node Nutanix cluster. In the installation process you have to select the cluster redundancy factor, RF2 or RF3. We tried to select RF3 but the system says that you need at least 5 nodes. So we were forced to create the cluster with RF2. In the future we plan to extend the cluster with additional nodes, may be only storage nodes. Will it be possible to upgrade from RF2 to RF3 without having to delete the existing cluster and create a new one? Stefano
Hi Folks, I`m installing a new also my first AHV(latest version installer-el6.nutanix.20160601.20,with latest AOS4.7.1). I`m new to KVM,as well as AHV. So some problems met, tough time these days. Any help would be highly appreciated, thanks in advance. 4) centos 4.7 guest vm also the guide 《AMF_Guide-AOS_v4_7》 says only support CentOS 6.4, 6.5, 6.6, 7.0, 7.1, 7.2 Is there a support matrix for all the vm guest type ? [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1561iBAB9B8FBC3F8C6C2.png[/img] 7) kvm vm mgmt via Prism there`s too little function for manaing ahv hypervisor and guest vm via prism(it seems only basic vm life-cycle mgmt). Can I add usb device, make an ovf template like vmware vcenter ? I`m not such familiar with virsh, ovs cli tool
Hey all! Just got my 3 node monster Nutanix box up and running and LOVE it! Quick theoretical question though: I blew through my budget on this box, and would LOVE to have a DR setup somewhere else in the building (to combat fire, flood, earthquake, etc.) Could I take some spare hardware lying around, and as long as it meets the specs needed, install the CE version, and make that the DR for my existing paid for version of Nutanix? I've gotten mixed answers from various people is why I ask. Thanks in advance!
I am a bit confused. On the Nutanix support portal, in the Downloads section for Phoenix, it say's, "Phoenix is a tool used to install the Nutanix Controller VM and provision a hypervisor on a new or replacement node in the field. You can download a Phoenix ISO file from this page. Each Phoenix ISO file is for a specific hypervisor and Acropolis base software (NOS) release." But then when filtering, it shows Phoenix versions 2.1.1.1 to 3.0.4 are for Hypervisor "All". And then Phoenix version 2.0.4 has seperate downloads specificlly for KVM, HyperV, or ESXi, depending on which Hypervisor your are deploying. Which Phoenix download are you supposed to use if wanting to deploy an ESXi 5.x or 6.x Hypervisor on the nodes in the field?
We moved a NX3000 to a new environment but one of the nodes died. So we had to reimage that node. The other two where still up and running. But after a power-failure on the rack, the two nodes rebooted but won't come up anymore.

Hi, I apologize in advance for the long post !!!! From the information I've reviewed, the Xpress Models (I'm looking at Lenovo's offering) will support a maximum of 4 nodes. In addition there is no Protection Domain. Let's pretend that I'm a cloud provider for multiple customers, and I host their (Domain/File/Print/Email/Sql) servers in my 4 node domain. I want to use an (Acronis/Storagecraft) in VM backup software. These products store their backup images to a NAS/Share. If I setup a second 3 node Xpress Model that is storage "heavy" running Acropolis File Services, as a NAS/Share destination for my backup images, is there any restriction that you can think of that would prevent/limit me from doing this ? Right now we use StorageCraft and save to a Windows Storage NAS that has RAID 10 and I'm concerned that writing to will not be able to handle the I/O? I'm guessing that the 3 node Xpress AFS will easily handle intensive I/O writes. On weekends, the Full backup runs a

Need details how to store passwords as a secure string and use in a script for access to multiple Prism sites. I have a script to collect storage data from multiple Nutanix sites via Prism. Now I need to remove the plain text passwords. I have located references but only find "NOTE: for security reasons we should store our passwords as a secure string, by declaring these as variables before starting PowerShell." Can anyone provide the steps required to make this work?
Hi, I'm doing a PoC for a client, and I can't browse to Prism with 1 of the CVM IP address. The rest are OK. The cluster is up and running with no error. seems the httpd service unable to start. how do i fix this? below is the error snapshot.

Hi folks, Do you guys have ever think about the question. I read some guides and confused now. 1) node memory number: It seems every type of node has different supported memory number configuration: For NX-1064-G4, It shows only support 16x dimm ! What happens if I install any number， i.g 1, 2, 3,4,5,6 or any number [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1450i89B4BCCDB3F2197B.png[/img] 2) node memory installed slot location: It also says there`s an fixed slot order for different number dimm scenario. what happens if I install dimm not according to the guide ? [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1451iA5BA4F2ED2C9A97B.png[/img] 3) memory type: LR or R DIMM it also says there`s two type dimm, How to confirm which type is supported by specific type of node ? P.S my environment I have a node NX-1065-G4 with default 64g(4x16g installed in 1a,1b,1e,1f) and now I add two additional 16g dimm into slot 1g,1h. It work fine till now. but my me
Hi, Does anyone have a step-by-step guide on creating a Windows cluster on ESX on Nutanix? I've seen various examples online of using ISCI, SMB etc file shares but I'm not entirely sure on what to do. I've got the cluster as far as the file share witness working but how do I then configure the disks that make up the cluster resources? I will eventually be clustering SQL 2012 on this. Cheers, Steve
I was wondering is it possible for the next version of PRISM central to have the look and feel of 4.5.x but with the capacity monitoring features of PRISM Pro in 4.7.x? Personally I feel that it is a hassle to click "PRISM element" everytime in order to drill down into a particular cluster for 4.7 whereas in 4.5 I can just click the left sidebar and go into it from the main page.
