I was looking for confirmation about a statement that I recently heard that the best practice for the power supply voltage for a block was 220 volts. And that if 110 volts was used, it was less likely that one power supply could handle the load if one power supply failed. Thank you.

True or False: The SSD boot drive on an NX-3450 also contains the cassandra metadata.?

Good afternoon, Can someone please sanity check something for me, one of the BEarena team is running a diagnostics test which is taking 7-8 minutes to deploy each diagnostics VM. What is considered to be a normal amount of time? At this rate the 8 node cluster will take over 1 hour to run diagnostics. Thanks Darryl

Does anyone know how to enable deduplication?I don't see my option in container update in my NX-1420

Dear All , For importing Vm's from the existing vmware envirronment to Nutanix cluster I extracted the below note from Nutanix admin doc. [i]Note: Due to a limitation with VMware vSphere, a temporary name and ip address of a controller VM must be used to mount the Target NFS datastore on both the source host and the target host for this procedure.[/i] 1.Could you please help in this what this temporary name and ip mean? the CVM ip addrress of the nutanix host is already configured ,shall i need to modify it ? or keep it as it is? 2. For target host (Nutanix Host) it is clear that it contains CVM but for the current (Not Nutanix Host) there are no CVM. 3.This should be done through adding storage on both hosts .Right? Mount the target NFS datastore on the source host and on the target host (you can mount NFS datastores in vSphere client by clicking Add Storage on the Configuration>Storage screen for a host) [b]so instead of using the CVM ip of the target host (Nutanix Host) in Se

Hello folks, What are the advantages and disadvantages for use of LACP to improve east/west traffic and prevent unnecessary north/south traffic? Are there any documents on it's use for a Nutanix installation? Is the use of LACP very common for Nutanix installations? Are there folks kicking themselves for not implementing LACP. Thank you for your opinions.

We are in the process of identifyng datacenter requirements for our Nutanix installation. One statement I recently heard was that the 1 gig ports for the nodes were primarily to address security concerns and that the 10 gig ports would satisfy most customers. Is this true? Are there any other downside issues to not using the 1 gig ports?

Hello, is there a NOS Hardening Guide available? two specific questions: is there a Firewall running on the CVM? can I install my own ssl certificate? thx and best regards Manfred

Hello - I am going through the NPP 4.x tutorial and I was wondering if someone can explain to me vDisks in the context below. I guess I don't fully understand what vDisks are. [i](Copied from the tutorial):[/i] [i]"If user data for VDI is kept on a vDisk that is attached to the end-user VM, you can store the user data vDisks on a compressed container and the VM vDisks on an uncompressed container."[/i] Thanks in advance.

Hello - Does anyone know if there is an IPMItool command to set the interface to 100MB full duplex? Is this option to change it even available? We are having some IPMI issue where connectivity drops every so often. We are working with networking to check their side, and we've done various things to test/isolate the issue. On the network switch side, the ports have been configured to 100MB from 1GgE. One suggestion that came up from networking is to set the IPMI interface to 100MB full duplex. Thank you. RV

Hello - I am studying for the NPP exam and the online guide talks about Foundation and Phoenix. Does anyone know if these utilities are available for download to customers? Thanks! RV

It looks like my CVM's running 4.0.1.1 are vulnerable to the now hyped-up CVE-2014-6271. What is the official Nutanix stance on remediating the vulnerability - should I wait for an NOS hotfix or can I pull down the relevant CentOS patch?

I am trying to create a Protection Domain, but can't figure out how to supply the name of the Protection Domain. I have to use a string and a JSON object as body parameter, but it keeps throwing errors.

Hello All, One of our customers decided to have Vmotion and ESXi MGMT on different VLANS and they will split the 10G connections. So for this kind of setup, which VLAN should CVM be in? Do you have any recommendations? Thank you so much...

We have a shiny new VMware NTNX environment, yeeh! Question: I'd like to be able to measure the virtual disk metrics for a specific workload (backup). Preferably without any layer in between so I can really see what the workload does. Idea is to use a virtual machine on NTNX as a backup server and see what kind of parameters I use for the backup storage. Is it possible to present a container on the CVM as an SMB share and write my backup on it? Or would it be best to use the Windows NFS client to access an export on the CVM? Background: I'd like to purchase a separate storage platform for the backups. But since I'm not really sure what kind of IO patern and throughput I need to sustain, I'd like to test and measure before we buy.

Hi , I have run below command to show my hypervisor password from one of the CVM , but the password doesn't come out , anyone can help ? Command : zeus_config_printer 2> /dev/null | grep "hypervisor {" -A 3 Result: nutanix@NTNX-14SM36060045-A-CVM:192.168.1.208:~$ zeus_config_printer 2> /dev/null | grep "hypervisor {" -A 3 hypervisor { address_list: "192.168.1.204" username: "root" }-- hypervisor { address_list: "192.168.1.206" username: "root" }-- hypervisor { address_list: "192.168.1.207" username: "root" } Apart of it , can anyone share where is the password configuration Hypervisor and CVM store in nutanix system? (from book it said store in ZEUS , but i don't know exactly the path location ) Thank. ;) Regards, Zack

We would really like to use the distributed switch in VMware cluster. There seems to be a lack of documentation on how to properly implement it with Nutanix. For example I seem to remember that the Nutanix controller VM’s should not be moved from their installed switch and they have to be able to talk to vSphere and or the ESXi hosts. But if I want to put vSphere and the ESXi hosts into the dvSwitch and how do I do this? I might not be wording this question correctly, but one of the goals would be to have traffic separated by VLAN and protected by QOS where necessary. Is there documentation on how to do this correctly in a Nutanix environment? Has anyone tried to do this?
