1 gig ports

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?

Compression and vDisk

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.

IPMItool Full Duplex Command

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

Shellshock Bash Vulnerability

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?

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...

Upgrade Software to 4.0.1

Has anyone toyed around with the Upgrade software module in the 4.0 GUI? I'm looking to upgrade to 4.0.1 using the GUI. The two query boxes need both the NOS Metadata File and the NOS Binaries. I was able to download the 4.0.1 .tar file from the support portal but I can't seem to find the Metadata File associated with it.

Adding fifth disk to 1050 Nodes

I added a 1TB disk to each of my 1050 nodes. I followed the guide and added them correctly. Just noticing that in hyper-v though it still shows the 6th disk as completely free.

Hi, In the Nutanix Bible : http://stevenpoitras.com/the-nutanix-bible/#disk_balancing Steven explains the feature "disk balancing", and wrote : [spoiler]"Disk balancing leverages the NDFS Curator framework and is run as a scheduled process as well as when a threshold has been breached (eg. local node capacity utilization > n %)"[/spoiler] what's the percentage of this parameter ? And can i check and/or change this number ? Thks ! Sig'

Is there a metric to track compression ratio over time?

I just turned on compression on a couple clusters. I'm wondering if there is a metric somewhere that tracks compression ratio over time? Trying to identify any trends on how much I can expect the data to compress.

Errormessage about disabled VM autostartup & vSphere HA cluster

Hey guys, We are busy building a Nutanix 3.5.3.1 infrastructure with vSphere 5.5. We have six nodes in two blocks, and the design consists of 2 Nutanix clusters with each its own vSphere cluster. HA is enabled on each cluster. We are getting an error on both Nutanix clusters in PRISM UI: [i]Virtual Machine auto start is disabled on the hypervisor of Controller VM [/i] Nutanix best practices recommend to enable "Start and Stop Virtual Machines with the system" on each host, and move the Nutanix CVM startup to Automatic startup. But, according to This VMware KB the automatic startup feature is disabled when moving an ESXi host in an HA enabled cluster. Just like the error message says. Is this expected behavior? Can this error message be disabled because it is just not valid in combination with VMware HA enabled clusters? Or is this still a configuration error?

vSphere 5.5U1 and NFS disconnects

Hello, It's made the news yesterday, but in case you missed it, there seems to be a bug within vSphere 5.5U1 that affects all NFS users. NetApp & VMware (at least, maybe Nutanix too?) are working on the subject. See the post below for more information: http://datacenterdude.com/vmware/nfs-disconnects-vmware-vsphere/ That may also explain the delay from Nutanix in the support of the 5.5U1? Did you guys catch this while working no the 5.5U1 support? Sylvain.

Storage access for specific VM on a Nutanix VMware edition

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.
