Hi, I am currently trying to expand our existing Nutanix cluster but need to downgrade the version of ESXi as the one installed from factory (Dell) is too new. Unfortunately I'm unable to use the latest Dell customized ISO (5.5 U3) because it's not in the Nutanix iso whitelist. Following documentation I'm supposed to download the latest version of the file from the Nutanix portal but I'm unable to find it. It would be nice if someone of you would be able to assist me with this. Thanks, Dieter
Good morning. We are trying to size a new Cluster of Nutanix, we don't have a lot of money. We have 2 datacenters connected through 1 GB ethernet. We will have 25 virtual servers on the system. How manu Nutanix servers we need to buy to get HA and Disaster Recovery in the other Datacenter? It's possible to have 2 nodes in Datacenter A & 2 nodes in Datacenter B? Thanks a lot for your help
The customer I'm supporting has an internal Information Security/Information Assurance requirement that whereever possible, centralized authentication for privileged use/access should be deployed. For our Prism and Hypervisor environments, this is accomplished with Active Directory/LDAPS integration with the Enterprise Microsoft domain. However, with not being as versed with the Nutanix CVMs and not wanting to 'break something' trying to incorporate them, we have elected for individual local user accounts on each CVM. In our environment today, that's not a huge undertaking, but it's certainly not convenient, and it's definitely not in-line with the customer's requirement for a single centralized privileged user administration. I've scanned the Nutanix Bible and the Nutanix Support documentation, but nothing has jumped out at me yet. Is anyone else aware of a documented (and supported) method in order to integrate the CVMs with Microsoft Active Directory?
Hi, The Additional Stats introduced in 4.5 for the Virtual Disks, such as Working Set, Random IO and the like, are they available for Hyper-V? I've seen three of our clusters, all running 4.6.1 where we have 0 Additional Stats which makes me wonder if they are actually working. Any input on this? Kind Regards
Hi, My SCVMM server and my Nutanix CVMs/VIP are in differents VLANs separated by a firewall. I need to know the ports required between SCVMM and CVMs/VIP (like the TCP5989 for CIM-XML) and in the other way from CVM to SCVMM for the setup_hyperv.py setup_scvmm to run correctly. I can't find it in the documentation. Regards, Alex
Hi, We are planning a new install where: [list] [*]we only have 1G BaseT (RJ45) ports on switches for now [*]we are arranging 10G fiber ports which may take some time [*]we want no changes later on in terms of configuration as we see no downtime [*]I understand we can add 2 x 10G and 2 x 1G ports in single Team (link speed will be 1G) [*]So once we have 10G fiber ports available we will simply disconnect 1G ports[/list]Please advise if above workable solution without any downtime or re-configuration requirement? Thanks, Noman
Hi Guys, I have running foundation to image my Nutanix Box, but one node stuck at 94% the last entry i get from the log looks like the following: 20160413 152058: INFO: Success running ls /tmp/svm_boot_succeeded 20160413 152058: Hyper-V first boot successful. 20160413 152058:INFO: Restarting host... The node is about 2 hours in this state - nothing changed till now. The other two nodes are imaged well without any problems. What are my possibilities? Reimage the whole cluster? Regards, Freddie
Hi Team, I would like to know if i turn off the HA on my SCVMM Virtual Machines and when the host down , will all the virtual machines in the host HA to the next available host? NDFS : 4 node cluster. NOS : 4.5 Hypervisor : Hyper-v The question arise because i am unable to turn on HA on the microsoft level in SCVMM due to host need to be patch to latest update. I am enquiries here that does Nutanix cluster itself provide HA to hyper-v ndfs cluster?

We are getting ready to deploy our first set of clusters and in the preinstall brief we hit a little snag regarding power. The specs state that with dual power supplies you need 208 volts per power supply. I have read in other post that the 3000 series should be OK with 120V if you only have 3 nodes. Can anyone confirm this? My goal is to have redundance if power was lost to a single power supply. If we get the 4th node we will go with 208V, but currently I just don't have that kind of power or mainly a 208/240 UPS.

Customer has two small VMware environments, each with only 2 Dell servers. First environment is running roughly 15-17 VMs for things like Active Directly, SQL Server and apps under VMware Essentials License which provides upto 3x dual socket servers. Second environment is running virtual approximately 30 virtual desktops under VMware View licenses for 30 seats. This license doesn't restrict how many sockets, just 30 active desktops. Since this is such a small environment, even with a conservative sizing, it can easily fit on a single cluster. The main issue is licensing. Now for the question - Is it possible to mix licenses on a Nutanix cluster with some nodes licensed VMware Essentials and some nodes licensed under VMware View?
I do not see an explaination as to why a single container is the best practice. Does having multiple containers cause more overhead(other than the memory use)? It seems like an obvious choice would be to put your OS VM's that are virtually identical in a deduped container to maximize space savings. Then put any user data vDisks in a compressed container. Just looking for some input on why this is not a good idea.
Hi folks ! My client asked me a quite though question today : since we are bounded to CISCO Nexus for physical switches, we digged on a low latency nexus with SFP+ connection. It seems that 3064-X is a good choice but as far as I know, Cisco SFP+ compatibility with 3rd party is azardeous. 2 questions : Are there some kind of hardware restriction w/ Nutanix Supermicro stuff appart from SFP+ cable (MOLEX 074752 series as far as I know) ? Is there a compatibility matrix of this granularity level somewhere ? best regards,
What is the recommended CPU performance setting for AHV? Im curious if AHV has the ability to interract with the Intel throttling or if it's better to just have it run full speed all the time. The CPU power options are: Performance Per Watt DAPC Performance Per Watt OS Performance Acropolis Hypervisor 201602173 Dell xc730xd nodes with 2 X Xeon E5-2630 v3 @ 2.40GHz The Dell Active Power Control (DAPC) mode allows the BIOS to manage the processor power states in order to achieve Performance/Watt maximized at all utilization levels and workload types while still meeting performance requirements. In the OS (Demand Based Power Management (DBPM) mode, the operating system (OS) controls the processor’s power management. In the Maximum Performance mode, the processor runs at the highest frequency all the time. [list] [*]Performance Per Watt Optimized (DAPC) This mode allows the BIOS to manage the processor power states in order to achieve Performance/Watt maximized at all utiliz
Hi , has anyone encounter any issue regarding firefox running on foundation 3.1 or 220.127.116.11 ? I've tried deployed or even upgrade my foundation from the older version to 3.1 and it seems that the same issue still happen on firefox.
