can I Separate cvm mgmt and esxi mgmt

Hello Folks, NX-1065 has only two 10G port, and two 1G port. and I have only one pair of 10G switch, and one pair of 1G switch. In my opinion, I`d like to make ESXI port(mgmt, vmotion,nfs vmkernel), and CVM port(prism mgmt, cluster mirror ) run on 10G switch, and configure 10g switch uplink to other network which I can connect to ESXI MGMT and prism. make vm data port connect to separate 1g vswitch. but network guy told me the 10g switch can`t uplink to externel network, so I`d like to know Can I move the ESXI port (mgmt) and CVM mgmt(VIP) to 1G vswtich， and create addtional vmotion,nfs kernel port connected to 10G vswtich, also leave CVM cluster mirror interface connected to 10G vswtich. networking design is the key things.

Migration from "Legacy" ESX to Nutanix ESX

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.

Strange CVM / Hypervisor interaction

We are spinning up some new ESXi 6 clusters and have encountered some strange behavior on 1 of these clusters. The CVMs periodically contact the host machines to gather various stats. All logging seems to indicate this process is working properly, but every few hours to few days we will have a host lose connection to vCenter, and stop responding to all remote management requests (SSH, etc.) It appears that the VMware hostd service simply runs out of resources and stops responding. The only way to remedy that we have found so far is restarting the host completely. In some instances the host console was still responsive, but attempting to restart the management services was unsuccessful. We have ensured all passwords are congruent and have regenerated the certificates used to secure hypervisor to CVM communication. Has anyone seen anything similar?

512n or 512e Disk

Hi Guys, Is there a difference between 512n or 512e with Nutanix? Vmware doesn't support 512e but vendors are quoting 512e with their config. Any difference in performance? Is one better than the other?

changing cluster RF from RF2 to RF3

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

container_mount_check fail

Hello Guys, I need your help because I run into a strange issue with my Nutanix cluster (NOS 4.6). Nutanix generates a warning as below: "Data Protection > Protection Domain > Container Mount > Containers are not mounted on all nodes".

Windows 2012R2 Cluster

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

Automatically Email NCC Results

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?

Moving From vCenter Server to vCenter Appliance

I have a 3-node cluster for VDI running ESXi on all three nodes. At the moment vCenter (v6.0) is running on a single virtual machine (this virtual server is on a physically separate cluster from the VDI/Nutanix one). I'm starting to look into how to go about moving from that vCenter server to the VMware vCenter appliance. What considerations would need to be made to get the 3-node Nutanix cluster to move from a Windows-based vCenter server to the vCenter appliance? Would there be downtime involved?

Xpress Configuration Scenario

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

New Deployment - Recommended version of Acropolis + vSphere

Hello, We have just recently stood up a brand new cluster and our prepping it for production use. Currnetly we are using acrpololis verion 4.5.2.3 + vsphere version 6.0. Curious to hear if anyone has any feedback in regards to any upgrades that we should consider prior to putting this into production. I know there are some CBT bugs w/ vsphere 6.0 and have also heard that there are some issues with certain combinations of acropolis + vsphere. If you've had stability with a particualr combination it'd be great to hear your feedback. Thanks in advance.
