Nutanix CE installation fails

I am attempting to Install CE on a HPE Proliant DL380Gen10 server with 128GB RAM, two Xeon 4116 cpus, one 480 SSD, and four 600Gb HDD’s I created a USB install drive using Rufus and the newest version of CE. I get all of the way through setting up the drives and networking and the process appears to be going well until the part way through the ‘Hypervisor installation in progress’, then fails with Mount /dev/None does not exist message.

upgarde AOS only without upgrading the esxi

Hello Experts,It is possible to update the cluster to a version of AOS that supports ESXi 6.7 U3. However, we do not have a license for ESXi 7 or 8.We must upgrade and deploy the PC. The current version is 5.20.3.5. After reviewing the compatibility matrix on the Nutanix portal, I discovered that this version of AOS 6.5.3.7 is compatible with ESXI 6.7 U2 and U3. did any one tested that before ?and i would like to deploy PC,PS : this cluster has esxi 6.7 u3 as hypervisor

Which goes first Host or CVM?

Newbie trying to configure Nutanix.Setup:Dell server with iDRAC VLAN’s are setup on the switch Nutanix is installed. Both the Host and the CVM have an IP address in the same VLAN (100)Questions:Should I configure the VLAN on the CVM first or on the host? It seems if I configure the CVM first I can then configure the host. If I configure the host first I can’t get to the CVM. (expected) When I configure the CVM it never seems to return so I have to hard reset the host. Setting the CVM tag back to 0 it does come back.Commands:On the host: ovs-vsctl set port br0 tag=<vlan tag> On the CVM: change_cvm_vlan <vlan tag>

New install (bare metal r820) of CE (Phoenix 6.8.1) Can't select virtual disk for CVM

Hi all, new to Nutanix here likely for the same reason a million other folk are trying it out. I’ve managed to find the download (though not exactly straight forward) for Phoenix 6.8.1 CE and am attempting to first time install on an r820 with 5 enterprise ssd sas in front bay. I’ve split the first off into it’s own virtual drive at full capacity (300something gb) for H install. The second and third off into their own individual virtual drives for CVM1 and CVM2. Then the last two combined into one virtual drive for D.  I am able to select the virtual drives for H and D however the CVMS tell me it can’t be selected because the drives must be SSD which they are. Drives are fine and the virtual disks are recognized just not allowed to be selected. Any insight is greatly appreciated I’d love to test Nutanix out but documentation has been all over and even downloading (from a link in a seemingly random forum post) my confidence is a bit waned.

How does CVM handles data?

I have learned that Guest VMs transmit data to AHV and AHV reroute data to CVMs. Then, CVMs transmit data through PCIe passthrough (I haven’t got this point because CVMs still VM. so, it can’t bypass its hypervisor) to HBA hardware. After that, HBA transmits data to disks. But I want detailed data flow that explain hardware and software (like Curator, Medusa… etc) data flow from guest VM to the disks because it will be useful for troubleshooting and confidants while working with Nutanix Solution. Could anyone help me?

How does RDMA work without needs CPU?

I'm surprised how RDMA connect different memories through NIC without needing CPU. Memory is volatile storage and NIC is network I/O. they can't perform anything and can't understand application needs!
