Find what are the options for a parameter in the API developer Guide

Hi, I have troubles to use Prism API v3 using the reference guide. For exemple I don't see the different possible options for an attribute. I explain myself with a quick example: If I want to create an alert with api using the reference guide below https://developer.nutanix.com/reference/prism_central/v3/api/alerts/postalertsnotify the attribute "notification_type" is required and must be a string. But what kind of value is expected here? I need to know what are the possible values, and what does mean each value. This is just an example, but it is the same for all other API end point. At this point API becomes a headache for me... Do I miss something here? Thank you for your help

Repost:Communication trouble of CVM when building CE on Nested ESXi

# On March 4, I posted the following but I have written the wrong answer myself, and the status of that bank has become "solved". # Actually it remains unresolved.

Containers

Would I be able to create storage containers in my cluster for the purpose of "pinning" VMs only to hosts that are assigned to the containers - restricting VMs to the hosts that belong to the container? The need is to control VM migration during Software Upgrades due to multicasting issues with the hosts.

controller vm's

I'm trying to get a better basic understanding with regards to controllers in a VM farm's data path. We are going to be in the process of migrating some of our farm resources to another data center which may include powering down controllers in a rolling fashion. What type of service interruptions would users expect to see?

Guidance on Sockets, Cores, Logical Processors

Hello again CE community! I'm running a Dell R730 with these specs: 2 Sockets 8 Cores Each Socket 256 GB RAM I'm running ESXi to run a 4-node cluster and want to parcel the CPU and Memory evenly among the 4 CVMs. Q1: Based on this, what should my CVM CPU/RAM settings be? Q2: When I allocate vCPU and RAM for VMs, how do I translate a bare-metal config spec e.g. 4x WS2016 8 CPU, 32 GB RAMto Nutanix VM specs, based on these constraints? I just need an example to shine light on how to break down the physical to esxi to nutanix CVM to VM specs. Thanks in advance, Brit

Layer2 Issue - AOS 5.5.8 - AHV

I have a problem with arp requests on the bridge for guest traffic In the drawing below the current architecture. If a request arrives from the outside, passing through the firewall, and the firewall is starting to communicate to a VM connected to a NIC to BR1-UP bond of BR1 bridge, the ARP request for the resolution of the VM address stops at the bridge BR1 and do not reach the VM, in this case the firewall and VM ARP tables remain unpopulated and the communications stop. On the other hand, if the communications depart from the VM to the Firewall (for example with a ping) the ARP request is processed by the firewall and the ARP tables of firewall and VM are correctly populated with the respective MAC ADDRs. Firewall IP and VM IP are in the same broadcast domain, no routing. I checked with Wireshark on the windows VM, with tcpdump and ovs-appctl fdb/show on the Nutanix host and when the communications start from the firewall the ARP request goes up to the physical card of the BR1

Nutanix Cluster API v2 reports normal status when a node is "down"

Yesterday our Nutanix CE cluster suffered a node loss (onboard NIC went offline somehow, investigating), HA failover performed correctly, but I had Zabbix monitoring cluster API 2.0 which did not state there is a problem. The only difference was that the host stopped being visible in the discovery by its proper name and remained only by IP, every other reading were "normal" and "not degraded" and even cluster state was reported "normal" during host effective downtime. WTF?! Also, WTF is with re-posting a question to another forums when asked to? Do you maybe have crosslinks allowed to ask the same question in a different subset of forums?

DR Scenario

Is it possible that we deploy a Nutanix AHV environment at the DR site and replicate from the existing ESXi environment at the Production site to the Nutanix DR site somehow? We are currently using Veeam backup and replication for VMware for backup. What is the possibility of such a requirement?

Now the hardware is same. 1x 240 GB SSD, 2x 500 GB HDD, 3x 1TB HDD. 128 GB RAM Boot from USB. 3x 1 TB drives are in Raid0 - Storage 2x 500 GB drives are in Raid0 - ISO's 1x 240 GB drive is in Raid0 - OS - (I tried this with Raid and with out raid.) this time when it is checking the disks it says "MinimumRequirementsError: A set of disks matching the minimum requirements was not found" is there any changes to the minimum hardware requirements with new version of CE? Please help me with this. Thank you, Krishna

Does Data Locality Really Matter?

GV Govindasamy (Nutanix Senior Solutions and Performance Engineer ) has written a series of three blog posts on data locality, I thought I would summarize and share them here. Be the first to reply with a question below. Does data locality really matter? Does data locality matter in HCI Architecture? Data locality is not just about storing new data in local node. It's also about keeping relevant useful data local when needed for low latency access. Read more. Can data locality help scale throughput? X-Ray's throughput-scalability-random-reads and throughput-scalability-sequential-reads tests help answer the following: Can IOPS or throughput rate sustain over time? As number of nodes grow in cluster, can throughput or IOPS scale with it? Read more. What if Data Locality was not a design choice in Nutanix AOS? What if data locality was not considered in Nutanix AOS architecture like a few other HCI architectures available in the market? Would AOS suffer the same as other ar
