Great news for those using ACI in their environments, who might be used to ACI having visibility into their virtualized VMWare environments -- this functionality is coming to Nutanix!
From Cisco's release notes: "You can now integrate the Nutanix Acropolis Hypervisor (AHV) with Cisco Application Centric Infrastructure (ACI). The Cisco APIC integrates with Nutanix AHV and enhances the network management capabilities. The integration provides virtual and physical network automation and
VM endpoints visibility in Cisco ACI." https://www.cisco.com/c/en/us/td/docs/dcn/aci/apic/kb/cisco-aci-nutanix-integration.pdf
You need to be running:
Cisco APIC 6.0(3) -- (released August 2023) or newer
Nutanix: To use current vSwitches without creating a NEW vSwitch (no vSwitch creation):
Benefits of the integration are:
The image above shows a sample topology. The Cisco APIC manages the ACI fabric and policies. The VMs connected to the virtual switch are managed by the Nutanix Prism. ACI fabric provides network connectivity for VMs in AHV Hosts with the uplinks (Uplink1 and 2).
How it works:
Cisco ACI uses EPGs, or end-point groups, to deliver policy to sets of defined endpoints (i.e. VMs) within
ACI to NCP AHV with Flow Network Security as a VMM solution.

In no particular order:
1. Nutanix Central: A SaaS based cloud-delivered solution that will provide a single interface for managing ALL of your Prism Central deployments, whether on-prem, cloud or MSP. In early-access now(ish) with features set to roll out going forward.
2. Multicloud Snapshot Technology (MST) - This allows snapshots directly to cloud-native datastores in S3.
3. Project Beacon - This initiative takes aim to provide a portfolio of data-centric PaaS services available natively in the cloud. It's intent is to decouple applications and their data from the underlying infrastructure, giving developers greater flexibility to build applications once and run them across various environments natively on Nutanix or in the public cloud.
4. Nutanix Data Services for Kubernetes (NDK) - in early access. NDK is designed to deliver enterprise-class storage, snapshots and DR capability to Kubernetes.
5. NCP enahancements which include the ability to dynamically apply security policies across multiclouds enabling secure, seamless virtual networks using Flow Virtual Networking. Available now in NC2/Azure, and in development for AWS.
It was also a chance to meet up with old friends and make some new ones. NUG Chapter Champions in attendance met in the Solutions Expo for some hangout time and a group photo:
Shout out to all the Nutanix Technology Champions in the Day 2 General Session:
Great conference, nice venue. It was nice having the conference so close to home base. Hope to see everybody in 2024!
We had been running Nutanix successfully for years on the ESXi platform. We initially landed on ESXi because that's what we were using when we decided to move to HCI-first. In an effort to streamline operations, lifecycle management, we took a serious look at AHV as an option -- after all, it was included with the Nutanix licenses we were already paying for. We added an AHV cluster to our test lab and put it through the paces for a few months and then we decided it was ready for primetime, so we kicked off this project.
Challenges to overcome:
Phase: Execution & Migration
Here are the steps to move virtual machines from ESXi to Nutanix AHV using Nutanix Move:
With openDCIM, you can manage and track a variety of physical assets in your data center, including servers, switches, power distribution units (PDUs), and more. The software provides a web-based user interface for managing your data center infrastructure and includes features such as:
openDCIM is highly customizable, allowing you to customize it to meet your specific data center needs. A few customizable options:
The goal: move an entire production Citrix & VDI platform from ESXi to AHV. Below is our before (left) and after (right)
What is delivered:
•EMR sessions daily: 10000+
•VDI sessions daily: 4800+
•delivers 900+ general apps
•13000+ Citrix users
What makes it up:
•Published Apps (1155 servers)
•Infrastructure (69 Server)
•primary data center hosts- 110
•secondary data center hosts- 72
Workload & support challenges
The Citrix migration
The VDI migration
The migration was fairly painless and we actually saw improved density on the clusters running AHV instead of ESXi on top of AOS -- about a 10% improvement. The transition for our Citrix support staff was seamless.
The success of this project paved the way for our next project; converting our general production workloads from ESXi to AHV.
"Entering emergency mode. Exit the shell to continue."
There's already a VMWare KB article about this: "Failed to start file system check on /dev/disk..." error on Photon OS based virtual appliances (2149838) but in our case this did not resolve the issue.
What we did to fix the issue:
Restarted vCenter appliance and entered GRUB menu.
Added "fsck.repair=yes" after "consoleblank=0" and booted.
All vCenter services started and were working as expected.
