What would you consider instead of VMware for a mostly VM environment?

Our VMware contract has ended, and we are weighing renewal against Nutanix and OpenShift Virtualization. We have 30 production hosts, three disaster recovery hosts, local storage and a SAN. We also use SRM for disaster recovery.

Our team has four administrators. One has cloud OpenShift experience, but not on-premises experience. Nutanix HCI was ruled out for our current servers, so a three-tier design is being discussed. OpenShift was quoted at roughly half the Nutanix price, which was roughly half the VMware quote. We also have security policies, audits and PCI DSS requirements. What would you look into before choosing?

OpenShift Virtualization is worth a pilot at that price, but don't treat it as a cheaper VMware with a different console. OpenShift is a Kubernetes platform, so your team would be taking on a different control plane and operating model just to run the VMs.

I'd test the on-premises install and upgrades in your restricted network first, then bring the other admins into the exercise. Check that your SAN has a supported CSI driver for the storage features you need, and test backup, restore, migration and disaster recovery rather than assuming the existing VMware workflows have equivalents.

The air-gapped work deserves its own estimate. A lower license quote won't help much if maintaining the environment falls on one person.

Nutanix is probably closer to the familiar VM administration model, but I'd want a detailed design for the proposed three-tier setup before comparing quotes. Confirm support for the exact servers, SAN and software versions, and ask how local storage for preproduction and cloning would work.

Also get the renewal terms and a multi-year cost comparison in writing. Nutanix pricing can vary a lot between customers, so neither a good initial quote nor a warning about renewals tells you what your own renewal will cost.

The three-tier design is the part we have the least information about, so a supported configuration and a demo would help.

Put disaster recovery near the top of the evaluation. SRM is part of your current setup, so ask each vendor to show how recovery plans, failover and failback would work with your three recovery hosts and storage. Test a restore too. A platform that runs the production VMs but leaves you rebuilding recovery procedures from scratch may not be the cheaper option.

Check the exact wording of the internal policy before ruling out open-source options. PCI DSS does not itself prohibit open-source software, and OpenShift also includes open-source components. Your organization may still require particular support or approval terms.

If those terms permit it, Hyper-V, Proxmox, XCP-ng or OpenNebula could be worth a look alongside the current shortlist. They still need the same hardware, storage, support and recovery checks.

Don't throw out the VMware renewal quote just yet. Even if it's more expensive, compare it with the migration effort and the cost of training and support for a new platform. Confirm the proposed license duration and what the next renewal would require, rather than assuming the current terms will continue.
