The Challenge

Broadcom Price Hikes & Nutanix Core Traps

Proprietary hypervisor renewals are crippling IT budgets with forced per-core bundles, mandatory 3-node HCI minimums, and unexpected surprise audits. Moving away is complex—unless you have the right migration partner.

The Proprietary Trap

VMware & Nutanix Lock-In

  • ✕ Punitive Core Billing: Costs scale aggressively whenever you upgrade to high-density CPU hardware.
  • ✕ Forced Architecture: Nutanix forces mandatory HCI and 3-node minimums, rendering your existing SAN/NAS investments useless.
  • ✕ Expensive Ecosystem Add-Ons: Mandatory 3rd-party backup licensing (Veeam/Commvault) and Kubernetes management (NKE) overhead.
  • ✕ Vendor Dependency: Sudden policy shifts, forced upgrades, and unannounced price hikes up to 5x–10x.

The Lexton-it Way

Open-Source & Sovereign

  • ✓ Predictable Flat Per-Socket Subscriptions: Costs stay fixed regardless of how many CPU cores or VMs you run per host.
  • ✓ Storage Freedom: Deploy native Ceph HCI or directly attach existing Fiber Channel, iSCSI, ZFS, or NFS arrays without extra fees.
  • ✓ Native Integrated Backup: Native Proxmox Backup Server (PBS) provides deduplication, client-side encryption, and immutability.
  • ✓ 100% AGPLv3 Core: Pure open-source software with no feature lockouts, CPU limits, or artificial paywalls.
Strategic Vector Matrix

Architectural Breakdown

Compare Proxmox VE backed by Lexton-it against traditional proprietary virtualization platforms.

Strategic Feature VMware vSphere Nutanix (AHV + AOS) Proxmox VE + Lexton-it
Licensing Model Multi-year per-core bundles Per-core subscription tiers Flat per-socket support / 100% Free AGPLv3 Core
Storage Architecture vSAN (Licensed per TiB) Proprietary AOS (Mandates HCI model) Flexible: Built-in Ceph (HCI) OR existing SAN/NAS (FC/iSCSI/ZFS/NFS)
Container Support Tanzu add-on fees Nutanix Kubernetes Engine (NKE) overhead Native LXC containers directly on hypervisor + SUSE Rancher K8s
Backup & Recovery Requires 3rd-party software Requires 3rd-party licensing Native Proxmox Backup Server (PBS) included (Deduplication + Immutability)
Hardware Lock-in Strict HCL restriction Strict Hardware Compatibility List Hardware Agnostic: Reuses existing server infrastructure easily
