Sovereign Open-Source Virtualization

The Full Proxmox HCI
Architecture Blueprint.

A production-grade, licence-free virtualization stack engineered by Tuah Packet: Proxmox VE compute, self-healing Ceph software-defined storage, Proxmox Backup Server immutability, and a 25G/100G zero-trust fabric - with a documented migration path off Broadcom VMware.

The Stack

Four Layers, One Resilient Platform

Every component is open, auditable, and independent - no per-core licensing, no vendor lock-in.

Layer 1 - Compute

Proxmox VE (KVM + LXC)

Enterprise hypervisor running full KVM virtual machines and lightweight LXC containers, with live migration, integrated HA manager, and the Corosync-based cluster quorum.

Layer 2 - Storage

Ceph SDS (Self-Healing)

Distributed, software-defined storage with 3× replication or erasure coding. The CRUSH map rebalances automatically when a node or OSD is lost - zero storage outage on failover.

Layer 3 - Data Protection

Proxmox Backup Server (PBS)

Deduplicated, client-side-encrypted, ransomware-immutable backups with instant restore and verification - the foundation of the DR architecture.

Layer 4 - Network

25G/100G Zero-Trust Fabric

Spine-leaf switching, RoCE/low-latency Ceph interconnect, segmented management/compute/storage VLANs, and micro-segmentation aligned to zero-trust principles.

Ceph Cluster State HEALTH_OK

Aggregate NVMe IOPS 340,000

Fabric Throughput 100 Gbps

SLA Response Speed < 15 mins

FIG. 01 - Alternative Reference: Proxmox + Ceph (5 Nodes)

Alternative reference design: five-node Proxmox VE + Ceph all-flash cluster on a dual 40GbE switch fabric - compute layer, distributed Ceph storage cluster, network design, per-node specification and capacity example. — Alternative reference build: five nodes, all-flash Ceph, dual 40GbE fabric and immutable backup in one view.

Stack Comparison

Proxmox HCI vs Broadcom VMware

What changes when you move off per-core subscription licensing.

Dimension	Broadcom VMware	Tuah Packet Proxmox HCI
Licensing model	Per-core subscription, mandatory bundles	Open-source, no per-core licence
Cost trajectory	Multiplied after Broadcom acquisition	Predictable - hardware + support only
Storage	vSAN (separate licence tier)	Ceph SDS built-in, self-healing
Backup	Third-party + separate licensing	PBS dedupe, immutable, encrypted
Vendor lock-in	High	Low - open, portable, auditable
Local support	Vendor / distributor chain	4-hour on-site SLA from Bangi, MY
