How do I set up a Proxmox cluster?

A Proxmox cluster requires a minimum of 3 nodes for proper quorum. Nodes communicate over a dedicated Corosync network and share configuration automatically. NodeSpace engineers handle the full cluster setup including networking, Corosync, fencing, HA groups, and Ceph storage.

Proxmox Solutions We Offer

From virtualization to email security to backup — we support the full Proxmox ecosystem.

Proxmox VE

An open-source virtualization platform for KVM virtual machines, LXC containers, high-availability clusters, ZFS, Ceph, and more.

Native ZFS & Ceph Support
Secure Web UI & API Access
Clustered or Standalone
No per-core licensing

Proxmox Mail Gateway

Protect your business with a robust anti-spam and anti-virus gateway, deployed on your own server or as a VM.

Spam & Malware Filtering
Detailed Reporting & Quarantine
LDAP/Active Directory Integration
SMTP and Gateway Modes

Proxmox Backup Server

Enterprise-class backup, restore, and deduplication for your virtual machines and containers.

Incremental, Encrypted Backups
Fast Restore & Deduplication
ZFS, XFS, BTRFS Support
Perfect with Proxmox VE

Proxmox VE on Bare Metal vs. Public Cloud

Run Proxmox directly on dedicated hardware without adding another virtualization layer underneath it.

Bare-metal deployment gives Proxmox direct access to the server's CPU, storage, and supported hardware features. That can be useful when you need predictable resources, ZFS, IPMI access, or PCIe passthrough.

Native KVM acceleration — no nested virtualization overhead
Direct NVMe and ZFS access for maximum I/O performance
Full IPMI/KVM for out-of-band management
PCIe passthrough for GPU and specialized hardware

High Availability (HA) & Ceph Storage Solutions

Eliminate single points of failure with multi-node Proxmox clusters and distributed storage.

Multi-Node HA Clusters

We build 3+ node clusters with redundant networking, ensuring your VMs automatically migrate if a node goes down. Corosync-based fencing and quorum keep your cluster consistent.

Ceph Distributed Storage

Replicate data across multiple nodes with Ceph. No single disk or server is a point of failure. Scale storage independently of compute with commodity hardware.

Live Migration

Move running VMs between nodes for maintenance, upgrades, or load balancing when the guest, storage, and cluster configuration support live migration.

Managed Proxmox Backup Server (PBS)

Enterprise-class backup infrastructure for your Proxmox VE environment, fully managed by our team.

Proxmox Backup Server provides incremental, deduplicated, and encrypted backups for your VMs and containers. We deploy and manage PBS on dedicated hardware, ensuring your backups are always running, verified, and ready for fast restores.

Incremental backups with client-side deduplication
AES-256 encryption at rest and in transit
Automated verification and integrity checks
Seamless integration with Proxmox VE clusters

Backup. Deduplicate. Encrypt. Restore.

Deployed on dedicated NVMe hardware with off-site replication options.

Broadcom/VMware vs. NodeSpace Proxmox

Organizations evaluating alternatives to VMware often consider Proxmox VE because its architecture and subscription model are different. Here are the practical differences to consider.

Feature	NodeSpace Proxmox	VMware/Broadcom
Licensing Model	Open source — no per-core fees	Per-core subscription bundles
Annual Cost (16-core server)	$0 license + hosting	$4,000 – $8,000+ in licensing alone
Hypervisor	KVM (Linux kernel)	ESXi (proprietary)
Distributed Storage	Ceph (integrated)	vSAN (additional license)
Backup Solution	PBS (free, integrated)	Requires Veeam or third-party
Container Support	Native LXC containers	Requires Tanzu (enterprise tier)
Web UI	Included — full-featured	vCenter (additional license)
Infrastructure	We own our hardware	You provide or rent separately
Migration Assistance	Included

Scale your infrastructure based on your hardware, not your license budget.

Planning a VMware or Proxmox Migration?

Migration work depends on the source platform, guest operating systems, storage layout, network design, and acceptable maintenance window. We can help plan the target infrastructure and migration approach before anything is moved.

For larger environments, contact us with the approximate VM count, storage footprint, network requirements, and availability goals so we can scope the project correctly.

Frequently Asked Questions

Proxmox VE benefits from ECC memory, fast storage, and enough CPU capacity for the planned guests. Cluster and Ceph designs may also require dedicated high-speed networking. NodeSpace can recommend a dedicated server or custom configuration based on the environment you plan to run.

A Proxmox cluster requires a minimum of 3 nodes for proper quorum. Nodes communicate over a dedicated Corosync network and share configuration automatically. Our engineers handle the full cluster setup — networking, Corosync, fencing, HA groups, and Ceph storage if needed. Check out our Proxmox installation guide for more details.

Yes. We specialize in VMware to Proxmox migrations. Our engineers convert VMDK disks to QCOW2 or raw format, reconfigure networking, and validate performance on the new platform. We've migrated hundreds of VMs for organizations looking to escape Broadcom's per-core licensing model.

Proxmox VE is a mature virtualization platform with KVM virtual machines, LXC containers, Ceph storage, HA clustering, and a web interface. Its subscription model differs from per-core licensing models, but whether it is the right replacement for VMware depends on your workloads, operational requirements, and migration plan.

Yes. All NodeSpace Proxmox deployments include 24/7 access to engineers who understand clustering, storage, and networking best practices. We offer initial setup, ongoing monitoring, security updates, and troubleshooting. For enterprise needs, we also provide custom consulting engagements.
