Everything a serious private cloud needs
HA, hyper-converged storage, live migration, backups and SDN — engineered together, operated by our UK NOC.
True HA Clustering
Corosync-quorate Proxmox VE clusters with automatic VM failover — lose a node and your guests restart on a healthy host in seconds.
Hyper-Converged Ceph
Ceph RBD on the same nodes — replicated or erasure-coded pools, self-healing, no SAN to fail. Block, file and S3 from one fabric.
Live Migration
Move running VMs between nodes with zero downtime for maintenance, balancing or hardware refreshes — over a dedicated 25 / 100 GbE migration network.
VMs and LXC Containers
Run full KVM virtual machines and lightweight LXC containers side-by-side, managed from one Proxmox web UI and API.
Proxmox Backup Server
Integrated, deduplicated, incremental backups to a dedicated PBS appliance — instant file-level restore and verifiable backup chains.
SDN & VLAN Networking
Proxmox SDN with VLANs, VXLAN and EVPN. Per-tenant networks, private inter-VM fabrics and integration with our AS48825 edge.
600 Gbps DDoS Included
Always-on, in-line Corero SmartWall mitigation on every public IP. No add-on fees, no opt-in.
Managed by UK NOC
We run the cluster — Proxmox VE upgrades, Ceph health, PBS verification, kernel patching, capacity planning — handled 24/7 from Cambridge.
What's running on the cluster
A complete, integrated stack — installed, hardened and supported.
| Component | Role | Notes |
|---|---|---|
| Proxmox VE | Hypervisor & cluster manager | KVM + LXC, HA groups, replication, SDN, web UI & API |
| Ceph (RBD / CephFS / RGW) | Hyper-converged storage | Replicated or erasure-coded, self-healing, scales online |
| Proxmox Backup Server | Backup & restore | Incremental forever, dedup, encryption, verify jobs |
| Corosync / Pacemaker | Cluster quorum & HA | Sub-second failure detection, automatic VM restart |
| Proxmox SDN | Software-defined networking | VLAN, VXLAN, EVPN, per-tenant isolation |
| Cloud-init / Terraform | Provisioning & IaC | Templates, golden images, automated VM rollouts |
Who we run Proxmox clusters for
From private clouds to VMware migrations — same UK metal, same UK NOC.
Private clouds
Drop-in alternative to VMware vSphere — same HA, live migration and shared storage, without per-core licensing or hyperscaler bills.
Multi-tenant platforms
MSPs and agencies running isolated customer VMs with per-tenant networks, storage pools and quota — all behind one managed cluster.
Compliance & data sovereignty
UK-only Proxmox + Ceph clusters for finance, healthcare, legal and public-sector workloads — ISO-aligned operations, no overseas replicas.
VMware migration
Tired of Broadcom pricing? We migrate ESXi and vSphere estates to Proxmox + Ceph with planned, low-downtime cutovers and full rollback.
A proper reference architecture
Every cluster is engineered to your VM count, IOPS, durability and growth targets — not pulled off a template. Separate cluster, migration and storage networks; failure-domain-aware Ceph placement; verified PBS backups; tested failover from day one.
- Three networks, not one — public, Corosync cluster and Ceph/migration on separate 10/25/100 GbE pairs for predictable performance under load.
- CRUSH-aware Ceph — placement across hosts and racks so the cluster survives real-world failures, not just disk loss.
- Tested HA & restore — we pull a node and restore a VM from PBS before handover. You see it work before you sign off.
- Monitored 24/7 — cluster quorum, Ceph PG health, PBS verify status, version drift and capacity — handled by our NOC.

Operations : Fast2host UK NOC, 24/7Configurations are illustrative — every cluster is sized to your workload.
How to get started
01
Design the cluster
Tell us VM count, vCPU / RAM totals, storage capacity and durability goals. We size nodes, choose replica vs erasure coding, plan the SDN topology and the right migration network.
02
Build & bootstrap
We rack the nodes in Cambridge, cable separate cluster and migration networks, install Proxmox VE and Ceph, configure HA groups, PBS and SDN, then run failover and recovery tests before handover.
03
Operate & scale
We monitor cluster, Ceph, PBS and SDN 24/7 — handling upgrades, OSD replacement, capacity expansion and incident response. Add nodes online; the cluster rebalances itself.
Proxmox cluster questions
Nodes, Ceph, HA, backups and VMware migration — the questions our UK NOC answer most often about managed Proxmox VE clusters.
- Proxmox VE + hyper-converged Ceph on HPE ProLiant
- HA failover, live migration & Proxmox Backup Server
- Fully managed or root access — your choice
