Frequently asked questions
Which hypervisors do you pre-install?
Proxmox VE, VMware ESXi, XCP-ng, Hyper-V and Nutanix AHV. Nodes can be handed over pre-imaged with access details.
How many nodes do I need for high availability?
Three is the usual minimum for a quorum-based HA cluster. A single node suits a branch, a lab or a first workload, and can be added to later.
Do I need shared storage?
For live migration and HA in the traditional sense, yes. Hyper-converged designs distribute storage across the nodes instead — we size both and recommend on your availability target.
Can I start with one node and grow?
Yes, provided the first node is specified for the cluster it will join. That is the main reason to size the whole design before buying the first machine.
What testing happens before delivery?
24 to 72 hours of burn-in with CPU, RAM and storage stress, thermal checks and SMART review, then rack-ready delivery with the firmware baseline recorded.
