Get a glimpse of our technology behind Prepaid-Host.

Hardware

Our server cluster

We exclusively run current enterprise hardware from established vendors. The cluster is built around the AMD Milan generation: AMD EPYC 7443 with up to 24 cores per socket, ECC-Registered Samsung memory at 3200 MHz and Datacenter NVMe SSDs for minimal latencies. Every host is connected redundantly to our network, monitored continuously and protected at every layer. The result: consistent performance, even under load.

CPU: AMD EPYC 7443
RAM: Samsung DDR4 ECC · 3200 MHz
Storage: Samsung Datacenter NVMe
Network: 2 × 25 Gbit/s

Ceph — 3-way replication

Distributed storage, no single point of failure

Software-defined Storage

CEPH Distributed Storage

Storage does not live on a single machine. It is spread across our entire cluster. Ceph replicates every block of data three times across separate hosts (3-way replication). If a storage node fails, another one takes over automatically, without downtime and without data loss. Horizontal scalability lets us grow capacity without standstill; new hardware is integrated during operation.

More about Ceph

Network

Redundant 25 Gbit/s Infrastructure

Every host has two physical uplinks. If one port fails, the second takes over seamlessly.

Host uplink: 2 × 25 Gbit/s
Switch vendor: Arista Networks
DDoS protection: Arbor Networks — always active
Network transit: DE-CIX Frankfurt

FAQ

Infrastructure Questions

What is the difference between a vServer and a root server?

There is none. Every vServer is a fully KVM-virtualised root server with its own kernel and root access — no container, no shared resources.

Why Ceph instead of local storage?

Local storage means: if one disk fails, the data is gone. Ceph replicates every block three times across separate hosts. Even a complete node failure keeps all VMs running.

What does KVM virtualisation mean technically?

KVM (Kernel-based Virtual Machine) is hardware virtualisation built into the Linux kernel. Your VM gets its own kernel, dedicated CPU access and isolated RAM — no OS-level overselling.

How are the hosts connected to the network?

Every host has two physical 25 Gbit/s uplinks to our Arista switches. Both links are actively bonded — if one fails, the second takes over without interruption.

Where are your servers physically located?

In Maincubes FRA01 and NTT FRA2, both in Frankfurt am Main — a few kilometres from DE-CIX, one of the world's largest internet exchanges.
