1. Dedicated EPYC 9645 & DDR5 ECC
G12.5 Root Servers position compute on AMD EPYC™ 9645 ("Turin" Zen 5) cores paired with error-correcting DDR5 memory, eliminating noisy-neighbor CPU steal time for databases and low-latency workloads.
2. Server Control Panel (SCP) & Firewall
Manage power states, hypervisor-level stateful firewall rules, NIC throttling, and rescue boots via the SCP dashboard or automated REST/Webservice API.
3. Cloud-Init API & Custom ISO Images
Deploy official Linux cloud images with automated Cloud-Init YAML user-data, or mount custom ISO files (Debian, FreeBSD, Proxmox VE, Windows Server) via virtual DVD drive.
4. Out-of-Band HTML5 VNC & Rescue
Access your server’s video output and keyboard directly in the browser via HTML5 VNC even if SSH or guest networking is broken, or boot into the live Debian Rescue System.
5. Copy-on-Write Snapshots & Export
Create instant Copy-on-Write (CoW) disk snapshots before kernel or database upgrades, roll back in minutes, or export offline snapshots over HTTPS to local storage.
6. 2.5 Gbps Network, IPv4/IPv6 & PTR
Every Root Server includes an unmetered 2.5 Gbit/s network interface (temporarily shaped to 300 Mbit/s only if rolling 24-hour traffic exceeds 3 TB), 1 static IPv4 (/32), 1 static IPv6 (/64) subnet, and full self-service Reverse DNS (PTR) configuration.
Netcup Root Server Frequently Asked Questions
What makes a Netcup Root Server different from a regular VPS?
While both use KVM virtualization, Netcup Root Servers allocate guaranteed, dedicated AMD EPYC processor cores (AMD EPYC 9645 "Turin" Zen 5 on G12/G12.5) and dedicated DDR5 ECC RAM, plus faster 2.5 Gbit/s network ports and NVMe storage.
Do all Netcup Root Server generations (G11, G12, G12.5) have identical specifications?
No. Generation 11 used AMD EPYC 9634 (Zen 4) CPUs with larger base NVMe disks (e.g., 256 GB on RS 1000). Generation 12 upgraded to AMD EPYC 9645 (Zen 5). Generation 12.5 kept the Zen 5 CPU and DDR5 ECC RAM for new orders while halving base NVMe capacities (e.g., 128 GB on RS 1000) and adjusting monthly rates on RS 2000–8000.
Can I mount custom ISO images and use VNC on a Netcup Root Server?
Yes. Through the Server Control Panel (SCP), you can attach custom ISO images (such as Proxmox VE, FreeBSD, Alpine, or Windows Server) via a virtual DVD drive and perform full out-of-band installations over the HTML5 VNC console.
Which Netcup Root Server coupon offers the biggest discount?
